Lennox Elite furnaces are a series of gas and oil furnaces currently in production. Five gas models are available, ranging from two high-efficiency models, the EL296V and the EL296E, with an AFUE rating of ninety-six to the EL280, which has an AFUE of eighty. The EL296V and the EL296E are both Energy Star-certified. Single-stage and two-stage heating models are available in the Elite series. One model, the ELO183, is listed as an oil furnace in the Elite series, with an AFUE of eighty-three.
Bought two Carrier 58ss furnaces, along with two Carrier ACs, and two Carrier Electronic filters in 1982. Had trouble from the beginning with the furnaces and air cleaners. Furnaces had to have circuit boards repaired, replaced numerous times, as well as fan motors replaced, etc. ACs were another story… rock solid, and we have summers with over 100 degrees for weeks at a time here in the midwest. 27 years on the ACs until one died this month. Not bad! The furnaces are another story… Finally replaced the Carrier furnaces with Lennox G50s in 2004 when one of the Carriers died for the last time. Had one service call on one of the Lennox furnaces in the interim and that was such a simple fix that the service tech incorporated it into a seasonal tuneup charge. Nice! Short story, Long… Carrier: good ACs, poor furnaces. Lennox: good furnaces… do I dare replace the ACs with another Carrier product or take a chance on Lennox ACs/Heat Pumps?
"Angry and disatisfied"
We bought a Lennox Elite Series 11 yrs. ago we have replaced the ciruit board twice now, the ignition switch once, and had the fan repaired, I even have had a certified contractor come and just clean and oil it because I am so afraid of freezing another winter. It is so noisy when it is running it sounds like a jet plane taking off. It is a piece of crap I will never purchase another Lennox and do not recomend it to anyone. I agree with the person who commented about Lennox should stand behind their product and give some compensation back in return. Next repair it is gone.

I had a Lennox g60dxv installed in March of 2005. I had contracted for the smallest unit (70,000btu) but they installed the next size larger, When I questioned the salesman he said he substituted the larger unit so it would never go into the second stage. hah! I think it was because the larger cabinet fit my installation easier. I made them remove the oversized unit and replace it with the proper sized unit. I had the free service after the first year and was less-than-impressed by the technician. He was certainly likeable and seemed to know what he was doing but I had to ask him to check the gas pressures and then fix the battery clip on his manometer. He did not clean the heat exchanger, which Lennox suggests be done at annual check. About a month into the next heating system the unit failed without any diagnostic lights pointing to the problem. I found the draft switch connection plugged with corrosion and upon cleaning it worked okay. This same thing happened again a couple of weeks later but since the second cleaning it has been working fine the rest of the season. The installing company has been in business since 1922 so mere longevity in business is no guarantee of either quality installation or service.
An HVAC installer writes on the hvacsite.com forum about a problem with his personal Lennox Elite furnace. He is having trouble with the fan turning on and off properly; the experts at the forum agree that the problem is probably a faulty electrical board.
Another post on hvac-talk.com points out the fact that most HVAC forums highly recommend Lennox and Carrier products. Installers often say a homeowner cannot go wrong with these companies, and they should compare warranties, rebates, and tax credits to make a decision.
A writer on diychatroom.com has inherited a Lennox Elite furnace with the purchase of an existing home. He does not believe it has been serviced, and he is having problems with fan noise and the thermostat. The contractors online direct the homeowner to clean several parts on the furnace, and then see what happens. The post makes a good point about regular service check-ups.
