Superheat and Subcooling: How to Measure Them

February 7, 2018 by Sindy Aubrey

This brief guide explains how to measure superheat and subcooling. As a review, superheat is heat added to the refrigerant above its boiling point/saturation. Subcooling is removing heat from refrigerant below saturation. Measuring the superheating and subcooling of the refrigerant tells you if it is under the proper amount of pressure and can lead to a diagnosis of the refrigerant level and mechanical issues.

Step-by-step instructions on how to calculate superheating and subcooling values plus possible diagnosis using the measurements are included. Furthermore, the tools, tips, and techniques below assist you in streamlining the process for faster maintenance and diagnosis of the problem.

Why You Might Need to Know How to Measure Superheat and Subcooling

Knowing how to calculate superheat and subcooling (aka sub-cooling and subcooling) values is essential to ensuring proper refrigerant charge in air conditioning systems and refrigeration units. The measurements also assist in troubleshooting problems with the equipment. This is important because knowing superheat, subcooling and temperature difference (Delta) across a coil:

Allows an HVACR technician to ensure refrigerant levels are properly maintained for maximum efficiency and performance
Safeguards against improper diagnosis and repair such as diagnosing and replacing the compressor when the problem is something else. That’s a costly but very common mistake.

Tools and Specs to Keep in Mind

The primary tool for the job is a superheat/subcool meter or gauge. They’re produced by many brands in a price range from about $70 to $250. We suggest looking for one with presets for the refrigerants you work with most commonly – R22, R410a (Puron), R134a and R404a, for example. That eliminates the need for inputting the specific refrigerant’s specs.

A handy assistant when converting low-side and high-side pressure to temperatures is a phone app like Emerson’s Check & Charge. The free app is one of many great HVAC troubleshooting apps every tech should have. Its features include superheat (non-TXV) and subcooling (TXV) calculators for R22 and R410A. Check & Charge is available here for iOS and here for Android. A companion to it is the Danfoss Refrigerant Slider with pressure-to-temperature conversions for 80 refrigerants. Those are specs you must know to successfully evaluate the performance of the equipment you’re evaluating.

How to Measure Superheat and Subcooling

Here’s how to determine these values in a few easy steps for each.

Calculating superheat:

Measure the low-side pressure with your gauge.
Convert pressure to temperature with an app, slide or chart.
Next, take the temperature of the suction line where it leaves the condensing unit, though stay 4-6 inches from the compressor.
Use your measurements to determine the amount of superheat. For example, if suction line temperature is 65 degrees and your conversion of the suction pressure to temperatures yields 50 degrees, then the difference is 15 degrees of superheat.

Calculating subcooling:

Measure the high-side pressure with your gauge.
Convert pressure to liquid temperature with an app, slide or chart.
Measure the temperature of the liquid line where it meets the evaporator and before the metering device.
Finally, determine the difference in the temperatures determined in Steps 1 and 2 by subtracting the liquid temperature from the saturation temperature of the refrigerant you’re working with. A difference of 12-15 degrees is standard. For example, if your conversion of pressure to temperature yields 115 degrees for saturation and the liquid line temperature is 100 degrees, that’s 15 degrees of subcooling.

Note: Superheat should be 12-5 degrees in ambient air temperature below 85 and 8-12 degrees in warmer air. Subcooling should be 5-18 degrees, at the high end of that spectrum when the equipment has a TXV. Always go by the manufacturer’s specifications.

Using superheat and subcooling data in troubleshooting:

Low superheat: Too much refrigerant in the evaporator. It’s likely overcharged.
High superheat: Too little refrigerant in the evaporator. This might indicate that the system is low on refrigerant, but it’s just as commonly caused by insufficient heat getting to the evaporator (dirty filter or blower, undersized or blocked ductwork, plugged evaporator coil) or a dirty/defective metering device.

Caution Notes

Don’t try this at home! Diagnosing and repairing air conditioning and refrigeration is one of those jobs experienced DIY homeowners are wise enough to steer clear of. Moreover, working with refrigerant is not a DIY job unless you’re a licensed HVACR technician.

Only licensed techs can legally handle refrigerants. Additionally, overcharging and undercharging a system lead to serious issues with air conditioning and refrigeration equipment. There’s no reason to turn what might be a small problem into a major mechanical failure.

And here’s an important caution: Refrigerant might not be the issue. If you misdiagnose the cause of the problem, your solution won’t work. Consequently, the right approach is to leave the work to an experienced HVAC technician.

Hiring a Pro for your AC or Refrigerant Job

Finally, if this post interested you, it’s possible you ARE an HVACR pro. If so, we hope it was a good refresher in superheat and subcooling basics. We’d enjoy getting your feedback in the Reply box below. If you’re a homeowner diagnosing an AC or refrigerant issue, we’d recommend discussing the issue with a professional.As such, look for one certified by N.A.T.E., the North American Technician Excellence.

Day and Night Air Conditioner Reviews: Pros, Cons, Performance

December 28, 2017 by Sindy Aubrey

What all consumers should know when reading Day and Night air conditioner reviews is that Day and Night and Carrier, one of the most well-known AC brands, are both under the same parent company, which is United Technologies. So yes, they are considered competing brands, and although entirely different, some components may be similar as both brands undergo the same quality control procedures.

Day and Night HVAC

However, consider this write-up will focus entirely on Day and Night — what it offers, pros and cons, and if it’s the HVAC system you’re looking for.

Day and Night Air Conditioner Overview

Many Day and Night air conditioner reviews state that the brand’s line of ACs are mainly for residential use, but its models actually work in the light commercial market as well. Its line of air conditioners are all Energy Star certified and one can choose from 13 SEER models all the way to 19 SEER.

As of writing, Day and Night’s models include Day and Night Performance, Day and Night Constant Comfort, and Day and Night Constant Comfort Deluxe.

Day and Night Air Conditioner Technical Specifications

Resistant to corrosion
Has a warranty of 10 years (specific parts)
Single-stage compressor
Has a noise range of 70 Db
13 to 16 SEER

Day and Night Constant Comfort

Wi-Fi enabled
Has a warranty of 10 years (specific parts)
Includes a limited replacement warranty of five years
Resistant to corrosion
Single-stage compressor
13 to 16 SEER

Day and Night Air Conditioner Technical Specifications

Has a warranty of 10 years (specific parts)
Includes a limited replacement warranty of 10 years years
Wi-Fi enabled
Has a noise range of 66 to 70 Db
Double-stage operation
Resistant to corrosion
17 to 19 SEER

What most Day and Night air conditioner reviews fail to note is that the company is very vocal about its Matching System, wherein it assesses the hotspots in your home. This will create product combinations to bring out the maximum comfort and at the same time operate in a way that homeowners won’t have to pay for extremely pricey monthly bills.

Authorized dealers may also be of help and can guide would-be buyers on which Day and Night air conditioner currently suits the environment of the house. It should be noted that Day and Night offers heaters as well, and most of its cooling systems are often work better if paired with the company’s gas furnaces.

PROs and CONs of Day and Night Air Conditioners

PROS

Some models include a limited warranty of 10 years on all parts, of which includes the compressor
Almost all models can match with the brand’s own heating equipment to make the HVAC system more efficient
Select cooling systems can be accessed remotely via Wi-Fi
You can choose between single-staged and double-staged fan motors
The brand’s system has a modulating operation of up to five stages
Day and Night air conditioning systems operate quietly

Day and Night air conditioner reviews claim that its entire line of products are run tested each to offer homeowners an energy efficient cooling systems, as well as heating systems. The company also offers warranties, or what it calls “No Hassle Replacement™” that promises replacement of parts, including the compressor, should it malfunctions.

