Lennox offers some decent warranties that are in line with industry averages. They do exceed industry averages on the heat exchanger warranties on select systems. We recommend an extended labor warranty if available.
You will want a labor warranty especially if you purchase the premium models. Premium models have complex components and operating sequences. It will be necessary to hire a skilled technician to troubleshoot the problem.
Always read and understand the warranty before making the purchase. Many people don’t read it and are surprised later. The most common surprise is that you have to pay for labor. This is partially why we recommend the labor warranty if one is available. Lastly, don’t forget to register the warranty soon after installation is complete. Failure to do so may void any warranty.

Air Source Heat Pump Tips | Dual Fuel Heating
A dual fuel heat pump is a heat pump with a gas furnace for backup heating rather than electric heat strips.
Air source heat pumps have a backup heating source. In most installations, the backup heating source is electric heat strips. Electric heat strips are very cheap to install in most cases. However, while electricity is generally regarded as 100% efficient, producing it is more costly than other heating methods. For a more efficient heat pump, consider a dual fuel heat pump, or a heat pump with a gas furnace for the backup heat source. It will be more costly to install, but your monthly bills will be reduced.
Are Lennox Gas Furnaces any good?
In my opinion, Lennox makes a good furnace. The engineering is sound and they are innovative with efficiency and design in their gas furnaces. Additionally, quality control is excellent with Lennox. They also have a well-trained dealer network that is designed to benefit Lennox customers with factory-trained technicians. That is key in many areas of customer satisfaction.
It doesn’t matter what brand of furnace you purchase if it is installed incorrectly the furnace will not run well, experience constant breakdowns, never achieve rated efficiency, and will have to be replaced sooner. Go with a reliable, quality contractor over any brand. To Lennoxes’ benefit, they do have well-trained technicians. How do I know? I worked for a Lennox dealer for several years.
How long will a Lennox furnace last?
Working for a Lennox dealer, I saw gas furnaces still in operation that had been installed for 20 years or longer. And the customers were very happy with their Lennox furnace. Of course, the furnace was installed correctly and had regular periodic maintenance done to it.
Most gas furnaces, if installed properly, will last 15 or more years. I once read an article stating the average HVAC system (air conditioning and heating) lasted 13 years. I agree with assessment. Any furnace will last more than 13 years with proper care and attention. That means regular furnace maintenance.
Lennox Gas Furnace Reviews - Consumer Ratings | About
Editors note - I used to work for a Lennox dealer and while Lennox can over-engineer things a bit they do stand behind their products as long as the consumer complies with the proper procedures when purchasing their products. That includes any registration deadlines with the initial paperwork and having an authorized HVAC contractor install the system.
Lennox started in 1895 with a riveted steel furnace and eventually began producing other home comfort products. They boast more than 60 home comfort products in the product line-up. They also produce light commercial products for businesses.
