"Excellent quality and productivity"
We have personally owned the furnace for 6+ years, but it looks to be the original furnace from when the house was built back in 1964. I love that it is still working, for one thing! I also love that we haven't had to do any kind of service or repairs to it in the 6+ years that we have lived here. I can't think of anything that I don't like about it. The only thing we have had to do is re-light the pilot light a couple times, which is no big deal. When we move, or when this furnace finally goes out, I will absolutely be looking to install a Lennox furnace. Although, if it goes out, I would try to repair it before I tried to replace it! I am sure that they built them better back in the day, and that is part of why it is still going, but I am willing to give Lennox the benefit of the doubt and buy their furnace again. I would completely recommend this furnace to anyone.

I am a retired HVAC tech and had this unit installed in a remodel of the home I bought. I knew the HVAC company and told them they had free reins but I also told them I was a retired HVAC service tech and I will be watching. The only problem I have found with the unit is the noise, I had told the installers I have isolation pads to put the unit on as it was being put in a closet that was being built and tiled on the floor. I will have to find a way to put them under the unit to make it quiet. Other than that I have owned this unit since 2009 and it has given me no problems. The one thing people need to realize is that if a unit us installed wrong in any way it will give you problems, some to no end, so I would really pay attention to the installers. Also, watch them. If you want, ask questions, and if they do not like you watching and asking questions throw them out of your home. These are the ones that need to be watched, in my opinion. Also just a few tips: try and get a high and low return so the high will be open for the summer and the low during the winter, have the duct work wrapped with insulation and try not to get the insulation they put inside that effects the air flow. Also, if they are doing a complete install (duct work and all) ask them to make the duct as square as possible or use round; you get better airflow.

This furnace is 21 years old and has been almost perfect. The drain tube plugged one time, easy fix. Honestly, I grew up in a home with Lennox and this one has been just as reliable. I change the filter but only have it cleaned professionally every two or three years.

"Do not buy this crap!"
This unit was installed in August 2006 as part of a remodel. It was not used until 2008 when house was occupied - part-time. I have only been in this house full time since June 2010 and have already had two service calls due to improper draining. Now I'm told the heat exchanger is leaking, which I found because it leaked into the crawl space. This is being used in a moderate California location! What in the world would it have done in a real cold climate?? The service company says labor is not covered on the 20-year heat exchange warranty (which is taking time for "approval") so it will cost me over $2000 to fix a 6 year old heater! What quality specs were they building to? I would not advise anyone to buy Lennox. I am deeply disappointed and wondering if I should just have the entire unit replaced but it cost over $7000 to install to begin with. I am told this has happened to other units in less than 10 years. Like I said, please stay away from this Lennox crap!

"Has to service every single winter"
I own five properties that I rent. The one with the Lennox furnace has the newest furnace of them all. Every single winter, the thing won't start. It is always something. Last time we were told that some kind of sensor was dirty. They gave us a list of things that could have caused it to go bad. The list included everything from regular dust, to perfume!. Perfume? Really? Come on! I can't believe these furnaces are so wimpy that even the smell of perfume could cause sensors to quit working. In the mean time, the furnaces in my other properties (which are not Lennox) have been working for over 10 years, with only occasional maintenance and a yearly inspection. I'm glad I didn't chose a Lennox for my cabin up north. I would probably be facing thousands of dollars worth of frozen pipes repairs. The only ones happy with my Lennox are the people who work at the company that has to service it. My Lennox is a billing machine for them.

"This is a review of the quality of my furnace and my satifaction."
This is the best furnace that I have ever owned because it is self cleaning and it comes with a lifetime warranty. I have also recommended this product to all of my neighbors and for my family and friends. The fact that I only need to change the filter twice per year also saves me a lot of money per year. In the future I will be recommending the Lennox furnace and air conditioning system for myself and all of the other people that I recommended it to in the past.

"Residencial Furnace Review for Fuel Oil Burners"
We own a very old and drafty home, with many large rooms. Previous owners could not afford to heat it and we struggled until we replaced our old furnace with a Lennox. We immediately saw a difference in the amount of oil we used through out the cold Northeastern winter months. Unfortunately, we had a very bad flood and lost it, but we didn't hesitate for replace it with another Lennox. This time, we got a more efficient model, and couldn't be happier. Our new Lennox is clean and quiet. The filter system keeps the dust down and the humidifier that is attached to the side, keeps us comfortable all winter long, and cuts down on static. Maintenance is easy. we have the Lennox dealer come and replace all the filters and maintain it, each fall, even though we could do this ourselves. I would recommend this brand to anyone. We have owned it for 3 years now, and haven't had a problem. WE could really use a furnace with more BTUs since in sub zero weather, it does have trouble keeping up, but that is really our fault for not picking a larger model. All in all, there really isn't much we don't like about it.

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.
