Air Conditioner Season Is On

The heat is on. Time to turn on the air conditioners to prevent tempers from seething, and to avoid being roasted in the scorching summer heat, or worse, suffer a heatstroke especially during the day. These appliances are a necessity especially in places, such as Brisbane, Australia, Charlotte, North Carolina (NC); Las Vegas, Nevada; Los Angeles and Sacramento, California; Tampa, Jacksonville, Miami, Yulee, and Orlando, Florida (FL); Tucson, Arizona; Oklahoma; or Dallas and Houston, Texas, where summer really sizzles. Air conditioning is indispensable in other hot countries like Pakistan and the Philippines. The blistering climate in India has also led a number of companies there to come up with their own brands of air conditioning (I have also heard referres to as: air con in some parts of the world), such as Godrej, Voltas, Videocon, o General and ONIDA, which you can switch on even while you are not home yet using SMS.

Places with milder summers, such as Nashville, Tennessee, Denver, Colorado, Louisville, KY, San Jose and San Diego, California, Indianapolis, Indiana, Philadelphia, Chicago, Atlanta City, Georgia, may be comfortable in their non-airconditioned home.  Nevertheless, they still need an HVAC system to help them weather the swings of the season especially during the cold months of winter.

We usually take air conditioning for granted especially when everything is functioning well. We owe air conditioning to Willis Carrier from Syracuse, New York, who invented the first electrical air conditioning. The initial use of this first system was more for industries, such as in a printing plant and later on in other workplaces. It was only later that air conditioning was also used for residential comfort as well as in automobiles.

Like exploring a gallery of air conditioners in an appliance center or in an HVAC specialist office, let us take a look at some of the types and brands that are indispensable during the warmest season of the year.  We will also look at some of the factors to consider to help you compare and buy the right model.

Other Factors To Consider Besides Central Air Conditioner Prices and Brand

With countless brands inundating the market, you may already be pulling your hair while trying to decide which air conditioning system to buy. Besides making a choice between one brand vs another, you also have to choose what type of system you would be installing, from window-fitted, floor-mounted, split type, or the one with variable refrigerant flow system. Brands with VRF systems include Toshiba, Fujitsu, Daikin, Mitsubishi, Hitachi, Sanyo and Panasonic.

Your contractor may also have various ways of installation. For instance, a contractor in Toronto, Ontario is offering the Attic Pak systems, which are low velocity AC systems ideal for homes without duct work or for homes with forced air and with more than two stories. A condensing unit is installed outside the home, then the lines from the unit is extended up to the attic where an air handler is positioned. The latter controls the flow of cold air into the house via 5, 6 or 7-inch outlets. This type of system is known to consume less energy and be more quiet.

To help with (or further complicate) your buying decision process, here are some more central air conditioning brands and models to add to your list:

Airwell-Fedders

Amana

Bryant

Comfortmaker

Ducane

Emerson

Gibson

Heil

Honeywell

Intertherm

Luxaire

Miller

Nordyne

Payne

RUUD

Tappan

Tempstar

Weather King

Janitrol

The last, Janitrol, has been receiving a pile of negative rating and reports online. Examples of specific central air conditioning models that are more energy efficient are the Lennox XC16, Lennox XC21 (the most efficient and quietest central air conditioner you can buy), LG Ductless Multi-Zone air conditioning system, Carrier Infinity Series, and the American Standard Gold XI (also known as the Allegiance® 15). Research them online so that you can make an intelligent comparison review.

When deciding on which central air conditioning system to buy, consumers often stew over features, pricing and brands. Naturally, you would want to get your money’s worth so you check performance vis-a-vis price. But there is another key factor that often fails to get much consideration – the Heating, Ventilation and Air Conditioning contractor to hire. No matter how expensive the air conditioning system you buy, or what brand you have installed, if the contractor you hire lacks the expertise, you can still possibly end up losing your cool over your purchase. For instance, a competent contractor must be able to give you an intelligent answer if you ask him if installing a 220 Volt air conditioner costs less or helps you to decrease electric consumption as compared to using a 100-volt type.

So make sure that when you read each of their profile, you also know how to screen a reputable contractor. Consider the advice of the Air Conditioning Contractors of America (ACCA) in their website on how to choose a contractor including tips on what to ask prospective contractors and a checklist of what contractors ought to do in servicing their customers, since not all of them perform all the necessary tasks. The site also includes a scoring system that allows you to rate each prospect. Another organization that can help you with choosing a contractor to install your central air conditioning system is the American Council for an Energy-Efficient Economy.

