Lennox Warranties
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.

Lennox Gas Furnace Reviews & Ratings
So it’s time to buy a new furnace and air conditioner. Where do you start? How do you protect yourself and get the best deal and installation of the new system? The new installation will require the services of an HVAC contractor. How do you find the best contractor?

- What’s the most important decision factor when buying new HVAC equipment? A) Brand or B) Quality of contractor. If you answered B give yourself a gold star.

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.

Our old furnace went out and was deemed unsafe by the repair guy. We scrambled to get a new because it was cold middle of February and I have 3 kids. Made a few phone calls and finally got the number for someone I was told I could trust. The next day they came by and gave me a quote and I said let’s do it. Later in the day they came buy and brought some space heaters to keep the house warm because they said it might be a few days before they could get the furnace we needed. Within 2 days we had a new furnace. It was a mid efficiency Lennox and for the last 2 years it has kept our house nice and toasty even on the coldest days. Haven’t had any issues. We keep it serviced. The guy comes every fall and checks everything out. So far so good.

Lennox heating unit purchased in 2006 is TERRIBLE,
Our Lennox was purchased to replace an old unit in 2006. The motor failed one DAY before the 3 year warrenty expired and it cost us $400 to replace, for the labor. THIS is outragous! Now the control board has failed, we are forced to hire another repair person, and this has caused our air-conditioning unit to not work until the faulty control board is fixed. WE will never purchase or recommend Lennox to anoone again. We have no idea what our final cost to fix a 2006 unit, which should have been good for at least 20 years will cost. WE will file complaints with Lennox. Meantime we are hot, ill and VERY unhappy with this company. Wish we had found the rating of 3 for reliability and installation before our purchase. Please don’t make the same mistake we made. I got the name of the company from a neighbor who works with Lennox and I’m really sorry I ever trusted this company.

Disappointed with Lennox furnace
I bought a Lennox mmodel CR 26-41-1, and have had nothing but problems from the beginning.
After doing some research, I find that many consumers are experiencing the same problem I have: The furnace fails to ignite properly.
After having my furnace looked at several times, servicemen say they find no problem. I have replaced 4 thermostats, thinking it was a thermostat problem.
After doing my research, it is apparent to me that Lennox furnaces have some type of defect with the ignition mechanism.
I WILL NEVER BUY ANOTHER LENNOX!

DO NOT PURCHASE LENNOX SERIES
We had moved into our house with Lennox Merit series unit in 2002,Model C26-41-1 the very next year 2003, needed to install hard start booster kit (cost $328.00);
By 2004, the contactor was burnt out, replacement $210.00; Then by 2006, A/C was not working properly, technician came and said we didn’t need the capacitor, so he took it out for some reason, service cost $150.00; The next year in 2007, A/C again wasn’t kicking on properly in the Summer, this time had the conducer motor replaced, total repairs $576.00; On to 2009 Summer, found out there was a capacitor that was in there after all and needed to be replaced, cost $211.00. So far all above was part of the A/C. Then this week, Fall 2009, the furnace motor and blower started to make loud noise, repair estimate: $1146.00. The funny thing is the repair guy said we’ll be better off replacing the entire furnace at this point because it will start to go after a little while. I told him we have had a bad taste for Lennox by now. Thanks, but no thanks!

I purchased the signature series g71p in march of this year (09). The furnace is everything it says it is. This model is very efficient and the company that installed it were great. They took the time to do a j-load calculation which shows me they truly install what you need in your square footage. I have no complaints on this model, it is very quiet as well.

I too was impressed with the favorable reviews posted about the G61MPV prior to my purchase in 2006. However, reality has been a harsh teacher. Have had nothing but problems with this unit since year 2, with a majority of the problems being a due to flame sensor issues, nut have also included almost every part in the box from the circuit board to the collector box collecting a thick gunk. The flame sensor needs to be cleaned at least twice a season even after being replaced. Now I have a problem with corrosion/oxidation on the burner assembly which will need to be replaced. Luckily I have the ten year warranty which provides a sense of relief for coverage and repairs, but that too is going to run out in the very near future, While the service company has been good in responding to my issues, the problems still exist with no clear resolution in sight. Would I ever buy another Lennox product – not a chance. One would think that with all the issues that have been cited with these furnaces, there would be some type of recall program and resolution provided by Lennox if they were truly interested in their brand name.
