This Tempstar heat pump review is where you can research models and their specifications as you compare this brand with Lennox, Trane, Carrier, Rheem and other leading brands we have reviewed. We include Tempstar pros and cons to consider before deciding on your next heat pump.

Tempstar is one of the brands made by International Comfort Products (ICP), which is part of United Technologies Corporation (UTC). The Tempstar catalog is identical to Heil and other ICP brands sold regionally in North America such as ComfortMaker, Arcoaire and KeepRite. UTC brands Carrier and Bryant are distinct from ICP brands.

Tempstar Heat Pump Brand Overview

Like many top heat pump brands, Tempstar makes three series that you can differentiate by efficiency and climate control features:

• Basic: Tempstar Performance Series (4 models);
• Better: QuietComfort Series (2 models);
• Best: QuietComfort Deluxe Series (3 models).

In the Things to Consider section below are general guidelines for choosing the right series/model for your application. These specifications will assist too.

Tempstar Heat Pumps Technical Specs

Here’s what you get with a Tempstar, starting with the top-of-the-line heat pumps.

• All QuietComfort Deluxe Series models (TVH8, TCH9, TCH6) and the TSH5 heat pumps are certified Energy Star models with at least 16 SEER/9.0 HSPF efficiency;
• The Tempstar TVH8 heat pump is the brand’s variable-capacity model with a compressor that modulates between 40% and 100% of capacity. It delivers quiet, precise and efficient heating and cooling;
• Other Deluxe Series models are Tempstar two-stage heat pumps that run on low most of the time for quieter, longer cycles. These produce more balanced temperatures than single-stage heat pumps;
• QuietComfort and Performance Series Tempstar heat pump models are single-stage units. They run on full capacity and can cause slight temperature fluctuations;
• Dual fuel heating systems with a heat pump and gas furnace are ideal for climates where winter temperatures often drop below freezing. This is a range in which heat pumps aren’t effective;
• ALL Tempstar heat pumps are dual-fuel compatible. The feature means that the system automatically switches to gas furnace heat when necessary and back to the heat pump when temperatures rise;
• The Deluxe 18 TVH8 runs as quietly as 56 decibels making it one of the quietest models available;
• Tempstar’s Observer communicating wall control is a Wi-Fi thermostat that supports QuietComfort Deluxe and QuietComfort Series.

Tempstar Heat Pump PROs and CONs

As a brand, Tempstar has a middle-of-the-pack reputation, but that’s where most brands are. Here are the benefits and disadvantages of choosing Tempstar.

Tempstar Heat Pump PROs

• Tempstar warranties are among the best on the market. Moreover, many include replacement of the entire heat pump if the compressor or condenser coil fails in the first 5-10 years, depending on model;
• The Wi-Fi Observer control for the Deluxe Series heat pumps gives you the option of monitoring and adjusting your heating and cooling remotely using a smart phone;
• The 4 Energy Star Tempstar heat pumps include single-stage, two-stage and variable-capacity models to fit your budget and performance preferences;
• Installing an Energy Star Tempstar heat pump might be eligible for utility rebates from your energy provider. So, ask your installer or search rebates;
• The three performance levels tend to match efficiency ratings – the highest-performing Deluxe 19 is also the most efficient. Therefore, heat pumps that run the most can also provide the best indoor climate control when you choose the right model for your climate;
• The 13.7 HSPF heating efficiency of the TCH9 two-stage Tempstar heat pump is among the very best in the industry. It is an ideal unit for cutting heating costs where winters are long;
• Tempstar uses a baked powder-coat finish on galvanized steel to produce an attractive case that resists corrosion and scratches;
• The Performance 14 NH4H4 Tempstar heat pump is a compact model for installation where space is limited and tight;
• The Performance 14 Coastal Design N4H4**C is one of just a few heat pumps designed to slow corrosion in the salt air of coastal communities;
• Tempstar manufacturers furnaces, air handlers and air purifiers. They provide integrated performance and optimal efficiency when combined with Tempstar heat pumps;
• Tempstar is a national brand. So, service and parts can be obtained wherever you live.

Tempstar Heat Pump CONs

• The most efficient models, the TVH8 variable-capacity and the TCH9 two-stage, have a SEER rating of 19. That is several points below the Lennox XP25 and other super-efficient heat pumps. So, these Tempstar models aren’t a top choice where summer heat and humidity are extreme;
• The loudest single-stage Tempstar heat pump models run at 69 decibels. The rate is slightly higher than the industry average for this class.