Besides being installers, most likely these contractors are also dealers of spare or replacement parts and supplies, such as scroll compressors, capacitors, registers or vents with a damper, refrigerant hose, decorative ducts, the thermostat, wiring, fan motor oil, and other accessories that you may need, such as air conditioner covers (e.g. quilted cover, lattice cover, an exterior air conditioner cover, or Poly air condition cover), filters (e.g. disposable pleated air filter, washable and reusable air filter, metal air filter, HEPA filter, or a scented air filter), wall sleeves (e.g. Haier Through-The-Wall Sleeve or HTTWS), and support brackets. They also typically carry other air quality control devices, such as dehumidifiers. So when replacing any of these parts, you may need to contact your contractor.

One brand filters that you may consider is the 3M Filtrete. It boasts of electrostatic technology that attracts, thus, helps to get rid of the contaminants and hazardous particles from the air that is circulated indoors. This means comfort for a person who suffers asthma or an allergy. These air filters come in various sizes; pick one based on the type and size of the air conditioning system or furnace.

You will also be needing the services of your expert contractor for cleaning, periodic maintenance and repairs especially if you do not know how to troubleshoot the problem. Nonetheless, you may also want to learn DIY troubleshooting techniques when your AC is not running properly. Make the manuals your guide in obtaining a basic understanding of how the system works by studying them, including any instruction for troubleshooting and the diagram of the system. Common problems that you may encounter include: water leaking from the air conditioner into the room; central AC not cooling even if the condenser outside the house is working; the unit is blowing a bad smell or is blowing hot instead of cold air; and when your air conditioner is freezing. Let your contractor fix problems that you cannot handle.

Depending on your knack for thermodynamics and fixing appliances, there are certain air conditioning problems that you can do yourself. For example, your air conditioners may stop working or loss its cooling capacity. If you read the manual, you may learn that one possible cause for this is when the starting capacitor, located on the outside compressor or condenser unit, is defective. One of the troubleshooting techniques that technicians employ when an electrical motor does not start, whether an air conditioning compressor motor, a refrigerator pump, blower motor, or freezer motor, is to simply install a simple and cheap starting capacitor to give the appliance an extra voltage jolt to get the hard-starting motor to run.

There are a good deal of contractors available to install, replace, service, clean ducts, balance air and maintain your AC system. Here is a list of some of these contractors and their respective place of operation:

A-11 Air conditioning in Fort Worth, Texas

Blue Air in Austin, Texas

EZ Air Conditioning and Heating in San Antonio, Texas

Polar Air Conditioner Repair Corp. in Hollywood, Florida

Holiday Air Conditioning in Fort Myers, Florida

Del-Air for homeowners in Macclenny, Florida

Jim’s Air Conditioning in Crestville, FL

Bel-Red Heating and Conditioning in Washington

Polar Bear Air Conditioning and Heating in Washington DC

Level Heating in Baltimore

Magic Touch Mechanical Inc. in Mesa, Arizona

Yellow Dot in Raleigh and Durham, North Carolina

Air Wave Air Conditioning Company in New York City (NYC)

Willis One Hour Heating and Air Conditioning in Kentucky and Ohio

Sears Heating and Cooling Sales, Service and Repair in Hillyard, Washington

Scottsdale Air Heating and Cooling in Scottsdale, Phoenix, Tempe, Paradise Valley and the entire West Valley

Custom Air Conditioning in Canada

Frost Air in Sydney, Australia

Choose one which is nearest you. It would also be in your best interest to make sure that the contractor offers a warranty for their installation job so that at times when you encounter problems, such as a leak from your unit, they can service it free of charge while it is still covered by the warranty.

Choosing A Window Air Conditioner

The favorite type of air conditioning unit to cool small areas or single rooms is the window air conditioner. Some brands of room and window air conditioners you can choose from are: Hampton Bay, Maytag, Frigidaire, MIRA-Cool, Sunbeam, Sunpentown, Goldstar, GE, QuietMaster, Samsung, Whirlpool and the market leader in wall-mounted ACs – Bard.