However, owners of a Day and Night airconditioning unit should be aware that it should be registered first. If not, the warranty period will be cut to five years instead of 10. The company provides a certificate for each unit purchased.

CONS

Select units with two-stage compressors have the tendency to malfunction in the long run

Two-stage systems obviously cost more than those with single stage compressors. Because of the complexity of the technology itself, homeowners would likely find it difficult to maintain their systems. Moreover, the additional cost of double-stage compressors may not be ideal for homeowners with small homes. Typically, one stage systems are enough to make the whole area cooler.

Most Day and Night air conditioner reviews note that problems encountered with Day and Night systems are a result of improper installation. Given all products have drawbacks of their own, consumers must be wary of HVAC technicians who aren’t totally cut for the job. People tend to go with the most affordable technicians they can find, only to end up with an improperly installed Day and Night air conditioner. Make sure you get the best contractor as it will actually help you save more in the long run.

Things to Consider Before Purchasing a Day and Night Air Conditioner

With technology improving each day, consumers now have the option to purchase AC units integrated with intelligent cooling technology. Day and Night units use SmartSense technology. This will enable air conditioners to adjust the temperature automatically no matter what the weather is. Alternatively, SmartSense allows owners to adjust home temperatures remotely, so whenever you’re away, you can still adjust your home settings using your very own smartphone.

Day and Night air conditioner reviews also praise the company’s low noise models. Its AC units are so quiet; homeowners will only hear the fun running, leaving their sleep undisturbed even in high-level settings.

What’s important is, the AC unit needs correct installation in order to deliver the optimum performance without using too much energy.

Day and Night HVAC Conclusion

Day and Night air conditioner reviews overall rate the brand’s equipment a quality product. Sure there are negative reviews, but these mostly come from users who had their units not put up properly. The company is quickly becoming a competitor against other more favorite brands. Its line of HVAC systems isn’t exactly what you commonly see in households.

However, it won’t take long before people start switching.

Perhaps the lack of back up from a big name contributes to its seemingly “unknown” status, as only a few people know it has the same parent company as Carrier.

Do you own a unit from the brand? It would be great to hear some Day and Night air conditioner reviews from yourself, based on your experience. Or, tell us what you think of its AC units below.

Basic: Performance Series (7 models, 13-16 SEER);
Better: QuietComfort Series (3 models, 13-16 SEER);
Best: Deluxe Series (2 models, 17 & 19 SEER).

Our goals are to assist you in selecting an AC that fits your efficiency and performance needs. We also aim to help in deciding if an AC/furnace system or heat pump system is a better option for your specific heating and AC requirements.

Tempstar Air Conditioner Technical Specs

The specifications are where we learn about efficiency and performance to find the best one for our application.

The Deluxe 19 TVA9 is Tempstar’s AC with a variable-speed compressor that modulates between 40% and 100% to deliver just enough cooling to keep your home’s temperature precisely on the thermostat set point (think cruise control);
The Deluxe 17 (TCA7) is Tempstar’s only 2-stage model. So, it runs on low capacity (about 65%) most of the time for quieter cooling with little temperature fluctuation;
The other 10 models are single-stage ACs that run at full capacity with performance that is loud. It also creates slight temperature swings and does not reduce humidity as well as 2-stage and variable-speed models;
Deluxe Series models and the QuietComfort 16 (TSA6) are Tempstar’s only Energy Star-certified models;
Deluxe and QuietComfort Tempstar air conditioner models are supported by the brand’s Wi-Fi Observer control. It allows remote monitoring and adjusting. This is even though Tempstar ACs can work with any brand thermostat that matches single-stage or stage cooling;
Noise limits range from 56dB in the Deluxe 19, considered comparatively quiet, to 76dB in the Performance 16, considered significantly louder than average.

PROs and CONs of Tempstar Air Conditioners

Tempstar Air Conditioner PROS

You have fair efficiency and performance options with the lineup from 13-19 SEER and single-stage, two-stage and variable-capacity units;
Tempstar offers warranties that are well-above the industry average. This includes many with 5-year or 10-year unit replacement coverage that provides for a complete new AC/condensing unit if the compressor or coil fail in that time;
The two-speed fan motor on Deluxe models runs more quietly and more efficiently than single-stage fans do;
The Performance 14 NH4A4 Tempstar air conditioner is a compact model ideal for installation in multi-family housing. They also work in residences where distance between houses is narrow and other space-limited locations;
The Performance 13 N4A3**C is durably built and coated for the demands of harsh, seaside climates. But since its efficiency is just 13 SEER, it is not a good fit for warm, humid locations;
Powder-coat finishes are durable and they resist to fading and scratching;
Soft-mounted compressors on Deluxe and QuietComfort Tempstar air conditioner models reduce compressor startup noise;
The four units compatible with the Observer wall control are ideal for those with variable, unpredictable schedules who want the convenience of controlling their HVAC system remotely to reduce energy use and make sure their home is comfortable when they arrive;
Tempstar has a national distribution system, so replacement parts and entire units are readily available throughout North America;
Any professional HVAC technician can service these units.

Tempstar Air Conditioner CONS

The most efficient unit, the 19 SEER TVA9, is significantly less efficient than top models from Lennox (XC25 – 26 SEER), Maytag (PSA4BI – 25.5 SEER) and Amana (AVXCO – 24.5 SEER). So, it isn’t the best choice in climates with extreme heat;
There are 12 Tempstar air conditioner models. Yet, only the top two offer staged cooling with little performance or efficiency difference between the bottom six units;
Air conditioners with sound levels of 74-76 decibels are loud. Six Tempstar ACs are in that range;
Tempstar air conditioner models have competitive prices. But, like most brand ACs, they are only sold through registered dealers. Sp, it requires getting a written estimate to know what the total installation cost will be.

Things to Consider Before Purchasing a Tempstar Air Conditioner

The first consideration is whether a central AC is the right choice for you. In very warm climates where heating is rarely necessary, a heat pump and air handler might keep energy bills lower throughout the year. In very cold climates, a heat pump and gas furnace dual-fuel system is the best path to low energy bills. Tempstar heat pumps are dual-fuel compatible.
If you’re replacing just the AC, then consider efficiency. The warmer and/or more humid your summers are, the higher the unit’s efficiency should be. The one exception might be if you are moving soon and don’t want to pay more for an AC you won’t use for long. But remember that smart buyers will want to know the AC’s efficiency. A very efficient Tempstar air conditioner can be a selling point.
Finally, make sure your AC contractor installs the right size air conditioner. If your home’s insulation, doors or windows have been through an upgrade since the last AC installation, the replacement Tempstar air conditioner should probably be smaller than the last one. A unit that is too large wastes energy. It can also cause temperature swings by over-cooling the space.

Don’t Forget Quality Installation

Many rigorous tests of air conditioners on the market show that most leading brands, Tempstar included, perform well when after a proper installation. A careless and imprecise process and setup can cause even the very best ACs to run poorly and have mechanical issues early. Get estimates from several local AC companies with a good reputation. Also, make sure the installers are certified, experienced and insured and that their work is backed by a warranty.

Amana Air Conditioner Reviews: Pros, Cons, Performance

June 8, 2017 by Sindy Aubrey

Our Amana AC guide is your one-stop place to research for the right Amana central air conditioner. Then, you can decide if the brand is a good choice for your residential or commercial space. The information below allows you to browse Amana air conditioner performance with technical specification and top units in each class.

Amana AC pros and cons offer insight for comparing this brand with others we’ve reviewed. Our reviews include Goodman, Bryant, and Carrier.