There’s not much to criticize with this and other ICP brands. They are well-made, efficient, reliable and competitively priced. Expect 15-20+ years of service from a Tempstar heat pump – the better the series, the longer it will run when properly maintained.

Things to Consider Before Purchasing a Tempstar Heat Pump

There are two keys to being satisfied with your Tempstar heat pump going forward. Choosing the right one for your needs and hiring a qualified installer with a track record of quality work.

1. The right heat pump for you will match the need for efficiency where you live. If summers and/or winters are extreme, then choosing an Energy Star-certified heat pump will keep energy use and cost under control. In those few areas of North America that have mild year-round climates, a 14-15 SEER model is sufficient since the unit won’t run much. This is true for heat pumps installed in part-time locations such as a guest apartment or vacation home. Reasons to choose a more efficient heat pump in mild climates are if you want the better comfort control of a two-stage or variable-capacity Tempstar heat pump or if lowering energy use as a means of living as green as possible is a high priority for you.
2. The second key to satisfaction, proper installation, is more crucial than the brand heat pump you select. We recommend getting estimates from several heating and air conditioning companies in your area that have a good reputation for quality and customer service. Talk to their representatives about the experience of the person or crew that will install your heat pump or HVAC system. That’s what is important. If the technicians are NATE-certified, that’s a plus.

These York furnace reviews are a buyers guide for those interested in this popular brand. It’s one of many furnace review guides of today’s top brands we’ve completed, including outlines of Lennox, Trane, Goodman, Rheem, and Amana.

York is one of a family of brands owned by Johnson Controls, a Fortune 100 and Global 500 company. Johnson Controls has its global headquarters in Cork, Ireland with 2,000 offices and facilities worldwide. Coleman and Luxaire are Johnson Control brands with identical products.

York Furnace Brand Overview

YORK EVCON 1 STG MULTIPOSITION 80,000 BTU 80% GAS FURNACE

• Evcon ( York ) RGF1L080BP12MP11 80,000 btu 80% natural gas furnace
• Items are new and unused in original box.
• 1 stage multi-speed multiposition (upflow.downflow, horizontal) natural gas furnace. 3 ton drive.

Check Price

You have a good variety of furnaces to choose from with York. If low equipment cost is important to you, York makes many affordable 80% efficient furnaces suited for climates with mild winters and for locations such as vacation homes that aren’t heavily used. Where winters are severe and efficiency counts, York’s furnaces with 90% to 98% efficiency will help you keep heating costs under control.

York furnaces also come in three performance levels:

• Single-stage 80% and 90%+ furnaces are the most affordable, but offer the poorest climate control;
• Two-stage 80% and 90%+ furnaces are quieter and produce temperatures that are more balanced than single-stage models can produce;
• Variable-capacity 95%+ York furnaces are the most expensive. Yet, they keep energy costs the lowest and produce the best climate control whether heating or supporting a central air conditioner in warm months.

York Furnace Technical Specifications

These technical specifications are an important part of York furnace reviews. They also allow you to compare them with other brands you’re considering.

• Like many leading brands, York makes good (Latitude Series with two models), better (LX Series with nine models) and best (Affinity Series with two models) furnaces;
• The Latitude Series gets the best York furnace reviews from consumers and industry experts;
• York makes six 80% AFUE (annualized fuel utilization efficiency) furnaces with models at all performance levels. The best 80% model is the variable-capacity Affinity Series YPLC;
• The brands’ seven furnaces with 90% AFUE and higher are mostly two-stage furnaces, though single-stage models. Some of them are the York TG9S and variable-capacity models like the Affinity YP9C with outstanding 98% AFUE are produced;
• York single-stage furnaces run at full capacity. So, temperature fluctuations of a few degrees and heating slightly past the thermostat set point, which wastes energy, are probable;
• Two-stage models run more quietly and heat more comfortably but cost more too;
• York variable-capacity furnaces deliver precise temperature control and use variable-speed blowers to optimize indoor comfort in all seasons;
• Four York furnaces including the York YP9C gas furnace are certified Energy Star furnaces. Also, they might be eligible for utility rebates or credits where you live;
• Most York 90%+ furnaces are built with secondary heat exchangers that capture more heat from the exhaust gases as they pass through;
• York’s ClimaTrak proprietary technology allows the installation technician to tune the furnace for your specific climate demands;
• Affinity Series and some LX Series models have an EPC fan motor, a type of motor that uses less energy than PSC motors.