Some specific models of these appliances are the:

Carrier 51PH models

Kenmore 76081 and 73069

Zenith 6500 with remote control

Haier AC, Zoneaire DMA models

the Sharp Plasmacluster AP7GSY

Frigidaire FAA055P7a and FAA065P7a

Frigidaire’s FRA084KT7 8,000 BTU Slider/Casement Air Conditioner

Friedrich WS16B30 27in Thru the Wall AC

Friedrich Wallmaster WS14B10, WS08B10A, WS10B10A, WS13B30B, WS16B30A, 5200 BTU

If you are looking for a cheap brand, consider the Frigidaire FRA52XT 75,000 BTU Mini Window Air Conditioner. If you prefer an energy efficient and environmentally-friendly unit, consider the Haier ESAD4066 Paragon Eco-Conditioner 6,000-BTU Energy-Star Window Air Conditioner or the solar hybrid model of LG that you can power by charging it through its solar panel. Another solar-powered air conditioner is the SplitCool DC18 DC air conditioner, which efficiently converts DC power from solar panels into AC power to operate a standard air conditioner without the need for an inverter to convert solar DC current into AC current. It can come as 12-, 24-, and 48-volt powered units. Do not forget to recharge its 12 VDC battery to make sure that you have enough power especially if you plan to turn your air con on at night. Battery requirements and recharging time will vary depending on local sunlight conditions and the specific use of the air conditioner.

To go the extra mile in protecting the environment while cooling your home, you may also opt for units that use Puron refrigerant, a refrigerant engineered so as not to damage the ozone layer. It is an approved substitute for Freon 22.

When installing a window air conditioner, do not forget to buy the brackets to support it. For window units that are between 12000 and 24000 BTU, the 160-lb Air conditioner brackets can ably support them.

You bet, there are many different brands & models of air conditioners, so it can make the buying decision process very difficult. You have to do a lot of research to compare and choose from the various models that appeal to you. You can also visit local HVAC specialists and other shops that sell air conditioners, such as Home Depot. Another way to test drive the particular model that you are eyeing is to rent it from a rental shop so that you can get a feel of its features and performance especially if your stay in your current place is not yet permanent. You can also find many air conditioning rentals online.

Another important detail to consider when installing an air conditioning system (whether for ACs that you mount on windows, AC for windowless rooms, for vertical sliding windows, the horizontal type, split type, central air, or whatever type) is the size and cooling capacity of the unit, which is a function of the space you are planning to allot for. The space that could be handled by a certain air conditioner or its cooling capacity is measured in British Thermal Units (BTU) per hour. For an area that ranges from 100 to 150 square feet, the BTU of the air conditioner should be 5000 BTUs. For 150 to 250 square feet it should be 6000 BTUs, 7000 BTUs for 250 to 300 square feet, 8000 BTUs for 300 to 350, 9000 BTUs for 350 to 400 square feet, 10000 BTUs for 400 to 450, 14000 BTUs for 550 to 700 (your 4-ton AC), 18000 BTUs for 700 to 1,000 square feet and 24000 BTUs for 1000 to 1400 square feet. Sizing air conditioners according to the space needing cooling is made easier with the use of an air conditioner calculator.

Portable Air Conditioners for Specific Spots

Besides room or window air conditioners, here are some other uses for portable air conditioners, which can be used to condition the air in specific spaces such as rooms with specific sizes and particular spots that need additional and continuous cooling, such as in bigger rooms in larger residential homes, to cool computer systems that cry for more cooling in offices or in a data center or the local library and in any commercial environment, to ventilate a grow room, or to cool certain machinery in an industrial setting. The ventless type can condition the room without needing to vent out to an outdoor unit. One type of portable air conditioners is the desktop air conditioner which you can simply mount on your office desk should you need extra cooling. Humidifiers may also be used to get rid of excess humidity, but it cannot completely dry the air. Portable air conditioners are compact making it easy when moving it from one area to another allowing it to be used in any part of your home or building. They can be narrow and can stand in vertical position to save space. A portable air conditioner may also be used during an emergency or in an automobile, or even in a boat, and can be very handy for an RV camper.

Soleus PH3-12R Air is claiming to be the number 1 portable air conditioner supplier in the US. Other models of these compact coolers are the:

Amana AP095R

Sharp CVP12LX

Haier HPRB07xc7

Delonghi Pinguino

Soleus PH4-12R-01

Edgestar Server Cool

Friedrich ZoneAir P12A

Whynter 12000 and 14000 BTU

Royal Sovereign ARP 1000ex and ARP 4012h 12000 BTUs

Sunpentown WA1061H SlimLine which comes with a heater (10000 BTU).

