Review of Lennox’s Strengths and Limitations

Strong Points

Lennox has provided top quality HVAC products for over a century. Their premium models, primarily found in the Dave Lennox Signature Series, are industry leaders when it comes to efficiency, with some models able to operate at 99 percent AFUE.

Their furnaces are also built to a high standard with exceptional materials, ensuring durability and reliability, even during periods of heavy usage.

Lennox focuses on making furnaces that are extremely quiet, efficient, and reliable. They have a good selection of high-efficiency furnaces with a decent range of design elements, including single-stage, two-stage, and modulating furnaces paired with constant torque or variable-speed blower motors.

Regardless of where you live or the heating demands of your home, you'll probably find something in Lennox’s product line to meet your needs.

Room For Improvement

When compared with other brands, especially more budget-friendly ones, Lennox can be found wanting in one or two areas, including the warranty coverage they offer on all their models.

Some of their entry-level units only come with a 20-year heat exchanger warranty, none of their furnaces have a parts warranty longer than 10 years, and they don’t offer the unit replacement warranties that have recently been adopted by many other brands.

Furthermore, Lennox doesn’t have a lot of novel features or technologies, especially when compared to premium brands like Carrier, who have Greenspeed Intelligence, the Ideal Humidity System, Smart Evap, and more, or even compared to economy brands like Goodman that have communicating technology like ComfortBridge.

Another thing about Lennox is that they're considered a premium brand, and that means you'll pay a premium price for one of their furnaces. It is possible to get an entry-level Lennox furnace at a reasonable price, but if you want a mid-range or top-tier model, then expect to pay around $7,000.

The Bottom Line

Lennox set themselves apart from the competition by delivering high-end heating solutions. They make reliable and well-designed options at different price points, and the company covers a lot of ground within the HVAC marketplace with both entry-level and premium-tier models.

Lennox markets themselves as the top-tier, brand name company in heating and cooling, and they have an excellent reputation. Their main focus is high-end furnaces that are efficient and quiet, and if you don’t mind paying a higher price for the name, then Lennox might be a good brand to consider.

Alternatively, if you're interested in things like economy, better warranties, and cool features, then you might want to look at some competitors instead.

While it’s certainly debatable whether paying a premium price for a top-tier furnace is worth it, homeowners generally won’t be disappointed as long as they can afford the relatively high price point.

Lennox Average Price Range

$3,500 – $7,500 (including installation)

It’s difficult to set an exact price as manufacturers or local distributors may often promote deals on certain units throughout the year, and government or utility company rebates may be available as well.

With any furnace, the final cost of the unit will vary based on where you live, the model you choose, your home size and the unit’s installation, and the tier of furnace you want.

Lennox has entry-level Merit series furnaces, mid-range Elite series furnaces, and top-tier Dave Lennox Signature Collection furnaces. Furnace price ranges increase as you go up in tier, and the higher the tier, the more perks the furnace will have, such as better features and longer warranties.

Here's an estimate of Lennox furnace tier price ranges:

• Entry-level models: $3,500 – $4,835
• Mid-range models: $4,835 – $6,170
• Top-tier models: $6,170 – $7,500+

Lennox Furnace Model Series Overview

Basic – Merit Series

The entry-level Merit series includes Lennox’s most affordable offerings. The models in this tier include single-stage furnaces with constant torque blowers and two-stage, variable-speed furnaces with AFUEs of 93 or 96 percent.

Some of the Merit furnaces have ENERGY STAR® certification, and some are even more affordable, sophisticated, and efficient than a few of the pricier mid-range Elite models. One trade-off, however, is that they only have a 20-year warranty for the heat exchanger.

They also have tightly sealed blower compartments to reduce air leakage, secondary heat exchangers to reduce heat loss, Lennox’s proprietary Duralok Plus primary heat exchangers, and they're all dual fuel capable, meaning they can be paired with an electric heat pump to save more money and energy.

Some models in the Merit series are compatible with Lennox’s iComfort M30 smart thermostat, which can give you access to some additional features and capabilities that aren't available with the furnace alone.

All the furnaces in this series are built with heavy-duty components and materials that are made to last. They're also backed by decent warranties, so if anything should happen, you know your investment will be covered.

Better – Elite Series

The mid-range Elite Series contains single- and two-stage furnaces with constant torque motors and more advanced two-stage, variable-speed furnaces. They have efficiency ratings of 95 and 96 percent, and all of them are ENERGY STAR certified. There's also an ultra-low nitrogen oxide emissions model in this tier.

