Replaced a perfectly good 25 year old furnace for this "high efficient" model. Has cost more in service calls than I probably will save in gas bills for the rest of my life! After barely a year, furnace kept cutting out (-40 outside) service man replaced flame sensor, had the furnace fully serviced last June and now is cutting out when goes to high output setting, LED's show no problem, another call. Replaced another furnace on rental, at same time has also needed at least 3 service calls and annual tuneup!

"Contractor vs Equipment"
Engineer for a mechanical contractor in NM. I felt compelled to comment on some of the reviews I have read here. In most of the reviews, if you read between the lines, poor workmanship and installation practices cause a lot of problems with all brands of equipment today. Noisy systems (ductwork), ignition problems (gas pressure and venting), frozen condensate lines (draining outside in cold climates), circuit boards (faulty wiring installations) are typical issues in the trade today. The contractor you chose is most important followed by the equipment. If the price is your first concern, you will probably be writing a bad review here also! Find a knowledgable contractor to install a quality brand (Lennox) and the cost will be reasonable.

"G32Q Problem Child"
Lasted for most of four years when the combustion air fan died to the tune of $300. Then it just stopped all together one day, indicating a flame rollout had occurred. The vents were clear, clean and properly installed. The fresh air intake fitting was melted, and if melted through, would have killed us with co. Luckily I had a good co detector! In my opinion, a very poorly designed system. Most other brands will shut down immediately on a flame rollout, a required safety measure. This piece of crap was melting the vent way before it indicated any problems.

We are an HVAC company. We try a lot of brands, like Goodman, Carrier, Bryant, Luxaire and Trane. You have to have a good installation company to install any of the products. Also, you need a manufacture who will stand behind their products. We try a lot of products and we found Lennox is the only one that give us the best service when we have a problem we can't fix. We call some of them and they never call us back and we look bad for our company. We talk to the Lennox service tech and he came out and fixed the problem for us. Also, I have a problem with one of the outdoor unit. We called our saleman and told him about it. He has no problem. He gave my customer a new outdoor unit. We replaced it for no cost to my customer. All manufacturers are going to have some problem with some of their units. Just make sure they will stand by their product. Lennox has a good housekeeping seal that nobody else has. If the company you are using can't do that, you have to find a company that will stand behind what they sell.

"G23 nothing but problems from day one"
I have hated this furnace since day one. Many problems including replacing a $200+ control/spark box. Waking up to a cold house numerous times in the am, reset power, and would work again for a day, a week or a month then fail again. Now, my heat exchanger has failed, and yes it's under warranty for 20 years, BUT FOR PARTS ONLY. Cheapest contractor wants $400-$600 dollars to replace. So heads up heat exchanger warranties don't mean anything!!!! Most are parts only!!! Check your paperwork. Also keep in mind if you want to fix your own furnace, Lennox will not sell you the part direct, you must have one of their techs do the work. This stinks if you are handy, and want to save some money doing the work yourself! Stay away from Lennox!

"Lennox - a breath of fresh quality!"
Had a Bryant high-efficiency furnace that experience several failures and finally a secondary heat exchanger that went bad. Rather than accept a small manufacturer discount for replacing, we switched to a Lennox two-stage variable high-efficiency. What a world of difference! Quieter, no repairs to date, easier to maintain. Per discussions with various techs, Lennox incorporate many small differences that combine to deliver a superior product overall. After three years, we can say with confidence that this unit is far superior. Some friends just had a Lennox installed and are equally happy.

"My Lennox is the best ever made"
31 year old Lennox (November 1979) gas furnace 100,000 btu, serviced every year, no repairs of any kind. Just this year, they cleaned the burners for the first time. No cracked heat exchanger etc. The blower motor is also used a lot for AC. I can't believe it is still working so well. Quiet as a mouse. It seems they don't make them like they used to. I bet most of the parts are Chinese now. Based on what people are saying, I fear having to buy a new furnace.

"Lennox Pulse furnace (G14)"
This unit is an 80k btu unit installed in a 2000 sq.ft., 150 year-old, home in 1987. The previous owner replaced the control board in the mid 90's, and just recently the exhaust trap became fouled. A relatively minor repair. This unit has been so reliable and efficient that I am hesitant to replace it. I can't see a large capital expenditure for such a small increase in efficiency. The only minor complaint is the noise that the old pulse furnaces make. All the same, I hope to repair it until it is absolutely shot, at which time I will replace it with a two-stage unit. We added a Bryant AC unit a few years ago and the system seems well sized and was well installed as it runs and works very well together.

When I built my home in 2003, the cost of natural gas was skyrocketing. I thought I'd save some heating cost by installing a Lennox 90ufg a3 75-6 high efficiency furnace that the builder recommended. The cost to upgrade at the time was an additional $1200. Big mistake. In 2008, I spent $512.86 on a new inducer motor because the bearings were bad. This morning the service tech said the ignitor and its circuit board had to be replaced at an estimated $555. I politely asked the tech to leave and called a reputable HVAC contractor to replace the furnace. Do the math. Almost $1100 in repairs on a furnace that was built in 2002. No thanks, Lennox. I wouldn't recommed Lennox to anyone. The old 85% efficient Bryant furnace I had for over 25 years never had a repair bill like this. Someone at Lennox better rethink their approach to the market. The future looks grim for them in my eyes.

"Lennox G26 High Efficient Furnace"
This furnace replaced our old g-14 Pulse on warranty. We were given the option back then at the time (due to the lifetime Limited Warranty), to either replace the heat exchanger or get a whole new furnace. The g-14 we had lasted a good 25 years. This one, we have now is at least 10 years now and there was not one single malfunction with it yet. We replaced our A/c unit about 6 years ago. The old one lasted 30 years (it had r12 refrigerant). As posted above, the unit is only as good as whoever installed it and whether they had adequate training or knowledge at the time. I'm very pleased with Lennox. It is one of the superior brands out there. They own Armstrong, Ducane and Air-flow. I would also like to point out that they are no way as bad as Olsen or Carrier, which are the lower brands in the scale. Now in Canada, the only furnace you can buy by law has to be 90% or higher efficiency. I hear Lennox is working on producing a new 98% efficient furnace. Hopefully, they can take the knowledge from the old G-14 and put it to good use. Currently their newer furnaces, G51, G61, G 61MPV, G71MPV are one of the quietest and most efficient furnaces in the market.
