Rated 4.8 out of 5 by 104 reviewers.
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 Great product, very quiet! Great product, very quiet. Am impressed by the size and quality. October 16, 2014
Rated 5 out of 5 by Fantastic Furnace We have recently purchased and had installed a Lennox SL280UHV gas furnace and related air conditioner. We find it to be quiet, efficient and the perfect fit for our needs. I would recommend this furnace to any of my friends who need a new one. October 9, 2014
Rated 4 out of 5 by appreciate the variable speed feature Too early to tell if my gas bills go down. very much appreciate the quietness. I think my house is more evenly heated too. Very happy to have this new furnace October 8, 2014
Rated 5 out of 5 by SL280V Series Considering that my previous Lennox furnace was just over 25 years old, the upgrade to the SL280V is nothing short of amazing. Quiet, efficient (electric bill history verifies this), and a much smaller footprint. I've been running this unit for just about 8 months and continue to be happy & impressed. September 29, 2014
Rated 5 out of 5 by Runs very effectively The variable speed unit helps to keep it from running so often, and even when it does run, it is hardly heard in the house. Being compatible with the IComfort makes it very nice. August 20, 2014
Rated 5 out of 5 by Looking forward to winter I have not had an opportunity to use the furnace, other than with the AC unit. August 11, 2014
Rated 4 out of 5 by Quiet and Efficient This equipment is quiet while operating. The unit provides a low speed continuous fan option which keeps the entire house comfortable. Without this, the upstairs would not be comfortable. August 1, 2014