Elite series furnaces do come with a higher price tag than their Merit counterparts, in part because they come with a longer lifetime heat exchanger warranty. However, they have all the same design features, including Duralok Plus primary heat exchangers, secondary heat exchangers, insulated blower compartments, and dual fuel compatibility.

These models are compatible with a more sophisticated smart thermostat, the iComfort E30, which has even more capabilities than the M30.

Best – Dave Lennox Signature Collection

The top-tier Dave Lennox Signature Collection includes some of the finest furnaces ever produced by Lennox, and the most efficient furnace on the market today.

There are two-stage and modulating furnaces in Lennox’s premium tier, and they have variable-speed blowers and AFUE ratings of 97.5 to 99 percent. One even qualifies as an ultra-low NOx furnace.

Plus, they have all the same attractive design elements as other Lennox furnaces, including the Duralok Plus heat exchanger, condensing operation, extremely quiet performance, and dual fuel capability.

Dave Lennox Signature Collection furnaces are some of the most expensive on the market, but they don’t come with a better warranty than the Elite series models. Further, they don’t have any additional technological features, aside from being compatible with the iComfort S30, Lennox’s most advanced smart thermostat.

Model Breakdown and Comparison

Dave Lennox Signature Collection SLP99V

The SLP99V is the most fuel-efficient furnace on the market and was awarded the ENERGY STAR Most Efficient 2021 certification. It has a 99 percent AFUE, boasting nearly zero energy waste. Not only is it the most energy-efficient furnace available, but it’s also the quietest (and among the most expensive). This modulating furnace has variable-speed operation, a secondary heat exchanger, and other great design features that make Lennox furnaces quiet and reliable. Plus, you can unlock even more great features if you pair it with the iComfort S30 smart thermostat. No matter where you live or what size your home, the SLP99V will have no trouble keeping the house consistently warm, the moisture levels balanced, and the energy bills down. Let’s have a look at the design specifications of the SLP99V:

AFUE: 99 percent
Furnace type: Modulating
Blower type: Variable-speed
ENERGY STAR® rated? Yes
Tier – Best
Ideal for: Homeowners with a very healthy budget who want a brand name furnace that will save the most amount possible on heating bills. The SLP99V doesn’t have a lot of features or technologies, but it’s quiet, extraordinarily efficient, reliable, and built to last.

Dave Lennox Signature Collection SL297NV

The SL297NV is another top-tier furnace from Lennox.  It’s a two-stage furnace with a variable-speed blower that promises excellent efficiency, quiet performance, and consistent temperatures throughout the house, all winter long. The SL297NV was awarded the ENERGY STAR Most Efficient 2021, has ultra-low NOx emissions, and it reduces nitrogen oxide emissions by 65 percent compared to low NOx furnaces, making it the lowest emissions furnace on the market.  It’s also equipped with Lennox’s standard design elements, including a secondary heat exchanger, the Duralok Plus primary heat exchanger, an insulated blower compartment, and iComfort S30 compatibility. Here's a closer look at the SL297NV’s specifications:

AFUE: 97.5 percent
Burner type: Two-stage
Blower type: Variable-speed
ENERGY STAR rated? Yes
Tier – Best
Ideal for: Canadians who are concerned about the environment, energy-efficiency, and home comfort, but who also have a large budget for a furnace upgrade. The SL297NV is a highly efficient furnace that’s also quiet and reliable, and because it boasts such low NOx emissions, it’s also a great choice for the planet.

Lennox Elite EL296V

The EL296V is an impressive two-stage unit that can operate at two different heat output intensities, helping to eliminate temperature swings in your home and allowing improved control over the humidity levels in your home. Although a two-stage operation is not as effective as a modulating unit like the SLP99V, the EL296V is still a very efficient and capable furnace that shouldn’t have any trouble keeping every corner of your home warm. Furthermore, while this model isn't quite as efficient as Lennox’s premium models, it still has great design features and a high-efficiency rating that will save you plenty on heating bills. This is what the design features of the EL296V include:

AFUE: 96 percent
Burner type: Two-stage
Blower type: Variable-speed
ENERGY STAR rated? Yes
Tier – Better
Ideal for: People with moderate to high heating demands who want an efficient and quiet furnace that comes with the backing of a trusted brand name. This model will still require a significant investment, but it’s a little more affordable than Lennox’s premium-tier models.