Amana Air Conditioner Brand Overview

George Foerstner designed and started manufacturing a beverage cooler in Amana, IA, in 1934. His company grew into the Amana Corporation and enjoyed decades of innovative productivity. Some examples are the first upright freezer and first side-by-side refrigerator. In 1997, Goodman Manufacturing acquired Amana. The company maintained it as a separate brand but with a nearly identical product lineup to Goodman’s.

The next chapter began in 2014 when global HVAC giant Daikin acquired both brands. Currently, the Amana air conditioner lineup is being upgraded to make Amana/Daikin one of the top five to ten brands in the industry. This places them alongside Trane/American Standard, Carrier/Bryant, Maytag/Westinghouse and Lennox. Goodman remains the leading budget brand of HVAC equipment.

Amana Air Conditioner Technical Specifications

The eight Amana air conditioner models perform well in three classes:

Base Amana ACs: These single-stage air conditioners with SEER ratings for efficiency between 14 SEER and the top pick in this series, the 16 SEER Energy Star-qualified Amana ASX16 central AC;
Better Amana air conditioners: The ASXC16 with 16 SEER efficiency and the ASXC18 with 19 SEER efficiency, contain a two-stage scroll compressor for low-capacity/high-capacity cooling. This tool is quieter, reduces humidity better than single-stage models and improves temperature balance;
The Amana AVXC20 is the best Amana air conditioner currently available. It has an outstanding 24.5 SEER rating made possible with the inverter technology compressor. The compressor runs at variable speed like cruise control with slight modulations. It aims to deliver precise cooling and premium dehumidification;
Both Amana two-stage models and the variable speed AVXC20 are wired for an Amana ComfortNet Communications thermostat. This is a $500 upgrade that synchronizes system components to ensure the best possible performance and efficiency;
As with all brands, superior efficiency and climate control go hand in hand. This is because the longer, slower cycles of two-stage and variable-capacity compressors make the best use of energy too.

Pros and Cons of Amana Air Conditioners

With the acquisition by Daikin, Amana is once again an industry leader. Here are reasons to consider Amana and a few potential disadvantages too.

Amana AC Pros

The range of models in price, performance and efficiency create options for homeowners in all climates;
Try replacing an old AC with a 19 SEER Amana ASXC18 or the 24.5 SEER Amana AVXC20. Then, you’ll get eco-friendly cooling that will cut energy costs up to 60%;
The 24.5 SEER efficiency of the AVXC20 is in the top three of all models with the Lennox XC25 (26 SEER) and Maytag PSA4BI (25.5 SEER);
Amana air conditioner models that qualify for Energy Star might also be eligible for energy rebates. So check with your local unity company or look for local rebates;
Amana warranties are among the very best in the industry. They include a complete unit replacement warranty, covering the compressor on the top models;
Even the base models ANX13 and ASX13 have 10-year warranties. All this time, base models from top brands like Carrier come with 5-year warranties and a higher price. That makes Amana a very good value;
Amana air conditioners consistently receive verified user ratings above 90%, often as high as 98% recommendations.

Amana AC Cons

The upgrade to Amana products has happened in the last few years. So if you choose Amana, make sure the equipment you receive was made in 2016 or later. This way you also ensure you’re getting a superior AC or complete HVAC system;
As of this writing, none of the Amana control/thermostats are Wi-Fi enabled for controlling your system remotely using your phone and an app. But there are Wi-Fi thermostats like the ecobee3 and the 3^rd generation Nest thermostat that support Amana systems;
With the upgrade in the quality of the Amana air conditioner lineup, it is likely that prices might rise and costs will be higher. But Goodman’s lineup that Amana was once identical with should remain a best seller in the low-cost HVAC market niche;
There might be some early confusion about Amana’s old and new units. This is because the newer models need Daikin replacement parts, not the old Amana parts. But the confusion should be cleared up within the first few years. Also, new ACs shouldn’t require much service anyway.

Things to Consider Before Buying an Amana Air Conditioner

Efficiency: The hotter and more humid your climate is on this Climate Zone map and/or the longer you plan to stay in your current home, the more cost-effective it is to buy a very efficient Amana air conditioner. It can be the 19 SEER ASXC18 or the 24.5 SEER AVXC20. In cool climates where running the AC is an occasional need, a moderately efficient model like the ANX13 or ANX14 cost less compared with more efficient models.
Eco-friendliness: If minimizing your environmental impact is important to you, then buy the most efficient AC model you can afford. Keep it maintained to run as efficiently and durably as possible.
AC vs. heat pump: ACs come with gas or oil furnaces, most of the time. But did you know that a heat pump is a more efficient way to heat than even an efficient gas furnace? And heat pumps provide air conditioning too. If you’re buying the equipment for new construction or are replacing an entire HVAC system, talk to your HVAC contractor about heat pump or dual fuel heat pump options.
AC size: If you’ve added insulation or upgraded windows with energy-efficient glass, your replacement AC probably doesn’t need to be as large as the old one. It also shouldn’t be so. Talk to your contractor about doing a Manual J load calculation to accurately size the unit.

Choosing and Cooling

The best way to get a quality Amana air conditioner properly installed is to request estimates from three of the top HVAC companies in your area. Look for an experienced installer that is licensed, insured and has a proven track record of quality installation and excellent customer service.

We make HVAC research easy, and we hope it’s been interesting too. If your friends and followers might be researching an AC or HVAC system for their homes, perhaps they’d benefit from you sharing this Amana AC guide with them!

Mitsubishi Air Conditioners Review: Pros, Cons, Performance, Top Picks

March 17, 2017 by Sindy Aubrey

This Mitsubishi air conditioners guide includes information that will assist you in researching a ductless AC system for your home or commercial space. Performance and technical specs are included for comparing Mitsubishi ductless air conditioner models to one another and to other top brands See our reviews of Trane air conditioners and Rheem air conditioners for comparison. We have also reviewed ductless Mitsubishi heat pump systems and the recently released ducted Mitsubishi AC and heat pump systems.

Mitsubishi Electric is known globally as an innovative producer of technology including HVAC equipment. It has been one of the pioneers in ductless heating and cooling. The Mitsubishi company was founded in 1921 in Japan and split into several companies after WWII. Today, Mitsubishi Electric has its headquarters in Tokyo with offices in Asia, Europe and the Americas.

Mitsubishi Air Conditioners Brand Overview

Mitsubishi remains the world leader in ductless systems. These split systems are often called mini-split systems because both the outdoor condensing units and indoor air handlers are smaller than those of standard ducted split system components.

The AC-only systems include an outdoor condensing unit and one indoor unit installed on the floor, wall or ceiling. Each indoor unit cools a single room or zone. Refrigerant is carried from the condensing unit to the indoor unit where it captures heat. Then it carries it outside and disperses it through a radiator-type coil, effectively cooling the air indoors.

Mitsubishi AC Technical Specifications

Reviewing the specifications of Mitsubishi air conditioners is made easier by dividing the equipment into outdoor units (condensing units) and indoor units.

No products found.

Mitsubishi air conditioners outdoor units:

13 Mitsubishi condensing units are manufactured with capacity ranging from 9,000 BTU to 42,000 BTU. By contrast, ducted split system condensing capacity ranges from 18,000 to 60,000 BTU.
Model MUY-GL09NA-U1 is the top pick for efficiency at 24.6 SEER. But it is the smallest too at 9,000 BTU, and it is suitable for one small room such as a bedroom.
Efficiency of Mitsubishi air conditioners drops with size. So the Mitsubishi PUY-A42NHA6 is 42,000 BTU, but it just has 14.4 SEER efficiency.
Sound level of outdoor units ranges from 48 decibels to 55d decibels compared with about 65 to 75 decibels for ducted split system ACs, and capacity of the outdoor unit is not.

