Variable speed keeps you constantly comfortable
Variable speed keeps you constantly comfortable
A
variable-speed blower maintains comfort with an adjustable flow of air,
preventing temperature swings and blasts of air when your system starts.
Efficiency you can feel good about
An energy rating of 80% AFUE means the SL280V can significantly reduce your heating costs, compared to an older furnace.
A more efficient home environment helps contribute to a better global environment.
Feel good this winter and all year long knowing you can save energy and money without compromising on comfort.
Best furnace I have ever had. It is super quiet.
Not a lot of sound, just a lot of perfect air
Because it’s designed with SilentComfort™ technology, the SL280V operates with very low noise levels.
Two-stage heating for always-on performance
While
most furnaces are either off or on, the SL280V can actually deliver two
different levels of heat based on how cold it is outside. This lets it fine-tune fuel use to carefully
match your comfort, keeping your home warm and energy-smart.
"The variable speed keeps the temperature very consistent throughout the house, and is much more quiet than I am used to. Gas and electric bills are down."
Everything comes together perfectly
Together with other products from the Dave Lennox Signature® Collection, the SL280V takes comfort to an entirely new place.

This made such a difference
December 01, 2012My house after upgrading to Lenox is now more evenly heated in a much shorter run time. Amazing and toasty warm (even in southern california).

Problematic Unit
July 17, 2022Installed this heater with outdoor ac unit el16xc1 in May 2021. Immediately disliked a whistle and jet like roar on low stage ac blower. Heater blower noise is ok. The inducer motor went this year. The ac unit had to be completely replaced a month ago due to sporadic loss of refrigerant (3 house calls needed to determine problem).