Amcor NanoMax A12000E, AF9000E, ALTL12000E, ALT12000E, PLM14000e, PLM16000e and KF9000e

Other brands include Danby, Everstar, Kooleraire, Windchaser, and Midea.

When using a portable air conditioner, make sure to have the exhaust hose that leads out of the house insulated so that outside air does not get back into the interior of the room.

The Personal Portable Air Conditioner

One unique portable air conditioner is the Coolware Personal Outdoor Cooling System which is worn around the neck. It is also known as a neck cooler mini air conditioner. It’s constructed of Anodized aluminum and may be one of the smallest air conditioners. Another personal air conditioner is called ICEflow, which employs the environmentally-friendly Peltier Effect to allow you to feel a 74 degree breeze every time the room temperature rises up to 80 degrees, without the need to add ice. A free-standing compartment, where water freezes into a block of real ice after charging overnight, is inside this gizmo. When the fan is turned on, the cooling breeze flows across an ice-cold chilling plate.

Thank Goodness For Goodman Air Conditioners

Goodman is one of the long-standing brands in the air conditioners and heaters business. It got many good reviews from its users but many consumers also rated it negatively. Now, let us focus this discussion on a specific Goodman model – the Goodman GSX13 Series 13 SEER R-410A 3.0 Ton 36,000 BTU

This model boasts of high performance of up to 8.4 HSPF/13 SEER energy heating performance and even durability for heavy duty use. It uses the chlorine-free R-104A refrigerant, a high-efficiency condenser coil constructed from corrugated aluminum fins and rifled refrigeration-grade copper tubing, a factory-installed bi-flow, liquid line filter dryer, and a louvered cabinet constructed from heavy-gauge galvanized steel that safeguards the coil. The casing has an appliance quality finish that can withstand the effects of time and any weather condition.

The Trouble With Air Conditioning Troubleshooting

Every homeowner, with a home equipped with a residential air conditioning system, must acknowledge two types of air conditioning problems: (1) those that you can troubleshoot on their own; (2) and those better left in the hands of a qualified technician. The problem with air conditioning troubleshooting is if the troubleshooter does not have sufficient knowledge of how an air conditioning works and just leave everything to guesswork. That is why, before you start playing the resourceful MacGyver, make sure you have some basic knowledge of air conditioners.

Before You Start Troubleshooting Central Air Conditioning – Dissecting Your A/C

How an air conditioner works, whether for the home, car and other places, can be condensed in one sentence: The refrigerant circulates through the compressor, evaporator, and condenser to make the air cool.

This is the longer but still simplified version of how it works: When you turn on your central air conditioning system, its thermostat intelligently gives the air conditioning system a cue to bring own air temperature, leading to an entire chain of events. The part which handles the air is set on, sucking in air from different parts of the house via return-air ducts. The system then draws this air through a filter where lint, dust and other particles in the air are removed. Some innovative filters can even extricate microscopic pollutants. The air is then is dispatched to the air-supply duct work, where it is circulated back to the different parts of the house. This cycle repeatedly takes place while the air conditioning system is in use.

Now, let us take the system to pieces and take a look at the respective roles of each part.

Compressor. This motor is usually situated outside the house. Living up to its name, it compresses low pressure refrigerant gas into a high temperature, high pressure gas and hauls the refrigerant between the evaporator and condenser.

Evaporator or Cooling Coil. The cooling coil is located inside the air handler and is part of a finned tubing where liquid refrigerant is gauged and allowed to evaporate transforming from liquid to gas state. This transformation leads to heat absorption making the surface of the evaporator coil cool. As a result, it blows cool indoor air across the coiling coil.

Condenser. This air conditioning component located outside the house includes a condensing coil through which high-pressure refrigerant gas circulate. It is also where a blower blows air to cool the refrigerant gas to convert it back to its liquid form. This happens to release the heat from the refrigerant gas, including the heat collected from the house, to the air fanned by the blower.

Metering Device. This small tube sandwiched between the evaporator and condenser, measures how much refrigerant is conveyed from the condenser to the evaporator.

Evaporator Fan. This air handler blows air through the evaporator coil to condition it and circulates it across various parts of the house via the supply ducts.

Duct System. This system circulates conditioned air from the air handler into the supply ducts where air is taken and is brought back to the cooling system air handler.

Controls Unit. This unit is comprised of the various controls and features to operate the air conditioning system, such as electrical switches, the room thermostat, circuit breakers or fuses, air filters , and condensate handling system.