Mitsubishi air conditioners indoor units:

Upfront note: Unlike ducted split systems that have one outdoor unit and one indoor unit, split system outdoor units support up to four indoor units. And the total BTU capacity of indoor units must match the capacity of the outdoor unit. For example, a 36,000 BTU outdoor unit can be installed with one +/-36,000 BTU indoor unit, two indoor units of +/-18,000 BTU, four indoor units of +/-9,000 BTU units or another combination that adds up to +/- 36,000 BTU.
Floor-mounted units are made in four sizes from 9,000 BTU to 18,000 BTU.
All four floor-mounted indoor units include 5-speed fans for comfortable cooling.
There are currently more than 40 wall-mounted indoor units ranging in capacity from 9,000 BTU for a small room to 34,200 BTU for a large room or open floor plan zone.
Wall-mounted units are available in one style and three colors: white, black and silver.
Wall-mounted indoor unit fan speeds range from 3-speed to 5-speed. It has sound levels as low as 19 decibels on smaller units and up to 40 decibels on larger units.
MSY series indoor units are cooling-only. PKA and MSZ series indoor units accommodate both Mitsubishi air conditioners and heat pumps.
Top picks are the MSZ-EF series wall-mounted indoor units with 17,200 BTU capacity cooling and 5-speed fans for optimal comfort.
Ceiling-cassette indoor units install in the ceiling. So they are ideal for drop-ceiling locations and use where a low profile is desired.
Nine ceiling-cassette units are offered in the SLK 3-speek series and the top-pick PLA 4-speed series with capacities from 8,400 BTU to 42,000 BTU.
All cassettes accommodate both Mitsubishi air conditioners and heat pumps.

Pros and Cons of Mitsubishi Air Conditioners

Mini-split, ductless systems from Mitsubishi have their advantages and disadvantages compared with competitors and other HVAC system types. Here are pros and cons to consider and compare to other brands.

Mitsubishi AC Pros:

Mitsubishi air conditioners are considered among the most durable and reliable ductless units available;
The efficiency of the smaller units, up to 24.5 SEER, is excellent;
Old ductwork allows up to 25 percent loss of cooled air, but that is not a factor with ductless AC;
Ductless systems are ideal for retrofitting areas where installing ductwork isn’t a practical option;
Ductless systems are easier and less costly to install than ducted systems;
The large variety of indoor units gives you style options and installation flexibility;
Because Mitsubishi air conditioners are a popular brand, it is easy to find parts and service.

Mitsubishi AC Cons

As a reminder, these are Mitsubishi air conditioners, so they are not suitable for locations that require heat too. See our Mitsubishi heat pump reviews for AC/heating systems!
The mid-size and large-capacity Mitsubishi air conditioners offer SEER efficiency ratings that are mediocre compared with the best standard split system air conditioners from Trane, Lennox, Carrier and other top brands.
While ductless outdoor units are relatively quiet, these systems require that an indoor unit with a fan in each room or zone. There might be more noise in the immediate area than a standard split system would produce.

No products found.

Things to Consider Before Purchasing a Mitsubishi AC

The first and obvious issue to consider is whether you need AC only or both AC and heating. These Mitsubishi air conditioners are for installation in:

Very warm climates;
Summer homes where heating isn’t necessary;
Locations without AC or where the existing air conditioning isn’t adequate.

If you already have duct work, installing a conventional split system is probably a more cost-effective choice. This is especially true if you have a large home. This is because the largest of these Mitsubishi air conditioners is 42,000 BTU, only enough cooling capacity for a home of approximately 2,000 square-foot and in a warm climate.

Are You Going Ductless?

Ductless systems are growing in popularity due to their flexible installation options, competitive cost and good energy efficiency. Are your family and friends considering going ductless? It should be one of their options, so consider passing this information on to anyone who might appreciate the information.

All You Need to Know about Current Home Energy Efficiency Standards

February 22, 2017 by itadmin

Living with Home Energy Efficiency

Home energy efficiency is essential in today’s eco-conscious world and there is little inside a residential property that does not come into play, toward creating more energy efficient homes. From light bulbs to water heaters, from home appliances to the way a home is insulated, energy savings always start in the home and they always lie in the details. According to the U.S. Department of Energy, a home uses 42 per cent of its total energy expenditure on space heating, 18 per cent on water heating, 6 per cent for cooling the home, 5 per cent for lighting and refrigeration (each), while the remaining 24 per cent is spent on other uses. This is why regular home energy audits are important and why they can dramatically improve any home’s energy savings standing.

What makes a home energy efficient?

According to the generally accepted energy efficiency definition, a home is efficient in terms of energy expenditure, when its occupants actively manage and maintain energy consumption levels. The more energy efficient a residence, the more performance and services it manages to deliver, for the less energy consumption. The Office of Energy Efficiency & Renewable Energy (EERE) with the U.S. Department of Energy designs, improves, and enforces energy-efficient standards and technologies in several aspects that relate to home building and ownership.

Home building efficiency. The EERE runs several research and development plans, as well as a host of market stimulation plans, such as Building America and the ENERGY STAR approach to building homes as a whole. It also awards homes an energy score, which gauges their overall energetic performance, encourages students to develop energy efficiency programs and designs, and enforces residential energy building codes.
Lighting standards. The Office is currently working to promote LED lighting better and to make sure the facts circulated about this technology are accurate. At the same time, it is encouraging the use of SSL (solid state lighting), which may one day cut down nationwide energy consumption levels to half their current values.
Equipment and appliance standards. The Building Technologies Office of the EERE is already enforcing energy savings standards for some 50 discrete categories of equipment and appliances. Thus far, this has resulted in saving some $55 billion on power bills in 2014 alone. The office projects that the amount of money saved from 1987, when the standards first came into effect, until 2030, will surpass $1.7 trillion.

What is energy conservation?

Energy conservation is closely tied in with energy efficiency. It is a concept that stems from physics, as the energy conservation definition illustrates. In terms of the home use of energy, conservation refers to cutting down on the amount of power used, by saving energy, reducing waste, and making sure the energy available is used rationally.

Nowadays, with several programs across the country aimed at improving energy consumption levels in the residential segment, it’s actually not that difficult to create a tailored energy conservation plan for your own home. For instance, best practice recommendations from the University of Colorado state that an occupied house can reach its maximum energy efficiency when its thermostat is set at 68 degrees Fahrenheit. The same recommendations advise against installing a central A/C system, save for the situation in which the whole house requires cooling down. Other tips include recycling old appliances and having them replaced with newer ones, which observe ENERGY STAR standards. Finally, if you’re thinking of building yourself a home, or of purchasing a new residential construction, you shouldn’t underestimate the potential of sun-tempered homes. By using passive solar energy, a super-insulated home of this type stands to cut down your energy consumption levels by up to 40 per cent.

Here are some other useful tips for homeowners interested in devising a customized energy conservation plan:

Thermostats should be set back during the night (by some 8 F) or when the house is not occupied for 24 hours (down to 50-55 F);
Unused rooms can be heat-sealed by keeping their doors, windows, and heat registers closed.
Heating systems need to be regularly cleaned, with filters replaced about once a month during the months when heating systems are in use.
Hot water leaks and other losses can also render a home less energy efficient. As such, owners should make sure none of their faucets are leaking and have low-pressure shower heads installed. Make sure the water temperature on your washing machine is set to an appropriate level and invest in an ENERGY STAR water heater.
Refrigerators should be set to 35-40F, with freezers at 0-5F. Don’t hold fridge doors open for too long and keep ice buildup levels in the freezer down to an absolute minimum.
Reduce the intensity of any gas cooker to the point where the flames are blue instead of yellow.
Only run the dishwasher when it’s full and let them air dry in there. Newer models no longer require that you rinse the dishes before washing them.

