Rated 5 out of 5 by This made such a difference My house after upgrading to Lenox is now more evenly heated in a much shorter run time. Amazing and toasty warm (even in southern california). November 30, 2012
Rated 5 out of 5 by So quiet Very quiet and efficient. Can barely hear it running. House stays evenly warm. July 28, 2014
Rated 5 out of 5 by So quiet! We recently had to replace our AC unit and did a package with the SL280V. When the old unit would come on, we'd have to bump the TV volume up a few notches to hear it over the noise of the blower. But this new unit is quiet...about like the noise from a refrigerator running. So nice! July 25, 2014

Rated 5 out of 5 by Great furnace! Excellent, I had a 12 year old furnace eating my gas bill and ran all the time. This Lennox is superior compared to what I had. The continuos fan keeps my house warm. Very comfortable and has a great output. Most important, it doesn't run continuous, it keeps my 2500 home warm! January 19, 2014

Rated 5 out of 5 by Great product and service. Great buy. We used to have to keep the old thermos at 72 to maintain sufficient heat. With the new unit, 67 degrees keeps it warm. We really like the cycle two concept. We're glad we called J.D.Vigil November 1, 2013