A Lennox Air Conditioning Troubleshooting Case in Point

Understanding the various parts of the air conditioning system is important. A malfunctioning part will render the system useless or at least inefficient. Sometimes, despite the troubleshooting measures you take, it may still continue to malfunction if the measures you take do not address the right part that is problematic. You can also just ask the help of an HVAC specialist to resolve the problem. Consider this Lennox air conditioning system owner and DIY enthusiast who successfully resolved his air conditioning problems by finding out which particular component is acting up.

The fan of the outside unit of his Lennox 10ACB24-11P stops running after five minutes or so of switching the unit on and setting the thermostat to cool. The compressor, meanwhile, continues to function. So to troubleshoot this setback, he replaced the fan motor and cap, tidied up the contactors and, tested the old motor with the new cap, unhooked the compressor from power, and tested separate caps for the compressor and fan. Despite all these steps, the fan still discontinued running. After consulting with other DIY enthusiasts, and referring his case to a service technician, he discovered that it was the replacement motor that was the problem. It was a bad replacement that is why the fan still did not run despite the new motor. When replacing busted parts, make sure that it is in good running condition and the right replacement. In replacing a motor, make sure that you got the right size and has the same RPM as that of the original, not just the horse power. Using the wrong type of motor as replacement could overheat and cease operating because it could not take the added strain.

Carrier Air Conditioning Troubleshooting – What To Do With A Unit That Runs But Does Not Cool?

This is a common air conditioning problem not just among the Carrier systems. There are several possible causes for this snag, some of which may just be DIY stuff. So before calling an HVAC specialist, consider some of these troubleshooting pointers.

One of the things you can do to possibly solve this hitch is to inspect the filter located on the return air duct towards the right side near the air handler or furnace in the house. Replace it if it is damaged. Check also for debris that can obstruct the air flow on the coils on the exterior of your unit. Clean it out to allow airflow and heat exchange. Otherwise, your Carrier A/C will just keep on running without cooling your home or room, but the coil will, in due course, freeze up.

If the filter issue is not the problem, you can also check the breaker panel. Turn the breaker off for your AC unit, or of you can find a disconnect box outside near the unit, disconnect the plug inside. To recognize it, see if there is a ring on it with the “On” and “Off” label. Then clear the unit of any large debris. Afterwards, remove the water hose and clean the coils with a bristled brush and a pressure nozzle. Then allow the air conditioner to empty out and dry up for about 30 minutes prior to turning it on again. Do not forget to plug in the cord that you have unplugged earlier. After which, turn it on to test to see if it functions better. If it just runs but still does not cool, its freon level may be low or may be leaking. In this case, you will have to ask for the help of a HVAC specialist.

Air Conditioning Troubleshooting Chart

An air conditioning troubleshooting chart will serve as a useful quick guide for homeowners to follow procedural checks to be able to troubleshoot their units. It tabulates the various air conditioning problems that may possibly crop up, along with their respective possible causes and remedy neatly organized into columns for easy reference. A few of these charts can be printed.

Troubleshooting Air Conditioner Problems

Now that summer is here, many people would also be saying “Hello” to their air conditioners that are installed at home, at the workplace or in vehicles. Well, you should have said your greetings to this cool gadget, whether auto, home, window, central, or portable, days or weeks before the temperature started its climb to check for and nip possible air conditioner problems in the bud and ensure your comfort even before the weather begins to sizzle. If you have not done so yet and you have encountered some glitches, don’t sweat it. Continue reading to find useful troubleshooting tips.

No Sweat Common Air Conditioner Problems

Almost all air conditioner problems can leave your temper seething, and your first reaction may be to pick up the phone and call a technician. You must realize that there are simple problems that you can easily handle yourself to help you save the money.

So here are some common air conditioner problems that you can handle, no sweat!

Wailing noise. This can really be irritating so better resolve it before it gets louder causing you to lose your cool. Check for a dislodged fan belt and put it back its proper place. Also find out if the bearings of the motor need to be lubricated or replaced.

Leaking water inside the house. This may be due to your unit failing to drain away condensation, probably because of a rusty condensation pan. Start your inspection here then down to the drain itself to check and clear clogs so that water can trickle down where it should trickle down.