PROs and CONs of York Furnaces

Here’s the good and bad points essential for complete York furnace reviews, a list of pros and cons that applies to Coleman and Luxaire brands too.

York Furnace PROs

• The York Affinity YP9C with 98% efficiency is on Energy Star’s list of the most efficient models in the industry;
• Having a variable-capacity furnace at 80%, not just in 95%+ models, gives homeowners in milder climates superior climate control;
• York’s lifetime heat exchanger warranty on its best models with a 10-year furnace replacement guarantee if the heat exchanger fails is a top-five warranty;
• Also, York’s standard 20-year heat exchanger and 10-year parts warranties are average for the industry. They are also better than Lennox and Trane offer on their base furnaces;
• ClimaTrak technology means that the performance of these furnaces can tune for better dehumidification during cooling cycles in very humid climates;
• Most brands require registration of a new furnace within 60 days to get the full warranty benefits. Yet, York gives consumers 90 days to register;
• York makes a range of compatible thermostat controls. This includes the York Affinity HX touchscreen, Wi-Fi thermostat;
• The most efficient York furnaces qualify for energy rebates and credits from energy companies across the country, and those benefits can be found here.

York Furnace CONs

• York has had slightly more reliability issues than other top brands like American Standard, Trane, Carrier, Bryant and Lennox in York furnace reviews. However, many of the bad York furnace reviews can be traced to poor installation techniques;
• The Affinity HX touchscreen, Wi-Fi thermostat offers convenience. But it is more expensive than popular Wi-Fi thermostats like nest and ecobee.

Things to Consider Before Purchasing a York Furnace

With York, you get average quality at a cost that is about average for the industry. You’ll pay more for American Standard, Lennox and the other superior brands mentioned but might get better reliability too. Cheaper brands like Goodman, Payne and Aire-flo cost less, but probably aren’t as reliable as York.

How efficient your new furnace should be is determined by climate and how long you plan to live in your current home.

• Where winters are mild, an 80% furnace is usually proper. This is because it would take 10+ years to recoup the higher cost of a 90% furnace through marginally lower heating bills. York makes single-stage, two-stage and a variable-capacity 80% furnace. So, you can choose the comfort level you’re willing to pay for.
• In a cold climate, a 95% or more efficient furnace is the key. They’re available in affordable single-stage, mid-priced two-stage and premium variable-capacity models. Even if you plan to live in your home a short time, a 95% furnace will be a selling point.
• The most important issue with gas furnace reliability, regardless of brand, is quality of the installation. To find a proven installer in your area, get estimates from several companies with a good reputation. Ask about the training and experience of the technician that will install the furnace. How long the company has been in business is irrelevant if the installer is a rookie.
• One final though on installation. Make sure the furnace you install has the proper size for your home. If you upgrade the insulation, install energy-efficient windows or if the new furnace is more efficient than the old one, the new furnace should be smaller. The technician can complete a Manual-J Load Calculation to most precisely size your furnace.

York Furnaces: Yes or No?

York, Coleman and Luxaire make decent-quality furnaces at average prices. If you’ve had success with York in the past, sticking with the brand makes sense. Be sure, as noted, to choose an installation company with expertise and experience.

WiFi thermostats are the future as smart-home technology and automation evolves. The WiFi thermostat models available now are the second or third generation from most manufacturers. Also, the control and convenience they offer along with easy setup and intuitive learning technology in some are very impressive.

If you’re just browsing this post and aren’t familiar with the basics of a WiFi thermostat, this introduction will be of help.

WiFi Thermostat Buying Tips

With dozens of quality models available, which WiFi thermostat is right for you? These five tips focus on functionality with some information about brands. Moreover, they’ll help you select a unit that will control your system to suit your lifestyle.

1. Set a Budget or Pick Your Features

• WiFi thermostats start at about $80 for basic models. One model is RTH6580WF Honeywell Wi-Fi thermostat with 7-day programming ($88).
• They range to more than $400 for full-color LCD touchscreen thermostats. One of them is the Lennox iComfort with 5-day forecast ($440).

