Rated 5 out of 5 by Super product! I'm really surprised at how fast it gets up to the temperature I set and it's very quiet which is a plus! September 19, 2014
Rated 5 out of 5 by Well built, attractive furnace! We had this unit installed recently (August 2014) as part of a furnace / AC replacement of a much older system. I'm impressed by the solid construction and it is somewhat quieter than our old furnace. September 12, 2014
Rated 5 out of 5 by Clean lines,quiet operation So far so good with the furnace, replaced a 28 year old furnace that sounded like a freight train when firing up. Have not had a need for the heating yet but when tested on install was really quiet and pushed lots of air throughout the house. August 6, 2014
Rated 4 out of 5 by 80% AFUE works for me While others go for the high-efficiency models (and get possible tax credits), I chose this model and I'm happy I did. I did not want the trouble and expense involved in installation as well as dealing with the condensate removal to the outside. So I have a furnace that is quiet, was easy to install, and will (I hope) save me on my heating bills compared to my old furnace. It's too early to tell at this point. My only complaint - and this applies to all newer furnaces, I understand - is that it requires a separate filter assembly. My old furnace had its own. July 6, 2014
Rated 5 out of 5 by Superior product through and through This whisper quiet heater is fabulous! You won't even know it is on. Heats my home quickly, quietly and the continuous fan circulation is a great idea, and keeps warm air circulating, making the heater kick in less, and that is a GOOD thing! Lennox is a superior quality product, a purchase you will be glad you made. April 7, 2014