Lennox Elite EL296E

The EL296E is very similar to the EL296V in that it’s a two-stage furnace with an AFUE of 96 percent and ENERGY STAR certification, but this model has a slightly more basic constant torque motor. That means it has a couple of airflow speeds, but it can't make incremental adjustments to the airflow the way a variable-speed blower can. Nonetheless, the EL296E still has a secondary heat exchanger, proprietary primary heat exchanger, and great efficiency rating, so it promises quieter performance, more cost-effective operation, and better heat distribution than a single-stage or single-speed furnace. Here are the specifications you'll want to know about:

AFUE: 96 percent
Burner type: Two-stage
Blower type: Constant torque
ENERGY STAR rated? Yes
Tier – Better
Ideal for: Anybody looking for a furnace upgrade who has a healthy budget, wants a brand name furnace, and doesn’t mind paying extra for a heating system that’s efficient, quiet, and reliable, but that doesn’t have too many extra bells and whistles.

Lennox Elite EL196E

Despite being a relatively pricey mid-range furnace, the EL196E is arguably a little basic. It has a high-efficiency rating of 96 percent, ENERGY STAR certification, and a secondary heat exchanger, but it only has single-stage operation paired with a constant torque motor. It is, however, compatible with the iComfort E30 smart thermostat, so you can get additional features like voice control if you integrate it with an additional technology like Amazon Alexa or Apple HomeKit. This is what you need to know about the EL196E:

AFUE: 96 percent
Burner type: Single-stage
Blower type: Constant torque
ENERGY STAR rated? Yes
Tier – Better
Ideal for: People in smaller homes, in warmer parts of the country, or who don’t mind a cooler home in winter. The EL196E will still save plenty on energy bills, but the single-stage operation and constant torque motor make it better equipped to warm homes with lower winter heating demands. You'll still need a rather large budget to afford this furnace, and it might not qualify for as many rebates as furnaces with more sophisticated design elements.

Lennox Elite EL195NE

The Elite EL195NE is Lennox’s mid-range, high-efficiency furnace with ultra-low NOx emissions. Like the other low-NOx furnaces from Lennox, it boasts 65 percent lower emissions than standard low-NOx furnaces. Like Lennox’s other furnaces, it has a secondary heat exchanger and other design elements to improve efficiency, but it has a slightly lower 95 percent AFUE, a single-stage burner, and a constant torque motor. These are the details about the EL195NE that you might want to know:

AFUE: 95 percent
Burner type: Single-stage
Blower type: Constant torque
ENERGY STAR rated? Yes
Tier – Better
Ideal for: Canadians who want to lower their energy bills while also reducing their environmental impact. Thanks to the high-efficiency performance and ultra-low NOx emissions, this furnace will keep smaller homes with lower heating demands warm while also reducing fuel use, heating bills, and greenhouse gas emissions.

Lennox Merit ML296V

The ML296V may be one of Lennox’s entry-level furnaces, but that doesn’t stop it from promising excellent efficiency and performance, thanks to the two-stage operation, variable-speed blower motor, and secondary heat exchanger. These features also deliver better humidity control, more consistent temperatures, and improved energy efficiency, which translates to more money in your pocket at the end of each winter. Plus, the ML296V is compatible with the iComfort M30, which can give you access to a few more cool features. However, as a Merit series furnace, it does have a shorter warranty than other Lennox products. Let’s look at what makes this model so appealing:

AFUE: 96 percent
Burner type: Two-stage
Blower type: Variable-speed
ENERGY STAR rated? Yes
Tier – Basic
Ideal for: Canadians looking for a furnace that offers a little better value for what they pay. The ML296V still carries the prestigious Lennox name, and it has great design features and efficiency, and it’s also more affordable than other Lennox furnaces because it’s an entry-level model.

Lennox Merit ML196E

The ML196E is an efficient, ENERGY STAR furnace with a good AFUE, decent warranty, and good design features. It’s also a little more affordable than most other Lennox furnaces because it’s an entry-level, single-stage model. It can be paired with the iComfort M30 for some additional features, but it’s still a fairly standard high-efficiency furnace. Let’s look at the important stats for the ML196E:

AFUE: 96 percent
Burner type: Single-stage
Blower type: Constant torque
ENERGY STAR rated? Yes
Tier – Basic
Ideal for: Homeowners who like the appeal of the Lennox name without having to pay an arm and a leg for it. This single-stage model will also be better suited for homes with lower heating demands, such as townhouses, smaller homes, apartments, or places in milder parts of the country.