Sticking to your budget will keep you from being lured into a higher price range for features that might be interesting or convenient but not essential. Most full-function WiFi thermostat models without a touchscreen or forecast cost $135 to $250. This includes popular thermostats like Nest (+/-$225) and ecobee ($170-$250).

If your budget has range to it, then decide if you want to pay extra for touchscreen ease and functionality.

2. Ensure Compatibility with Your HVAC System

Most WiFi thermostat models work with the 95 percent of HVAC systems that use low voltage, or 24 volts. If you have one of the few 110V systems still in use, indicated by wiring nut connections or the back of the thermostat stamped “110V,” then the system isn’t compatible with a WiFi thermostat.

If you have concerns about compatibility, there are two ways to check it:

• Buy a WiFi thermostat made by your HVAC brand, if one is available. There are many, including the Lennox iComfort, Carrier Côr, Bryant Housewise, Trane ComfortLink II and Heil Observer. Note that these thermostats work with other HVAC brands too. The issue isn’t the brand of the HVAC system or the thermostat. It’s the performance of your system such as single-stage, two-stage or variable, heating only, heating and air conditioning and humidity control.
• For thermostats not made by HVAC manufacturers, check compatibility on their site. Ecobee, Emerson Sensi and Nest are just a few of the WiFi thermostat makers that have this option. They allow you to determine if their thermostat is compatible with your HVAC system. You can check this simply by looking at the wiring connections on the back of your current thermostat. Go to the manufacturer’s website, find the compatibility checker. Then, select the letters corresponding to the wiring connections. The page will quickly determine compatibility. If you’re installing a system in new construction or tearing out an old system and thermostat, then your HVAC technician can assist you in determining compatibility.

3. Check for a Common Wire

A WiFi thermostat needs continuous power to remain connected, which is not the case with other thermostats. A wire known as a common wire or C-wire must be installed. Look at the “C” connection in or on the back of your thermostat to determine the presence of a common wire. If you don’t have one, there are four options:

• Install a C-wire. This is a single strand of the same type of copper wiring used to make the other thermostat connections.
• Replace all the thermostat wiring with new 18/5 5-conductor wire like this from Lowes.
• Install a Venstar Add-a-Wire adapter ($25-$35 from many retailers). This one requires installation in the furnace or air handler.
• Choose a WiFi thermostat like the ecobee3 that has a compatible power extender kit (PEK). The kit replaces the common wire ($20-$25).

In our opinion, the cleanest, most future-proof method is to run new 5-conductor wiring. An HVAC technician or electrician can install it or just a common wire for $100 to $200. The price depends on how accessible the current wiring is and the distance it will travel. The Venstar product makes sense when running new wire isn’t cost-effective. However, an electrician or tech will need about 30 minutes to install it for a minimum service fee of $75 or more.

Note: The Nest is one WiFi thermostat that doesn’t require a C-wire. However, its WiFi connectivity will be intermittent without one. Consequently, that will cause problems when attempting to control it remotely.

4. Choose a Programmable WiFi Thermostat that Fits your Schedule

Most programmable WiFi thermostats have one of three scheduling functions:

• 7-day: These thermostats give you the option of quickly programming every day the same. This is a great option for retirees with a regular routine. You can also program each day separately, so they’re a good choice if you work some weekdays but have others off.
• 5-2: Set one program for weekdays and one for weekends.
• 5-1-1: Saturday and Sunday are programmed separately.

Others, like the Carrier Côr and Nest use functional descriptions and motion sensors to control temperature. In the case of the Côr, you program Away, Home, Wake, Sleep and Vacation. You set the temperature you want for each function, and the thermostat uses sensors to determine, for example, whether you are home or away and for how long you’re away, at some point switching to Vacation mode if no motion is sensed.

Less important than the schedule is that you use programming. The US Department of Energy suggests that a programmable thermostat will reduce energy use and cost by 10 percent, but only when it is used. In 2009, the government Energy Star program stopped certifying programmable thermostats. They did this not because they don’t save energy but because most were so difficult to program that many people gave up. So they began using them like non-programmable models and losing the potential benefit.

The WiFi thermostat models with top ratings for easy setup and programming include:

• Honeywell Lyric;
• Emerson Sensi;
• Carrier Côr;
• Bryant Housewise;
• Nest;
• Ecobee Smart SI;
• LUX Geo.