Best Central Air Conditioner Prices

September 6, 2016 by Sindy Aubrey

When looking for a new central air conditioner, it’s important to know that the lowest central air conditioners prices are not necessarily the best prices. In fact, pricing should be among the last criteria on your list. Here’s what to focus on when buying a central air conditioning unit, and how each aspect influences the pricing of said unit:

Central Air Conditioner Prices: Why the Big Differences?

Central air conditioner units prices start off at about $800 for a new appliance and can go well beyond $10,000. This means installation and any additional work will increase the overall cost. Although the price range is extensive, it’s not unjustified. The most important variables when talking about central air conditioners prices are capacity, efficiency, and brand. Here’s a breakdown of the costs involved in acquiring and installing a new central air conditioner:

Central Air Conditioner Prices by Brand

Here are the most popular central air conditioner brands and their lowest, highest, and average prices:

Brand	Lowest Price	Average Price	Highest Price
Rheem	$1,000	$1,500	$3,700
Bryant	$900	$1,300	$3,900
Amana	$1,100	$1,600	$3,200
Lennox	$1,200	$1,800	$3,800
Trane	$1,300	$2,000	$16,000
Carrier	$1,500	$1,900	$3,900
Goodman	$1,100	$3,100	$8,000

Note: These prices only refer to the central air conditioner unit; Installation costs are not included in the examples above.

As you can see, the price range is considerable for many manufacturers. The lowest price usually refers to the small, less efficient, and usually, older models that are still available for sale. The highest prices are those of new appliances that feature the highest efficiency ratio and the most powerful compressors.

Even though the manufacturer is an important criterion when looking for a new central air conditioner, it is not the only one to matter. Capacity and efficiency are critical aspects that need to be taken into account when looking for a new central air conditioner.

Central Air Conditioner Prices by Capacity

Generally, the climate zone you live in determines the capacity of your future central air conditioner unit. However, the area of your home is a decisive factor, too. Here are the average prices for different central air conditioner units in terms of capacity:

Central Air Conditioner Capacity	Average Price
1 Ton (12,000 BTU)	$900
1,5 Tons (18,000 BTU)	$1,200
2 Tons (24,000 BTU)	$1,300
2.5 Tons (30,000 BTU)	$1,400
3 Tons (36,000 BTU)	$1,500
3.5 Tons (42,000 BTU)	$1,700
4 Tons (48,000 BTU)	$1,800
4.5 Tons (54,000 BTU)	$2,000
5 Tons (60,000 BTU)	$2,300

Note: 1 ton = 12,000 BTU (British Thermal Units) = the amount of energy it would take to melt 1 ton of ice in 24 hours. To put things in perspective, a 12,000 BTU central air conditioner will be able to cool off about 500 square feet.

When buying a central air conditioner, it’s important to accurately match the unit’s capacity with the space it needs to cool off. An appliance that is too weak will obviously not be able to provide a comfortable temperature during summer months. However, one that’s too strong will cycle on and off every few minutes, thus becoming inefficient. In addition, given it will not work permanently, it will not be able to control the air humidity – an important factor when it comes to your comfort.

Central Air Conditioner Prices by Efficiency

The most efficient central air conditioners are usually the most expensive, but they are the cheapest to run. Therefore, the cheapest appliance is not always the best one for long-term use. in fact, efficiency should be among the first things to take into account when looking for a new central air conditioner. Here are the average prices for central AC units in terms of efficiency:

SEER (Seasonal Energy Efficiency Ratio)	Average Price
<14 (Low)	$1,250
15-17 (Average)	$1,800
18-20 (High)	$2,200
21-24 (Highest)	$2,900

No matter their efficiency ratio, central air conditioners can be heavy consumers – especially if you live in warm or hot areas. At the moment of writing, the U.S. government offered a tax credit of about $300 for those who purchase central air conditioners that comply with Energy Star rules and have a SEER of 16 or more.

The highest efficiency central air conditioners are the best for our environment: They use significantly less energy and produce fewer greenhouse emissions. However, when it comes to our wallets, things are not that simple. There’s a fine balance between efficiency and overall costs, balance that mainly depends on the following factors:

How much and often you will use your central air conditioner.
How well insulated your home is.

For example, if you live in the northern part of the country and only use the central AC 2 or 3 months per year, sending more than $3,000 for a highly efficient appliance will not make as much sense as spending $2,000 for an average efficiency one. On the other hand, if you live in Southern California, a highly efficient central AC is the best way to go – but only if you have proper home insulation.

Extra Costs of a Central Air Conditioner Unit

The following initial expenses might save you more in the long run:

A Thermostat

A programmable thermostat is one of the easiest and most efficient ways to reduce energy consumption in your home. It can cost anywhere from $20 to $400, but will pay for itself in a month or so. A thermostat adjusts the activity of your central air conditioner based on a pattern inputted by you.

Extended Warranty

If you feel the manufacturer’s default warranty is not enough, you can invest in extending it. Default warranties usually last between 8 and 15 years, with an average of 10 – 12 years. Many sellers offer 1, 2, or 5 extra years of warranty for a few dozens or hundreds of dollars. This is particularly important for those who live in warmer climates since the appliance will be used more frequently.

Keep in mind the lifespan of a central air conditioner unit depends on how often you use it. The average lifespan of 10 years that most manufacturers promise refers to temperate areas where the appliance is used a few months per year. If you live is warmer climates with high humidity, or by the ocean where the air is saltier, your central AC is likely to last about 8 years or less.

Extra Functions

Most central air conditioners today come with a humidity control function. However, other features might be desirable for some customers. Quiet operation functions can be extremely useful for small homes or for those where the outside unit is placed near the bedrooms. Multistage compressors are another desirable feature in central ACs. They can significantly lower your energy bills and extend the appliance’s lifespan.

Central Air Conditioner Prices: Installation

Installation costs alone for a central air conditioning system range between $350 and $8,000 for a new appliance. Here’s the breakdown:

Delivery costs: Completely depend on each retailer.
Materials & supplies: Between $50 and $150 if your home already has ducts and they are properly insulated.
Contractor(s): Between $300 and $2,000, depending on the amount of work needed to install the central AC unit. Some appliances can be installed in just a few hours with minimal effort, while others require extensive work. Under no circumstances should you install the central AC unit by yourself. This is a complex project that involves handling refrigerant, high-voltage electricity, and sensitive electronics – not to mention the environmental concerns that come with improper
Ducting: Between $400 and $3,500, mainly depending on the size of your home.
Insulation: Between $450 and $3000, depending on how many ducts you have in your home.
Debris removal & cleanup: If you do not want to do this by yourself, be prepared to pay $100 at most for these services.

Some high-SEER central air conditioners will also require solar panels to keep the energy consumption to a minimum. Therefore, you might need to be ready to invest in these, too.

How to Find the Best Central Air Conditioner Prices

As mentioned before, the lowest price rarely is the best price. Here’s how to effectively find the best central air conditioner price and contractor:

Ask yourself how long you plan on living in this house. If you are not sure, installing an expensive appliance might not be the best idea.
Always check for references and read reviews for contractors.
Ask recommendations and quotes from at least 3 professionals. Analyze what they have in common – ideally, they should have identical or similar capacities. Then, analyze their differences and see which ones matter the most to you. Maybe a certain model has an extensive warranty, while another is highly efficient. Use what you read in our article to decide which will fit your needs.
Do not cheap out, but don’t go above your budget either.