Lennox Merit ML193E

The ML193E is Lennox’s most affordable furnace, but with an AFUE of 93 percent, it’s also their lowest-efficiency furnace that still qualifies as high-efficiency, and their only high-AFUE furnace without ENERGY STAR certification. At the same time, it does have some appealing design elements, including a secondary heat exchanger, insulated blower compartment, dual fuel compatibility, and a constant torque motor that’s superior to a single-speed one. This model won’t save you quite as much on energy bills as a more efficient alternative, but it will still cut your heating bills if you're upgrading from a low- to mid-efficiency unit. Here are the details about the ML193E you'll want to know:

AFUE: 93 percent
Burner type: Single-stage
Blower type:Constant torque
ENERGY STAR rated? No
Tier – Basic
Ideal for: Homeowners who don’t have a huge budget for a furnace upgrade but who still want a prestigious name and a reliable and high-efficiency unit. A furnace like this is also best for people who aren't interested in novel features and aren't concerned about rebate eligibility, heating a large home, or lengthy warranty coverage.

Exclusive Features from Lennox

Feature 1 – Power Saver™

How Lennox describes it: A constant torque motor that uses less energy to heat and cool your home, thereby reducing your utility bills.

What it is in plain language: The blower motor in a furnace refers to the motor that powers the blower that actually blows air into the ductwork to circulate around your house. A constant torque blower motor is a type of motor that has more than one speed, typically five, so it can adjust the airflow depending on the conditions and your heat settings.

Is it more than just hype? The name Power Saver isn't quite deceptive, but it is an example of Lennox just giving a fancy name to a specific type of blower motor. At the same time, constant torque blowers are superior to single-speed ones, and they can in fact reduce energy bills while improving humidity management, lowering operational noise, and providing more even heat throughout your house.

Lennox seems to be doing away with single-speed blowers and moving toward ones with multiple and variable speeds, and this is good for your home comfort and your energy bills. But it should be noted that a lot of HVAC brands are making this move, so Lennox isn't exclusive in this.

Feature 2 – iComfort Smart Thermostat

How Lennox describes it: A smart thermostat that will help you maximize the performance of your heating and cooling systems. These products are flexible, adaptable, and can save you money on energy bills.

What it is in plain language: iComfort is actually a collection of proprietary smart thermostats from Lennox. The iComfort S30 is compatible with Dave Lennox Signature series heating systems, the iComfort E30 is compatible with Elite furnaces and some non-Lennox furnaces, and the iComfort M30 is for Merit and some other non-Lennox furnaces.

As a smart thermostat, the iComfort products are Wi-Fi enabled thermostats that can learn your behaviours, create heating schedules based on your routines, and give you remote access to your heat settings and other data.

Is it more than just hype? Lennox isn't the only HVAC company that makes their own smart thermostats, and here's a list of some others: Carrier Armstrong, Heil, KeepRite, Comfortmaker, Tempstar, Rheem, Ruud, Trane, York, Coleman, Luxaire, and Daikin.

There's good reason that so many HVAC manufacturers make their own smart thermostats, and one is the fact that these devices can in fact save a great deal on energy bills.

Furthermore, the iComfort smart thermostats do have some really cool features that not all HVAC controls have. The specific features available depend on whether it’s the S30, E30, or M30, but here are a few of the capabilities you might like:

• When paired with technologies like Alexa, IFTTT, and HomeKit, you can get voice control access to your thermostat
• The thermostat can monitor outdoor air quality and make automatic adjustments to preserve your indoor air quality
• The device actively monitors your furnace and can send automatic updates to your HVAC technician
• It has a geofencing feature that can automatically put your furnace into an energy-saving away mode or your programmed comfort mode depending on whether you're home or away.

Feature 3 – Duralok Plus

How Lennox describes it: A heat exchanger that’s used in Lennox’s high-efficiency condensing furnaces. It’s superior to standard heat exchangers because it has a clamshell design, has a condenser coil assembly, and is made from patented ArmorTuf steel.

What it is in plain language: The heat exchanger is the heart of a furnace, and the Duralok Plus heat exchanger is special for two reasons: the design and the material. Clamshell heat exchangers don’t rely on welding to keep joints together, and ArmorTuf steel is a patented metal, so the Duralok Plus design is exclusive to Lennox.  