If you have another WiFi thermostat in mind and want reviews that include ease of setup, see what buyers are saying about it at online retail sites.

5. Check Compatibility with Your Home Automation System or Amazon Alexa

The number of WiFi thermostat models that work directly with Alexa continues to grow. Here are the most popular Alexa-compatible WiFi thermostats at this writing:

• Nest;
• Ecobee3;
• Honeywell Lyric T5;
• Emerson Sensi;
• Carrier Côr;
• iDevices.

Many other WiFi thermostat models work with Alexa, Apple HomeKit and/or with a home automation system through hubs. Some of them are Samsung SmartThings, Insteon, Wink Hub 2, Iris Smart Hub, Logitech Harmony Elite and Smart Home. Check the website of the automation equipment manufacturer or the thermostat manufacturer to ensure compatibility and find instructions on setting up the WiFi thermostat on the system.

Buy, Read and Learn

While the ease of use for WiFi thermostats has improved, there is still a learning curve. After you purchase your WiFi thermostat, download the app and read the enclosed literature. Watch demo videos on the manufacturer’s site. Most WiFi thermostats aren’t difficult to use; they’re just unfamiliar and new. You’ll soon master the thermostat, the app and any home automation applications it integrates with.

Other readers would enjoy hearing your experience with a WiFi thermostat, if you’d come back to share what you bought and your opinion of it. And please pass along this information to your followers and friends. They might be looking for tips on how to buy the right WiFi thermostat too.

Our Lennox heat pump buyer’s guide is your source for comprehensive and accurate information about Lennox heat pump models. We’ve produced guides for other brands for you to compare pros & cons, top heat pumps from each and their technical specifications. See guides for these brands and more:

• Trane heat pumps;
• Goodman heat pumps;
• Carrier heat pumps.

Lennox is on a mission to produce the most energy-efficient HVAC equipment. Its top heat pump, the Lennox XP25, its top air conditioner (XC25) and gas furnace (SLP98V) lead the industry. This brand is unique in that Lennox makes its own replacement parts, and we’ll have more to say about that later.

Lennox Heat Pump Brand Overview

There are seven Lennox heat pump models divided into three series:

• Best: Dave Lennox Signature Collection: 3 models;
• Better: Lennox Elite Series: 3 models;
• Basic: Lennox Merit Series: 1 model.

The differences give you options ranging from affordable, basic units to costlier high-performance Lennox heat pumps.

Lennox Heat Pumps Technical Specifications

Let’s dig deeper into the seven Lennox heat pump models:

• Lennox makes single-stage models, two-stage and variable-capacity heat pumps;
• Single-stage Lennox Merit Series 14HPX delivers 16 SEER air conditioning and 8.2 HSPF heating. Also, it is the most efficient base model in the industry;
• Three Lennox Elite heat pumps are the single-stage 16 SEER/9.5 HSPF Lennox XP14, the two-stage 17 SEER/9.5 HSPF XP16 and the top pick, the modulating XP 20. It has a 20 SEER/10 HSPF efficiency, all Energy Star rated;
• Three Signature Series heat pumps are Energy Star rated, the single-stage SL18XP1 (18.5 SEER/10.2 HSPF), the two-stage XP21 (19.2 SEER/9.7 HSPF) and the variable-capacity XP25 (23.5 SEER/10.2 HSPF);
• The two variable-capacity models, XP20 and XP25, have compressors that fluctuate from 40% to 100% of capacity like cruise control. This is to keep temperature precisely balanced. It aims to also remove more humidity during air conditioning than single- or two-stage units;
• Several Lennox heat pump models (14HPX, XP14, XP16, XP21 and XP25) are dual-fuel compatible which means they can be installed in a split system with gas furnace. Consequently, the heat pump will provide the heating in temperatures above freezing and the furnace will automatically take over in colder temperatures.

Pros and Cons of Lennox Heat Pumps

There are plenty of reasons to consider Lennox and few potential disadvantages too.