Central Air Conditioner Prices Recap

All in all, installing a new central air conditioner will cost between $2,000 for small homes or apartments and $15,000 or more for large homes. Given the significant number of variables that decide the central air conditioner prices, it would be impossible to give a more accurate response.

Air Conditioning Service, Repair, and Maintenance – All You Need to Know

August 2, 2016 by itadmin

Choosing the Right Air Conditioning Service: Comfort or Misery

The air conditioner is a vital part of our homely existence. It has multiple functions that keep us happy and comfortable, which include cooling, heating, dehumidifying, and cleaning the air of possibly dangerous particles. Therefore, when it breaks down, immediate action must be taken, to ensure it’s back on track in no time. But how do you do it? Do you do it yourself or do you use the proverbial ‘call a guy’ method? If you’re not quite sure what to do, this article will definitely help you. Moreover, we have also listed some top tips and tricks to maintain your AC unit, apart from fixing it.

What does actually go wrong with an AC unit?

As opposed to furnaces, which are quite simple, AC units are complex pieces of equipment. This means they require a whole array of conditions to work properly. For example, they need to have a certain size, so as not to hang too heavy on the house. They must also have a certain volume of refrigerant, also known as the ‘charge,’ they need a certain amount of air to flow through the coils and many other criteria that need to be met. When one of these criteria is not met, the entire system will suffer.

Here are some examples of things that may go wrong with your AC and what causes them.

if you generate more heat indoors than you normally do, because you are having a party and there are a lot of people in the house or because you’ve plugged in a high number of appliances at the same time, the AC will not be able to keep up
if the refrigerant leaks out, evidently the AC will not have the same power to cool the air anymore
if airflow across the condenser reduces, so will the AC’s ability to reject heat outdoors. Yet again, its capacity to keep up when the load increases will diminish, especially when confronted with high outdoor temperatures
the same problem occurs in dry climates, only with the indoor (evaporator) coil. A low airflow hurts it.
In humid climates, the problem tends to become more complex. When the airflow is high, there will be less humidification, which will lead to high indoor humidity. But, if the airflow gets too low, the evaporator coil will actually freeze. Not only will this make the AC’s performance drastically decrease, but its compressor can fail. This means you will have to seek help to repair it, and it will not come in cheap.

Air conditioning repair and service – how to do it yourself

If you’ve decided not to ‘call a guy’ and tackle the AC repair yourself, it’s best if you start by doing some research. To help you with that, here are some DIY AC repair and service projects you can try at home and all the ins and outs to help you make them successful.

#1. Cleaning the AC in the spring

This is one chore you’ll be grateful you performed. Not only will you be more comfortable in using you AC afterwards, but you will also pay less on your cooling bills. There are three ways in which you can clean the AC.

Method 1 – Cleaning the indoor unit of an AC

Turn off the power towards your furnace or blower. If you can’t find the switch, turn it off from the main panel or unplug it.
Replace the air filter. Make sure you consult the manual before you buy a new one, to make sure it’s the right size.
Vacuum all the visible dust, hair, and debris in the blower compartment.
If the motor is equipped with lubrication ports, pour a few drops of oil into it, according to the manual specifications.
Check to see if any algae have grown in the condensation tube. If so, remove them and pour a solution made of bleach and water into it.
Clean the drain tube using a brush with small bristles
Hook the drain line back to the unit and restart it carefully.

Method 2 – cleaning the outdoor unit of an AC

Shut down the power at the shutoff box which should be located on the exterior of your house. If there is no visible shutoff box, turn off the circuit breaker which normally powers the AC. Either way, the appliance needs to be turned off completely, to avoid it starting unexpectedly and causing accidents.
Vacuum the condenser fins using the attachment that has a soft-bristle brush. Make sure to check for any debris or gunk that might be trapped in there, such as leaves, grass or weeds. Also, trim all the greens surrounding the box, so that it’s completely free on a 2 feet radius.
There should be a grille on top of your AC, which you need to unscrew and take off. You will notice the fan lifts even without it, so be careful not to damage the electrical wires. Gently clean the fan with a damp cloth.
Should your fan have lubrication ports, pour a few oil drops into it. Make sure the oil is specially made for electrical motors and not regular oil.
You can also clean the empty unit from the inside out, by lowering a water hose in it and lightly spraying it.
Re-assemble everything together and screw the lid back on.
Disable the AC by going inside the house and switching it from ‘cool’ to ‘off’.
Allow it to sit idle for 24 hours so that it has time to dry out completely.
Restart it and wait at least 10 minutes for it to start working again.
Check to see if it works correctly.

Method 3 – cleaning a room AC

Just like for the other two, you need first to unplug the room AC or turn off the breaker that leads to that circuit.
Remove the appliance’s rear exhaust panel and clean all its fins and coils with the soft-bristled brush of your vacuum cleaner.
Remember to check the drain channels for clogs. They are usually located at the bottom of the AC. Should you find any clogs, clean them with a pipe cleaner.
Remove the ACs front grill, take out the filter and clean it. You can do so by either vacuuming it or washing it with some sudsy water, lukewarm. Before you reattach the filter to the unit itself, make sure it has completely dried off.
Power it back up

Maintaining your AC

As far as central air maintenance goes, the old saying does prove to be correct once more – it’s better to maintain it than having to fix it. There is a whole array of things you can do to make sure it keeps running as smoothly as when you bought it. These things, if done correctly and at regular intervals, will not only help your AC not breaking down but will save you energy as well. Therefore, here are the most important things you can do to maintain your AC.

Arguably the most important task you need to perform is to clean regularly the ACs filters. It will ensure it keeps on running efficiently, because a dirty or clogged filter blocks the normal air flow and forces your AC to run twice as hard, overheat and, sometimes, malfunction.
Also, replacing a dirty filter will lower the unit’s energy intake by 5% to 15%. Filters need to be replaced every one or two months, but you may need to do it more often if there is an infant or a pet in the house.
Cleaning the evaporator and condenser coils is important as well. They collect an incredible amount of dirt over the years which insulates the coils and reduces their ability to take in heat. Therefore, the coils need to be checked and cleaned every year. The time between cleanings can be even longer, seeing as the filters, if clean, normally trap all the dirt and dust before they reach the coils.
Clean the coil fins. The evaporator and condenser coils have some fins that can easily be clogged by debris or get bent. If so, they will block the airflow that should normally run through the coils. Use a ‘fin comb’ to comb them back into their original position.
Clean the unit’s drains by inserting a stiff wire through them from time to time. If they are clogged, they will stop the AC from absorbing humidity. In turn, this might discolor your walls and carpets and produce condensation.
Cover the outdoor part of your AC in the winter to protect it from the bad weather and debris flying around.

Hiring a professional to manage the central air conditioning repair service

In case you do not wish to turn fixing and even maintaining your AC into a DIY job, you can always hire a professional. In terms of central air service, here’s what he or she should do.

Check if the unit has a sufficient volume of refrigerant
Test said refrigerant for any leaks that might damage the unit
Capture all the refrigerant that escapes the unit and not release it into the environment, as that is illegal
Check to see if there are any seal duct leakages in the central system
Check the evaporator coil by measuring the airflow that passes through it
Inspect all the electrical terminals, apply a non-conductive coating if they need it, and clean and tighten all the connections
He or she should also check the oil motors and the belts to see if they have worn down or lost their tightness
Check how accurate the thermostat is.