Blocked grills. This can cause your unit not to work. To address this, disassemble the unit so that you can carefully wipe down the parts, such as the fan, fins and motor, to enable it to function more efficiently. Make sure that it is disconnected from power and that the moving electrical parts remain dry. Be cautious in taking off the top grill because it may be wired to the fan. After cleaning, put everything back together and test it. Check thermostat settings to make sure they are below the current ambient temperature.

Solutions To Home Air Conditioner Problems Related To Energy Consumption

We can go on and babble about leaking units, busted fuses, malfunctioning condensers, but the there is one problem that does not receive much attention – the substantial energy consumption of A/C’s. Air conditioners are among the top home appliances that are significant contributors to the high energy bill you are paying. So to help you mitigate this problem, consider these tips:

1. Dirty filters can increase your energy consumption because they cause the conditioning systems to work harder to be able to pull out air through the unclean filters. Save five percent of your energy spending by cleaning a dirty filter. This will also minimize CO2 production by 175 pounds.

2. Over-cooling the room can also rob you of your energy savings. Set your thermostat at 75 degrees in the summer. This is deemed the optimal temperature level just enough to enjoy the cool that you need to combat the scorching summer heat and at the same time curtail your energy bill.

3. Positioning the unit in a spot where it gets exposed to direct sunlight can also pose energy bill problems. Reports have shown that energy consumption is five percent less with air conditioners that are stationed in shaded places when compared to those getting direct exposure.

4. Insufficient insulation of ducts for central air conditioning units can also increase energy consumption. So to lower your electricity bill, see to it that the ducts are properly insulated.

Window Air Conditioner Problems? Don’t Sweat The Small Stuff

A window air conditioner, also known as a room air conditioner, is the “Mini Me” of a complete house cooling system. It contains the same components as that of an entire cooling system but in smaller sizes. These include interior components, such as the blower, evaporator coil, thermostat, plastic face panel, and filter; and other parts that are positioned outside the window, such as the condenser and compressor. Extending from the interior component evaporator coil to the exterior condensate drain tube is the moisture condensate. It serves to empty out water. All these are tidily enclosed in a metal casing which is partially positioned in and out of a window of a room.

As with an entire home air conditioning system, you may also encounter window air conditioner problems. However, do not let this get you into such a sweat as some of these can be resolved yourself.

Consider these tips:

1. If you see your unit leaking with water from the front panel, it may be because the pan is inclined down toward the room, instead of towards outside. As a result, water coming from the evaporator coil trickles down through the drain tube into your room, rather than outwards onto the rear or the unit. To solve this snag, simply adjust the slope of the unit to the appropriate position to allow water condensate to drain outside.

2. If your window air conditioner does not come to life after you have switched it on, check your power plug connection. It may just be loosely plugged and can easily be solved by using properly-positioned power plug connection. It is also possible that the circuit breaker or fuse has blown, so what you can do is to reset the breaker, or replace the defective fuse.

3. If your unit fluctuates to on and off too often, the problem may be with the thermostat or the temperature sensor. To troubleshoot this hiccup, adjust the wire with care to ensure that the thermostat sensor is correctly sitting close by the evaporator coil. Also find out if the thermostat or a portion of the front panel is not blocked with drapes. If the problem amplifies, have it checked by a technician for possible refrigerant leak. Also make sure that the condenser is not clogged with leaves and that its fins are not seriously mutilated or contorted. Fix twisted fins using a fin comb.

5 Hot Tips To Prevent or Curtail Central Air Conditioner Problems

1. Replace the filter. Clean filters not only nip problems in the bud and ensure a properly functioning central air conditioning system, but also allow you to save on your energy spending. A few AC makers even advise replacement every month or every two months, hinging on the frequency of use.

2. Allow the condenser some rest. Just as you take the time to unwind in the summer, your air conditioner also needs some time off. Overusing it will not just push your energy bill up, it could also lead to malfunction. Turn it off when the weather is cool, such as during the early morning hours, and when nobody is at home. Set the thermostat at 65 degrees or higher if you are using it.

3. Clean the vents. Periodically check the vents for any obstruction. Wipe away dust and dirt to allow air to sufficiently and efficiently flow.

4. Clear the outdoor unit. The HVAC motor is housed in the large box that is sitting outside your house. Make sure that its surroundings are free from clutter to allow about one to two feet of free space surrounding the vents. Never put anything atop the unit, especially when it is running. It would be a good idea to cover it during the summer when it is not in use to shield it from moisture that can lead to rusting and corrosion.