Is it more than just hype? Clamshell heat exchangers tend to have a longer life because they're less likely to crack or separate, and ArmorTuf steel has a special corrosion-resistant finish that can give it a longer life than regular steel. In other words, there's a good chance that a Duralok Plus heat exchanger could last longer than a standard one.

While the Duralok Plus design is exclusive to Lennox, they aren't the only company that has their own proprietary heat exchanger. Other examples include Armstrong’s EHX Technology, Napoleon’s Vortex Turbulator, and Heil’s, Tempstar’s, and Comfortmaker’s RPJ heat exchangers.

Feature 4 – Ultimate Comfort System

How Lennox describes it: A whole-home comfort system unlike any other that’s finely tuned to your home to provide clean indoor air.

What it is in plain language: The Ultimate Comfort System isn't so much a special feature as it is a collection of different technologies that can be paired with Lennox’s premium Dave Lennox Signature Collection models.

The system combines their iComfort S30 thermostat, PureAir S air purification technology, iHarmony zoning capabilities, and other devices to optimize home comfort and indoor air quality.

Is it more than just hype? The Ultimate Comfort System has the potential to improve your indoor air quality because it uses things like the iComfort S30, which tracks outdoor air quality and adjusts the fan settings to maintain good indoor air quality.

At the same time, achieving the Ultimate Comfort System requires purchasing quite a few additional technologies, including the iComfort S30 and the PureAir S system. Similar results could be achieved with just about any whole-home air purification system or air cleaner.  

Warranty Analysis

The warranty terms

Furnaces in the Dave Lennox Signature Collection and Elite series come with a lifetime heat exchanger warranty and a 10-year parts warranty.

However, Merit series furnaces come with a 10-year parts warranty and a shorter 20-year heat exchanger warranty.

Registration is required

For Elite and Merit furnaces, you must register the furnace after installation, and there's a 60-day deadline if you want to be eligible for the full warranty terms. Should you fail to register, then the parts warranty will only be valid for five years.

Fortunately, the registration process is quite simple, and you can do it online through the Lennox website. Here's what you'll need:

• The serial and model numbers
• The date of installation
• The name and address of the installer
• The brand, serial number, and model number of your other HVAC components
• Your email address

Registration is a very common requirement among HVAC manufacturers, and most have unregistered warranty terms and extended terms for registered units. However, Lennox is unique in asking for details about your other HVAC system components.

Conditions and restrictions

Beyond having to register your new furnace to take advantage of the full warranty terms, there are also other conditions you'll have to abide by to keep the warranty valid.

One of the most common conditions is requiring that the furnace be installed by a licensed HVAC professional. In other words, if you try to install the furnace yourself, then you risk voiding the warranty.

Another common warranty obligation is that you take care of regular annual maintenance. If you're not sure what type of maintenance is required, then check the owner’s manual or the warranty conditions for details.

How the Lennox warranty measures up to the competition

While you might expect Lennox to offer better warranty terms than other brands, the truth is they don’t. Even though they charge more for their furnaces than most other manufacturers, they still have one of the most basic warranties in the industry.

One area where Lennox is lacking is the unit replacement warranty. A number of economy and mid-range brands have started offering these, which means the manufacturer will provide a brand new furnace if the heat exchanger fails during the coverage period. Here are some examples of brands that offer this type of protection: Comfortmaker, American Standard, York, Trane, Tempstar, Ruud, Rheem, Coleman, Napoleon, Luxaire, Amana KeepRite, Heil, Goodman, and Daikin.

Moreover, several brands offer lifetime heat exchanger warranties on all their high-efficiency furnaces, including their entry-level models. Brands that offer this level of coverage include Luxaire, Goodman, Daikin, Coleman, American Standard, and Amana (either through their unit replacement or heat exchanger warranty).

In fact, Armstrong Air, which is owned by the same parent company as Lennox, Lennox International, even offers a lifetime heat exchanger warranty on all their high-efficiency models.

Lennox’s Add-ons, Extras, and Thermostats

Programmable Thermostats

On top of their iComfort smart thermostats, Lennox also makes more basic programmable thermostats called ComfortSense. These devices allow you to program different temperature settings for various times of day and days of the week depending on whether you're home, away, or asleep.

Depending on the specific model, ComfortSense thermostats have capabilities like energy-saving away modes, filter maintenance reminders, dual fuel operation, and energy reports.

Programmable thermostats can indeed save you money, but they lack the benefit of remote operation because they aren't Wi-Fi compatible. They also rely on your programmed schedules, meaning they don’t learn your habits and adapt the way some smart thermostats can.