Checking, maintaining, and repairing the AC unit might seem like a daunting task or a somewhat unpleasant chore but, as we demonstrated above, it’s crucial. Not only will checking and maintaining it keeps it from breaking down, but it will save you money and energy as well.

The Best 9 Through the Wall Air Conditioner Systems of 2016

May 3, 2016 by itadmin

Through the wall air conditioners are also known as in-wall air conditioners or, simply, wall air conditioners. They are called thusly because they are mounted into a hole in the wall and because they are attached on a permanent basis to your house. They are the perfect solution if for example, you’ve just bought your dream home or if you’re planning on living in the same house for a longer period. However, if you know this is the right solution for you but are not quite sure which particular one to purchase, don’t worry. Here is an excellent list of the best 9 through the wall air conditioner systems of 2016.

Top through the wall air conditioners and their reviews

#9. The LG LT123CNR

Reviews give this one 6.5 out of 10. That is because it lacks some main features and because of its size. Users believe it to be far too big for the power it offers.

It’s well suited for average and small rooms, and it has a remote control and a timer which you can program. Unfortunately, it’s not equipped with a sleep-mode option and, most importantly, it’s not very energy efficient. For example, say your average use over a three-month period is of 8 hours per day. Then you will have to pay some $113.18, which is quite high compared with other units we have on this list.

It’s quite big and heavy, weighing about 80 pounds, but it’s great for removing moisture from the air, should you live in a humid climate. Also, the LG LT123CNR retails at about $1 150.

#8. The LG LT1235CER

This one retails for approximately $600, and it received a 7.93/10 from users and reviewers. It was designed for large rooms and it really does fulfill its purpose, because it manages to cool them off easily and very efficiently. It has a moderate BTU capacity of 11 500. This means that the size of the room it needs to cool can go up to 700 square feet. Also, its 310 cubic feet per minute air-flow capacity means it will cool a room that large quickly enough.

Its energy-efficiency ratio is of 9.8, which puts it at number two on our list from this point of view. The estimated annual energy cost for this through the wall ac unit is $101.09, better than most products. Apart from that, it’s ENERGY STAR qualified.

As far as size goes, it’s quite small, coming in at 14-13/32 inches tall, 20-3/32 inches long and 24 inches wide and weighing 80 pounds. However, you should know that it doesn’t have a sleep-mode or an auto-mode function, which is why it’s placed almost at the bottom of the list.

#7. The Impecca

The Impecca received a 7.98/10 from users and reviewers alike, and it retails for $500. Its primary quality is that it has an impressive BTU power for heating, cooling, and fan speed options. It comes to some staggering 14 000 BTUs for cooling and 10 600 BTUs for heating a 700 square foot room. Also, it can eliminate up to 2.9 pints of moisture per hour.

Its energy efficiency rating goes up to 8.5, but it’s still one of the lowest on this list. Even if it is ENERGY STAR certified, it will still cost you some $142.56 per three months to run it. On the cons side, the Impecca comes with many acccessories and features, one of them being the remote control. It also has a programmable 24-hour timer and an auto-mode feature which allow you to run it as efficiently as possible.

Another great thing about it is that it goes beyond heating and cooling. It also has the option of circulating the air without refrigerating it, should you consider it’s not hot enough to use the ac. Apart from that, this unit allows you to use only its dehumidifying mode, separate from the ac itself.

#6. The GE AJCQ10ACF

It costs approximately $700, and it received an 8.4/10. Its BTU power is quite median, as the unit offers 10 400 BTUs. These are sufficient to cool a 425 square foot room. It has a moisture-removal feature that can remove up to 2.7 pints per hour in said room. One of its main pros is that it works on R-410a refrigerant. It’s known to be a lot friendlier to the environment than some older refrigerants, such as R-22.

As far as cost and energy-effectiveness go, the GE AJCQ10ACF is one of the best on the list. It has two certifications, one from ENERGY STAR and the other from AHAM (The Association of Home Appliance Manufacturers). Its energy-efficiency ratio is a whopping 9.8.

#5. The GE AJCQ12ACF

Another GE model is the AJCQ12ACF. It retails for $711, and it received an 8.4/10 from users and reviewers alike. It was designed for medium rooms of about 550 square feet, so it offers some 12 000 BTUs. It uses the R-410A refrigerant, which is known to be environmentally-friendly. As far as humidity goes, this ac is among the best. It’s actually able to remove some 3.4 pints of moisture from the air. But, it lacks the ability to use the dehumidifier separately from the ac, so you need to run them both at once.

Its estimated annual cost goes up to $105.41 for three months. It received its certification from both ENERGY STAR and AHAM. Also, it’s UL listed. This translates into the fact that it has passed public safety standards. Its energy-efficiency ratio goes up to 9.8.

#4. The Frigidaire FFTA1233Q1

The Frigidaire through the wall unit costs approximately $620, and it received an 8.68/10. It too was designed for medium rooms, which means it brings some 12 000 BTUs to the table that can cool down a 550 square foot room easily enough. In a humid climate, it removes up to 3.3 pints of moisture from the air in the space of an hour.

Its energy-efficiency rate is high – 9.8, it costs a little over $100 to keep it running for three months, and it received its certification from ENERGY STAR. It has an auto-restart function which allows it to turn itself back on after a power shortage. It’s quite small and only weighs 72 pounds. Another great pro for the Frigidaire is that its filter is made of antibacterial mesh and is very easy to clean.

#3. The Friedrich Uni-Fit US12D10B

We have now reached the best three through-the-wall air conditioners of 2016. Third place goes to the Friedrich Uni-Fit US12D10B. It retails for about $690, and it received an 8.68/10.

For its cooling abilities, users and reviewers awarded it 8.1/10. It packs some 11 500 cooling BTUs, enough to cool down a 550 square foot room. This means it’s perfect for people living in apartments. Its humidity removal feature is quite impressive as well, the unit being able to remove 3.8 pints per hour. But, again, just like with other units, you can only run the dehumidifier along with the cooling mode.

For efficiency, it received a whopping 10/10 and for ease of use – 6.3/10. It also has a great design which users loved because it has six-way directional air louvers while most units have only four.

#2. The Keystone KSTAT12-1B

It retails at $635, and it was awarded an 8.73/10. It’s worthy of the silver medal mostly because of its energy saving features. Its energy-efficiency ratio climbs to a satisfying 9.8, as it will cost you approximately $105 to run it 8 hours a day for three months. The unit is ENERGY STAR approved, and it made it onto UL’s list as a public-safe appliance.

It also has quite a few features that will prove highly convenient for the every-day user. It has a remote control which will give you more freedom in operating it and an auto-restart function in case there’s a power-outage, and you forget to turn it back on or you are not at home when it happens. Apart from that, it also has and energy-saver mode, a sleep mode, and a programmable timer.

#1. The Kenmore 70151

The Kenmore 70151 takes home the gold medal for being the best through the wall air conditioner with heat of 2016. It costs $500, and users say you will love it. It’s very effective when installed in large rooms of up to 900 square feet, seeing as it has 15 000 cooling BTUs. Its maximum air flow of 362 cubic feet per minute makes it the most powerful unit on the list. However, take into consideration that, if you have a small room that needs ac, you might be better off with a slightly less powerful unit. The Kenmore might freeze up the space.

It has energy-efficiency ratio of 10.7, the highest on the list as well. The average cost of running this beautiful appliance for three months 8 hours a day is just $121. It has a remote control that manages all its features, a programmable timer, and a very sensitive sleep-mode. Another great thing about it is that it has a fan-only option. This means you can create a breeze without turning on the compressor. You will truly appreciate this feature at nighttime, in the spring, and autumn.