5. If you sense that something is wrong, turn it off. Try some of the troubleshooting techniques you may know, but if those do not work, do not push the system to struggle on to avoid further damage. Instead, just shut it off and have it checked and resolved by a qualified technician.

Air Conditioner Compressor Problems Can Compress Your Wallet

When you sense some problem with your air conditioning unit, pray that it does not concern your compressor since repairing (or worse, replacing) it can cost you an arm and a leg. One of the most common compressor problems is losing its capacity to cool. A service technician can diagnose this by connecting certain test gauges to the system. If he detects discharge pressure that is lower than normal and suction vacuum higher than normal, this will confirm the issue. A competent technician though will not do this test right away to minimize cost and to be methodical, except if he sees palpable signs that there is something wrong with the compressor, such as hard starting, does not start at all, and noise). He would follow certain standard procedures in examining the system, beginning from the least-expensive, like checking for electrical power, right setting and operation of system controls, function of blowers, condition of filters and duct work, and the like, to the problems that would cost more, such as those concerning the compressor. He examines the compressor by checking the pressures, air conditioner operating temperatures and current draw in Amps.

Car Air Conditioner Problems That Make Your Ride Uncool

Just like your home air conditioner, the air conditioning system in your automobile may also go kaput, making your ride sticky and uncomfortable especially when driving in the summer heat. Brace yourself from this vexation by getting familiar with some these common car air conditioner problems.

Low or Zero Level of of Refrigerant or Lubricant. A large number of car air conditioner problems are a result of the insufficient or zero levels of refrigerant. Certain auto air conditioning systems even disable the compressor from turning on if refrigerant levels are low, hence, cannot flick the low pressure safety switch. The refrigerant, and its oil components, is not just responsible for giving out the cooling effect, it also ensures the proper lubrication of the seals and certain moving parts of the compressor. This is the reason why the system must regularly be turned on, even during the cold months. To keep the compressor from drying up, make sure that the mineral oil is topped up when the system is undergoing maintenance.

Fluctuations in Air Temperature. There can be many causes for an air conditioning system that blows cool, and then hot air, such as a defective AC on/off switch, a lousy temperature sensor, a malfunctioning clutch or clutch relay, a broken low-pressure cutout switch, a blown fuse or faulty wiring, or an inoperative controller module. Another reason would be a frozen tube or evaporator, hence clogging the circulation of the refrigerant. This usually results from the presence of air or moisture in the system. You can diagnose this with the use of an air-con vacuum pump to see to it that the system has no more than two percent air by weight. This certain level is required for optimal function. Some owners of the Dodge Durango have experienced this hot and cold air problem.

Dripping Air-Conditioner. Another prevalent problem with the AC system of vehicles is leak, which is caused by the declining level of pressure shortly after charging the system with refrigerant. Wet marks around seals and service ports are the symptoms to watch out for. If you drive vehicles with R-12 systems that contain more oil in the system, you can easily detect this. But it may be challenging to diagnose this problem using this technique if you have the later systems, particularly the R-134a, and may require a special equipment, such as an electronic freon sniffer and UV light to pinpoint leaks. Certain vehicles like the Jeep Grand Cherokee have this issue.

Honda Car Owners Steaming Over Honda Air Conditioner Problems

The various car models of Honda is not exempt from car air conditioner problems. For instance, a common complaint for Honda Accord owners is that their air conditioning system just stopped working. This could be due to a missing clutch relay or some burnt wires or a hole in the tube. Some Honda Odyssey owners also complain that their air conditioning fans, which work only at high setting, blow hot air only. This can be resolved by checking the control panel; the transistor panel may just need to be replaced. You can also refer to the above-mentioned tip on temperature fluctuations. Honda CRV is this manufacturer’s car model receiving one of the highest complaints about its air conditioning system. This is briefly discussed below.

The Blackest Snag Among Honda CRV Air Conditioner Problems

The air conditioning systems of some Honda CRVs die a slow, black death. The epithet refers to the black sludge and metal fillings that contaminate the system leading to the breakdown of the compressor. This black debris is pumped through the system as the compressor goes on the fritz, entailing substantial and more expensive repairs, which would cost about $3,000. The sad part is it is no longer covered under warranty as this drag often occurs in cars with 50,000 to 80,000 miles. This problem is common among 2002 to 2004 Honda CRV’s. Despite the number of complaints though, this cannot prompt a recall since it does not involve safety issues.
