Lennox makes ten gas furnaces in three series:

5 Lennox’s Exclusive Features

Modulating

This is the necessary function for highest efficient(97%-98%) gas furnaces. Modulating is the key to obtaining beyond 95% efficiency. We recommend this function for those of you who plan on living in your home for a long time in winter. For more details, you can read our previous article: Modulating Furnaces: Are They Worth the Money?

Duralok Plus Heat Exchanger

Heat exchanger is the most important component of any gas furnace. Lennox has installed a Duralok Plus heat exchanger that is made of ArmorTuf steel. The ArmorTuf steel is patented and offers energy efficiencies and reliability. You can find a lot of positive feedbacks for this heat exchanger online.

Most efficient gas furnace (SLP98V) 98.7 AFUE

The Lennox Signature Collection SLP98V gas furnace achieves a best-in-class 98.7% annualized fuel efficiency (AFUE); just 2.3% of the heat produced is lost with the combustion gas exhaust.

This Lennox gas furnace is built with primary and secondary heat exchangers and condensing technology to capture and transfer more heat than any other gas furnace available today. This superior efficiency level is also achieved in the SLP98V with a modulating gas valve that, like cruise control, runs at the optimal level needed to keep temperatures perfectly balanced without overheating. The variable-speed blower contributes to efficiency by effectively utilizing the heat produced and transferred, never blowing unheated air at the beginning or end of the cycle.

SureLight Ignitor

This is another feature that makes the unit very reliable and durable. Lennox claims the Silicon nitride construction ensures the product lasts for years without regular breakdowns. This might be true, but almost all brands claim their units are reliable and strong.

SunSource solar modules

Imagine heating and cooling your home with a heat pump and having zero energy cost and using no fossil fuel! That’s possible with the Lennox SunSource solar home energy system. SunSource uses 3’x6’ solar modules to capture solar energy and deliver it to a Lennox heat pump or central AC equipped with solar-ready technology. Leftover energy can be used for your home’s electronics and small appliances. The Lennox SunSource system adds $8,000 to $20,000 to HVAC equipment costs depending on the number of panels used, but when savings are considered, it might be worth the investment if your home is in a sunny climate or if green heating and cooling is a top priority for you. Plus, the Residential Renewable Energy Tax Credit is still in effect. It allows you to take a 30 percent tax credit on the cost of a solar system. That’s one more reason to consider going solar!

Note for the short-term house:

Lennox is one of premium brands with higher initial cost. If you have the plan of moving house in less than 5 years, we recommend installing some quality but low-end level brands like Payne, Ruud or Armstrong. Looking for more budget brands? You can check our gas furnace brands guide.

Contractor Reviews For Lennox

Specific contractor reviews on gas furnaces are very rare due to the wide array of gas furnace models in the market. It is difficult to review all models on reliability and efficiency as most brands will work for years without a problem. BUT we just interviewed Kobie who is the after-sale manager who has 20+ years experience for Lennox, Goodman and Heil furnaces.

I have worked in the commercial and residential HVAC field for many years, and I know that a significant percentage of furnaces failures are as a result of poor installation and very cheap units. The Lennox Merit series has proven to be a piece built on high quality and reasonable price. I have installed this model for my cousin for eight years, and had any major failures. The Lennox gas furnace might not beat the Goodman, the Carrier or the Heil in the price but can do an excellent job of heating and cooling your home. Some consumers have reported the Lennox gas furnaces breaking down almost every year during the winter season. This might be true, but most breakdowns are associated with the poor installation of the units.

Note For Lennox Furnace Parts

It is worth noting that all Lennox’s parts are proprietary. The parts are three times as expensive as other parts which you can easily find in the market. So if you choose Lennox Furnace, we strongly recommend you purchase the extended warranty with the labor fee included.

$1,739 unit only SLP98V Vancouver B.C. 2500 sqft
I did a replacement of a twelve-year-old York gas Furnace with my Dave Lennox model. The old furnace had cracked the heat exchanger causing the unit numerous repairs at a very high cost. I did my research on Lennox and chose this model because of its high efficiency, and the price is manageable as well given the good performance. The furnace is quiet during operation not like the York that I had before which was too noisy. The unit has run without flaws so far for one year, and I have not done any repair or replacement, am happy with it. I would recommend this brand to any person who wants a top notch furnace at a manageable price
$1,899 unit only Signature SL280V Wilmington DE 1900 sqft
My son bought this Signature SL280V Lennox gas furnace about two years ago. It’s a heavy duty furnace and an energy star rated which makes it admirable. The disadvantage I see on this furnace is the much difficulty I had during the installation process. I was forced to deep my pockets and pay a technician to do the installation which was done perfectly well that I think it was somehow worth it. The warranty is impressive, and the heat exchangers are of high quality. The price is worth the results you get from the real performance of the unit. I am yet to have any problems with my unit, and I don’t hope for any problems soon. Lennox is the brand to choose.
$4,450 installed Elite G61 Canada 1600 sqft
As a contractor, I have worked with Lennox for quite a long time. Personally, I have installed two units of this brand for myself and tens of customers in different places. I sell Lennox furnaces because they are durable and rarely break. As long as the installation was performed well, then your furnace will operate and serve you for long without needing repairs and replacements. The price is just fine, be considering the high efficiency of this unit. I would recommend this to many of my customers and anyone else who needs a gas furnace that will last long and give you value for your money.
$3,990 installed Elite G60 New York 2400 sqft
I bought Dave Lennox Elite G60 series last year after my mum suggested that I try this brand. My unit runs perfectly from the first day and no repairs or replacements so far. The warranty is excellent. The furnace warms the house evenly, and my gas bill has gone down during the time I have had this furnace.
$4,230 installed Lennox Merit ML 195 Helena, Mt 2600 sqft
After numerous research for the best gas furnace regarding price and performance finally settled for this model. I met a contractor who took me through all the specifications of this model and then installed the unit for me. My experience with Lennox has been great, and I would buy this brand again and again. I have had my f for five years now, and no single repair plus the unit runs quietly that you cannot notice whether it’s functioning or not. You know what he was right; I haven’t had a problem with mine for years.
$5,300 installed Merit ML180 Port Williams Canada 2800 sqft
 Installed in 2014 and the price is a little high compared to your website price list. So far the performance is fine.