Zoning Systems

For homes that have different temperature needs in various parts of the house, you can consider a Lennox Harmony zoning system that works in conjunction with a smart or programmable thermostat.

Lennox has two- and four-zones systems that can monitor and maintain different temperature settings in two or four separate parts of the house.

These can be great for large homes, tall homes where lots of heat rises quickly, homes with rooms over cold garages, homes with sunrooms, or families who have different ideas of what a comfortable temperature is.

Air Purifiers

Lennox has a number of products that improve indoor air quality, including air purifiers, media air cleaners, HEPA filters, and UV germicidal lights. Products like this can be beneficial if you deal with a lot of wood smoke or pollution, have family members with allergies or lung disease, or are just concerned with indoor air quality.

Lennox air purification systems include the PureAir and PureAir S systems, which can clean the air of viruses, bacteria, fungi, ozone, odours, smoke, mold, pollen, dust, volatile organic compounds, and more.

They also have media air cleaners with MERV 11, 13, and 16, and these remove allergens, dust, pollen, and up to 95 percent of germs. Their hospital-grade HEPA filter is even more powerful, capable of eliminating up to 99.97 percent of particles as small as 0.3 microns.  

Finally, their UV germicidal light can clean the air in your home and keep your ductwork and HVAC systems cleaner by killing germs, fungi, and mold. As such, UV lights can potentially help to preserve the efficiency of your furnace and air conditioner and possibly extend their life expectancies.

Humidifiers and Dehumidifiers

Too little moisture in the air in your home can dry out wood and cause cracking, but it can also lead to dry skin, sore throats and noses, and static electricity that leads to shocks.

When you have problems with low humidity, a humidifier can add moisture to the air and eliminate the problems associated with dry air. Furthermore, air with some moisture in it can also feel warmer, so a humidifier could take some of the burden off your furnace in winter.

On the other end of the spectrum, air that has too much moisture can lead to mold growth, and it can also cause moisture damage to wood, walls, floors, ceilings, and paint. Plus, humid air can force your air conditioner to work harder in summer.

Lennox has a number of whole-home humidification and dehumidification systems that can solve your humidity problems by removing or adding moisture to the air.

Heat and Energy Recovery Ventilators

Heat recovery ventilators and energy recovery ventilators increase the amount of fresh air in your home, keep air circulating, eliminate stale air, and prevent contaminants from the outdoor air from entering, all without impacting the temperature of your home.

HRVs get rid of stale air from inside and bring in fresh air from outside, but while they do this, they also exchange heat. This way, the temperature of your home stays the same without any additional burden on your furnace or air conditioner. ERVs function the same way, but they exchange both heat and moisture from the air.

HRVs are great for ventilating your home in winter if you live in a cold climate, while ERVs are ideal if you live in a milder climate with more humid winters.

Lennox FAQs

Why are Lennox furnaces so expensive?

There are a couple explanations for why Lennox furnaces are so much more expensive than a lot of competitors, and the first is brand recognition. Lennox pays a lot for marketing and advertising to ensure that their name is well-known, and this costs a lot of money.

Another reason is they put a lot of time and money into perfecting their products so that they can offer things like having the quietest, most efficient, and lowest emissions furnaces on the market.

How long will a Lennox furnace last?

With the right care and maintenance, a new furnace can be expected to last between 15 and 20 years on average.

That’s not to say a furnace won’t last longer, especially if you take good care of it.

If you want a good indicator of how long a furnace will truly last, then look at the warranty. Lennox warranties most of their furnaces—or at least the most important component—for the lifetime of the unit, meaning you can reasonably expect at least 20 years of reliable service.

Is a Lennox furnace worth it?

Lennox furnaces are reliable, durable, and highly efficient and quiet. However, whether their furnaces are worth the cost depends largely on your individual budget, needs, and expectations.

If you want the best warranty and cool features, then a Lennox might not provide you with enough value. If your major concern is efficiency, then there are other brands that make efficient furnaces that come close to rivalling Lennox.

On the other hand, if you're looking for reliability, dependability, quiet operation, a brand name, and a prestigious reputation, then Lennox could be what you're looking for.

Remember too that Lennox’s most expensive furnace is also the most efficient one on the market, so it will also save you the most in the long-term on heating bills. It will also likely qualify for rebates, and this could make it more affordable and more worth the price.
