This furnace has been very reliable, with only one problem in 15 years. We had a clogged condensate drain & the furnace shut down, this was actually a maintenance issue. I notice that all brands have many negative reviews. Proper installation is the key to quiet, efficient & trouble free operation.

"I had a Lennox 3 ton unit in my home"
I had a Lennox 3 ton unit in my home, built in 1982. It had to have a new compressor, several sets of contactors on the outside AC unit, a new outdoor fan motor, a new indoor fan motor, and a new gas valve, all over a period of 20 years. The unit was serviced regularly by a Lennox contractor for the first 15 years. I did not see any benefit to paying their rate after so many failures, so I switched to an independent to service it for the next 5 years or so. Based on the repeated repairs of failing components, I decided to replace the unit when it needed a second indoor blower motor. Now on to the G24M I put in my current home 15+ years ago, installed by a Lennox dealer. This unit was a mid-efficiency unit when it was installed. It has an electronic ignition that was designed to save gas by eliminating the standing pilot light. I have replaced the control board three (3) times. The first time was about $600 from my Lennox dealer. The second time, it required conversion of the spark igniter to hot surface ignition, and was about $400 using an independent dealer. This third time I had an independent replace it for $200. Its a universal unit, as there is no direct replacement from White Rodgers. The universal unit does not have adjustable blower time after the gas shuts off and it's too short, so now the blower will re-cycle after the unit shuts down. I have also replaced the combustion blower ($$$), the indoor blower capacitor and several furnace limit switches. I have had issues with the vacuum line having water freeze in it between the combustion blower and the limit switch, rendering the unit inoperable. This was misdiagnosed by the Lennox dealer, and when I pointed it out after fixing it myself, no refund was offered for all the parts they replaced that were not needed. They even had the gall to tell me the unit was worn out and needed to be replaced. On the AC side, I have had a leak in the evaporator core for 10 years. Nobody wants to touch that repair. The outside contactors were replaced a couple of times, but I am told every time it is serviced it needs new contactors. The last couple of summers I have been told the Freon smells like acid, indicating the compressor is going out. I spent $5000 on this POS back in the late 90's. I could buy a lot of natural gas for the cost of all the repairs due to the fancy electronics. Crap, they are giving away gas here due to oversupply. And what is the environmental cost of making and disposing of all these electronic parts?

"Lennox furnaces are shit"
8 yrs and $2500.00 later, the computer board goes. Lennox says tough. A garbage company.

I've been a Lennox user for 30 years and when the flood hit my area last September, I had 6 feet of water in my basement which destroyed my furnace, hot water heater, and ac outside. I immediately called my awesome mechanic, Mike Culp, and within 2 weeks I had ac and furnace replaced. Lennox products and my mechanic will always be at the top of my list.

"Ducane a Cheaper Lennox"
I've had my Ducane furnace for fifteen years now, and it still works good. I've only had one repair on it in all that time. The fan ignition wire burnt out. It cost me $300 to get it replaced though, but that's not the furnaces fault. I had it cleaned twice by a great guy named Charlie Walsh who is very popular in my city Niagara Falls Ontario for doing a perfect job. He takes the whole thing apart and cleans every piece. It takes him two hours to complete the job. I also replace the filter every three months. So I do my part in making sure it runs smoothly.

"Did not last"
Maybe we have more luck than I thought. Replaced old electric system with Lennox heat/ air conditioning system. This required putting Gas in house and substantial plumbing. We took a ten year service contract on the unit. You can guess what happened at the beginning of the 12th heating season. Fife box imploded, furnace has to be replaced. Nothing wrong with compressor for the ac but they tell us that has to be replaced also, it's not compatible with any other system (or the new Lennox). I expected to get at least 30 years: got 11.

I am writing on behalf of my Lennox installer, Azzo Air located in Glenview, IL. Emmanuel Azzo is the owner and technician. He is "outstanding". He is concerned about his clients and their well being. Back in October when he was doing his semiannual service call, he discovered a co leak. Fortunately, we had not turned our heat on. If we did, I wouldn't be able to write this review. He informed me of a crack in the heater core and he was able to install our Lennox heating unit. Emmanuel is one super technician and I have referred plenty of times.

Purchased in 2003 with a heat pump (another nightmare) for just over $8000 including installation. To date: $4000.00 for a replacement heat pump. $1100.00 for "service" checks and hardware. $2800.00 for parts and labour "Over and Above" Looking forward to discussing this further with the installer/"service" provider in small claims court.

"DO NOT Recommend"
Wi-Fi icomfort thermostat that supports energy efficient AC and 2-stage furnace is defective. Just had system professionally installed in April 2013. 8 thermostats later installation it staff admits bugs in system. System gives erroneous indoor temperature readings, off by 3 degrees and system has failed. 1st time thermostat crashed and burned out, 32 degrees out, freezing inside house. If set indoor heat to 70 readings of 73 will appear on face of thermostat and furnace will not turn on. DO NOT WASTE YOUR money or time. $7,000 Lennox is badnews. Corporate Lennox non-responsive to my calls.

"Arm Strong Air Tech furnace"
The Armstrong Air Tech furnace develops exhaust leakages in about a year. Exhaust leakages from the front gaskets, exhaust fan axle opening too large, from interior heat exchanger seals. Do not buy this brand.