Lennox Heat Pump Pros

• This is the most efficient lineup of heat pumps on the market. So, your energy use and cost can reduce by 30 to 60 percent when replacing an old heat pump;
• Single-stage, two-stage and variable-capacity models give you options to match your indoor comfort preferences and budget;
• The diverse range of efficiency levels allows homeowners to match their heat pump choice to their climate. They can also support their commitment to heat and air condition their homes with eco-friendly technology;
• Lennox makes compatible components for its heat pumps. This includes air handlers, gas furnaces, HRV and ERV ventilation units, indoor air quality systems, humidity control systems and thermostat controls for complete, coordinated split systems;
• Lennox Elite Series and Signature Collection heat pumps are well built. They should last 17-22 years when properly maintained;
• The SL18XP1 is the industry’s most efficient single-stage model. So, it provides premium efficiency at a lower cost than most two-stage heat pumps;
• Six of the seven Lennox heat pump models are certified by Energy Star. They also might be eligible for utility rebates from your energy provider;
• Dual fuel Lennox heat pumps installed in a split system with a Lennox gas furnace are an ideal choice for climates where freezing winter temperatures are common;
• Lennox SunSource solar modules can produce enough energy to run a complete HVAC system.

Lennox Heat Pump Cons

• The brand makes its own replacement parts, and they are mostly of superior quality. But periodic supply-chain problems cause delays in repair times;
• There seems to be an issue with the quality of some Lennox coil models, with a large number of reported failures. Also, it is unclear whether the quality-control issue has been resolved;
• A Lennox heat pump will cost more than most comparable models. Part of the higher cost is superior quality, but it is partly due to brand recognition and an expensive marketing program;
• While SunSource modules reduce energy cost, they are expensive. Also, the payback time could be 12 years or more in some climates;
• Lennox heat pump warranties are not as long or comprehensive as those from Amana, Goodman, Heil, Arcoaire, Comfortmaker, Maytag, Tappan and several other brands.

Things to Consider Before Purchasing a Lennox Heat Pump

Your first consideration is climate. The more extreme your climate is, the more efficient the Lennox heat pump you choose should be. Where winters are harsh, a heat pump alone is a poor option. This is because you’ll use space heaters to stay warm, and they produce costly heat. If your winter weather is often freezing, then a gas furnace alone or a dual fuel heat pump and gas furnace combination is a better choice. A dual fuel system costs more upfront but produces the lowest heating costs.

With single-stage, two-stage and modulating heat pumps available, whether you’re willing to pay more to get improved climate control is a consideration. Your costs rise 10-15 percent with each step up in performance.

Be sure your heat pump is properly sized for your home. Some HVAC technicians oversize the units. But that leads to imbalanced temperatures and higher incidences of mechanical failure. Ask that a load calculation be done. Also, if your home’s insulation has been increased, most commonly in the attic, or if energy-efficient windows have been installed since the last heat pump was purchased, it’s possible the replacement Lennox heat pump should be smaller than the original.

Invest in Quality Installation

Take time to find a qualified installer for your heat pump. Moreover, installation quality is essential to the durability, efficiency and performance of your HVAC system. We suggest getting written estimates from several licensed and insured installers to find one with skill and experience.

This Lennox furnace buyers guide is designed to inform our readers about one of the industry’s best-selling brands. We’ve included the good and the bad of Lennox furnaces plus the best models in each class. This Lennox furnaces review can be used to compare this brand with other brands we’ve reviewed including Amana, Trane, and Goodman.

In 1895, Dave Lennox designed and manufactured the industry’s first riveted-steel furnace. In 1935, Lennox introduced forced-air heating systems. This history of innovation continued, and so did expansion as Lennox International developed a global reach. A public company since 1999, Lennox owns several other HVAC brands such as Armstrong Air and Ducane. They all have different product lineups.

Lennox Furnaces Brand Overview and Lennox Furnace Reviews

The current catalog of 10 Lennox furnaces are divided into three series in basic/better/best quality by our Lennox furnace reviews:

• Best – Dave Lennox Signature Collection: 2 models;
• Better – Lennox Elite Series: 5 models;
• Basic – Lennox Merit Series: 3 models.

Another way to look at the lineup is by dividing Lennox furnace models by efficiency and performance:

• Efficiency: 80% AFUE furnaces and 90%-plus AFUE furnaces;
• Performance: 5 single-stage furnaces from the Merit and Elite Series; 3 two-stage furnaces in the Elite Series; 2 variable-capacity furnaces in the Signature Series.