Installing a through the wall air conditioner

After you have decided which of the above 9 through the wall air conditioner systems is best for you, you need to install it. You have two options – calling in a specialist or doing it yourself. In case you have picked the latter, here are the quick steps you need to follow.

Select the location of the ac
Locate the wall studs by lightly rapping on the wall and lightly mark them in pencil
Clear the selected area of molding, drywall, and insulation
Relocate the ac’s dimensions or sleeve into the inside of the outside wall
Create the hole that will fit the actual unit
Build the necessary support
Fabricate the header which will be top of the opening framework
Add the studs
Finish the unit’s frame
Install all the electrical outlets you believe the ac will need while the wall is still open
Carefully reconstruct the wall
Install the actual ac unit
Caulk around it very carefully, as this is the layer that will keep water out
Install the molding and secure it with finish nails

Here are the top 9 through the wall air conditioner systems of 2016. Before deciding which one to purchase, make sure you carefully read all the details regarding it. As shown above, the shopping choice very much depends on the requirements of the room you’re planning on putting it in. Even so, you can’t really go wrong if you thoroughly read our guide!

Here’s What You Need to Know about the Honeywell Lyric Thermostat

March 22, 2016 by itadmin

Those days when you used to argue with the rest of your family about the temperature in the house are over and done with. You don’t even have to get up off the couch or be at home anymore, because Honeywell have introduced their brand new super ‘smart’ line of thermostats, specifically designed for you to control via your smartphone. The Lyric thermostat is so smart that it will actually sense when you come home or when you leave and it will set the temperature in every room according to that. It’s a revolutionary product and here are all the details you need to know about it.

The Honeywell Lyric’s Design

The Lyric thermostat is a round device, with a white interface and chrome trimmings. It has a rather small round touch pad in the center that normally displays the temperature. On top of this brand new smart thermostat you will find a screen shaped like an arc, which is there to tell you if the Lyric is cooling or heating up. You also have a weather icon to the left which, upon touch, will tell you the local weather. On the right you have the ‘Away’ button, which will allow you to set your preferences for when you are not at home.

The way in which you can operate the device, meaning turning the temperature up or down is by gently turning its outer ring. As far as the design goes, the Lyric thermostat also comes equipped with a white plastic shield that you can use or not, if you wish to cover up any holes in the wall.

Installing Honeywell’s Lyric Thermostat

Fortunately for all home users out there, installing this super smart thermostat is actually very easy, thanks to the people over at Honeywell. First of all, you need to download the Lyric app on your smartphone, because you will receive all the instructions there.

Then you need to shut down the system’s power. After you’re done with that, mount the thermostat’s baseplate on to your desired wall, cable in all the required wires and then strap on the top half to the baseplate. This piece will complete the set up and hide all the wiring.

You can then connect to the Lyric thermostat through your phone, as long as you have Wi-Fi. While connected, you need to configure the device to the hot and cold temperatures your desire, tell it the type of system you have and let it know your location. Reviews report that, on average, installing a Honeywell Lyric thermostat takes somewhere between 20 to 25 minutes and it doesn’t require a pro to come in and do it for you. You can do it yourself. Make sure it’s well wired before you turn it on.

In order for the Lyric thermostat to work, it will need one lithium AAA battery, which you will need to change every year. Something that you need to know about the installation process is that, after you have put the battery in, you have to let the heating mode run for 5 minutes, then the cooling mode for another 5 minutes, so that the smart thermostat can determine what are your HVAC system’s power requirements.

The Lyric’s App

Reviews show that the app as well, just like the thermostat in itself, is very easy to use and will become your best friend when it comes to acclimatizing your house. When you open it, a small circle placed at the top of your screen will show you the exact temperature in your house, even if you are away from home. The background will be either blue, for when the thermostat is in cooling mode or amber for when it’s in heating mode.

Below this, your entire interface will show your event settings, which you can configure according to your preferences, like “I’m leaving”, during the day or “I’m going to sleep”, during the evening. You can even set the Lyric thermostat to go into Eco mode, for night time and you will find that this particular feature will save you a lot of money when it comes to your heat and electricity bills.

The app itself allows you to virtually control the device from anywhere you are, as long as you have a smartphone, a tablet, or an Apple watch. It has the Geofencing function that uses your location to control all your settings in an automatic way. For example, if you set it up correctly, the programmable Lyric via the Geofencing function will know to start heating up your home right before you come home so that you don’t walk into a freezing house.

Another great app that comes with the Lyric thermostat is the Fine Tune one, which will make slight changes in the inside temperature according to outside weather conditions. So, you really don’t have to worry about anything, just sit back and let the Lyric take care of everything.

It also has a Smart Cues alert which will notify you when your Lyric requires attention, like replacing one of its filters, its battery, or some service. You can use whatever Apple device you own and link it to the thermostat, even your Apple watch, and you can use Siri as well in order to give it commands. However, Siri requires you to install the Apple HomeKit first.

Apple’s HomeKit works like an intranet, which takes control of all your home products via its apps and enables them to interconnect. Privacy is a given with this Apple add-on, so you needn’t worry, because all your personal data is encrypted at all times. This means that when you program your lights to turn off or your thermostat to turn on, for example, the only people who will be aware of these changes and of your settings are the ones who are actually inside the house at that given moment.

As far as the app and programming goes, it will also send you signals or notifications when a person enters or leaves your house, but some users reported that it actually took a few weeks before this feature kicked-in properly and started notifying them about human transit through their house.

On the cons list, users also added one problem that Honeywell seems to be aware of and working on as we speak. The thermostat is not compatible, unfortunately, with every kind of wireless router. So, make sure that you check what kind of router you have before purchasing and installing the Lyric, at least until the mother company takes care of this issue.

Users have also found the Lyric to be a major update in the thermostat world from Honeywell’s older digital models, such as the DT90E, the DT92E, the Honeywell Electric TL8230a1003, the TH8110u1003, FocusPRO® 5000 Honeywell digital thermostat or the VisionPRO 8000. Therefore, when it comes to replacement, the Lyric is the way to go.

Key Elements to Be Aware of Before Installing

Here are some technical facts you need to know about the digital Lyric thermostat, so that you can make sure it’s completely compatible with your house.

As far as third party products go, the Lyric works with Apple devices, Samsung SmartThings, and the Apple HomeKit. Apart from that, even if you do have Apple products, you need to set them properly in order for them to work with the Lyric. You can find the instructions on Honeywell’s website.
The Lyric app works with Android as well, versions 4.2 and above, which means starting with Jelly Bean, but Apple is preferable. It’s not supported, however, by Blackberry or the Microsoft technology.

There are a number of third party apps that can hook into the Lyric and which you can use in order to make it work even better, but you need to check their website to see exactly what those apps are, what they do and how you can install them.
The Lyric Honeywell thermostat can also control your dehumidifier. If you don’t have one, it’s capable of dehumidifying your home via your air conditioner.
In order for all the Lyric’s apps to work you need to have Wi-Fi in your home at all times. If you don’t, the apps won’t work, but you can still use it as a basic thermostat and make the changes manually. Be aware that, in this case, the thermostat will be non-programmable remotely.
The Lyric comes equipped, right out of the box, with a wallplate, a trim ring which is optional, two screws that you will need for mounting, its wall anchors, and a Quick Start Guide that is basically a manual and which will show you how to install and use the thermostat.
If you have troubleshooting problems, you can visit Honeywell’s website, where you will find all the help you need.

The Honeywell Lyric thermostat retails for $279 and it’s one of the best smart thermostats out there. It offers a variety of apps that will truly make your life easier and definitely more comfortable.