Lennox Furnaces Technical Specifications

Here’s a closer look at what the various Lennox furnace models offer:

• The four Lennox 80% AFUE furnaces have single heat exchangers. So they transfer an inefficient 80% of the heat they create into your home’s ductwork;
• Lennox single-stage 80% furnaces are affordable. But they run on full capacity and might heat past the thermostat setpoint;
• Lennox mid-price and high-price two-stage models run on low capacity most of the time for more balanced heating;
• The top pick among the 80% furnaces is the Signature Collection Lennox SL280V with a two-stage gas valve;
• Lennox 90% and higher efficiency furnaces are found in all series. They have an efficiency as high as 98.7% in the top-pick Signature Collection SLP98V;
• The 90%-plus furnaces include single-stage, two-stage and the variable-capacity (with variable-speed blower) SLP98V. This one modulates in 1% increments up and down to meet the exact heating needs in the home;
• The SLP98V, EL296V, EL296E and EL195E have secondary heat exchangers. They allow these Lennox furnaces to utilize a higher percentage of the heat created for heating your home;
• Most Lennox furnace models have units in a range from about 50,000 BTU to about 140,000 BTU capacity.

Pros and Cons of Lennox Furnaces

Knowing Lennox furnace advantages and disadvantages will assist you in comparing Lennox with other leading brands as you consider options.

Lennox Furnace PROs:

• Because Lennox makes such a wide range of furnaces, you’re able to put together the right combination of efficiency and performance;
• Lennox is typically among the top 10 brands in terms of customer satisfaction and mechanical reliability;
• Lennox is a national brand. So finding a certified Lennox dealer and repair technician isn’t a problem;
• The SLP98V and Lennox SunSource solar is a great combination for homeowners who want the greenest heating possible;
• Choosing a 90%-plus Lennox furnace might cut energy use by 20% to 30% when replacing an old gas furnace;
• Furnaces are available in upflow, downflow and horizontal configurations;
• Since Lennox makes furnaces, ACs, heat pumps, whole-house dehumidifiers, ventilation products and thermostat/controls, it’s possible to install an entire HVAC system designed to work together;
• Like all brands’ Energy Star furnaces, those made by Lennox might be eligible for rebates and credits from your utility company;
• While Lennox makes thermostats, most Lennox furnaces can be controlled by other brands including White-Rodgers thermostats;
• Lennox makes dual fuel heat pumps that can be installed with a gas furnace for the most efficient split-system heating option;
• Also, Lennox makes most of its own replacement parts, so their quality is assured.

Lennox Furnace CONs

• Lennox HVAC systems including furnaces are among the most expensive on the market;
• While using proprietary replacement parts ensures quality, the parts cost significantly more than standard replacement parts. So repairs are pricier;
• A second disadvantage of the proprietary parts issue is that Lennox sometimes has supply chain problems that make parts hard to get, slowing repairs by days or weeks;
• Lennox warranties are not as good across the entire product line, especially just 5 years on parts in the Elite and Merit Series, as warranties from competitors like Amana, Heil, Maytag and Goodman.

Things to Consider Before Purchasing a Lennox Furnace

Are you buying based on climate or your commitment to the environment? If the former, then the colder your climate is, the more cost-effective a 90%-plus furnace is. The extra cost over an 80% furnace will recoup through lower energy bills in 3-10 years depending on your climate and the specific furnace you choose. It’s also true that the longer you plan to stay in your home, the more sense it makes to buy a highly efficient furnace. An efficient furnace is a good selling point if you do put your home on the market.

If the environment is at the top of your criteria for choosing a gas furnace, then the solution is to buy one of the Lennox furnaces with 95% or higher efficiency. The Elite Series EL195E and Merit Series ML195 are affordable single-stage, 95% AFUE models; the two-stage EL296V at 96% AFUE and the variable-capacity SLV98P at 98.7% AFUE offer better performance at a higher cost.

The three performance levels – single-stage, two-stage and variable-capacity – give you cost vs. performance options at all efficiency levels. Do you want to pay more for enhanced indoor comfort? Would you prefer to pay less and put up with minor temperature fluctuations and a bit more humidity in summer? Either way, there are Lennox furnaces to suit your style.

Is a Lennox Furnace Right for You?

If you’re willing to pay a premium for better quality and reliability, with the chance of having your furnace down for a week or more should it fail during a winter cold snap, then consider Lennox. If you want a comparable brand with quicker repairs, Amana, Trane, Carrier and Bryant are a few to look at too.
