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.


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.


Everything comes together perfectly

Together with other products from the Dave Lennox Signature® Collection, the SL280V takes comfort to an entirely new place.

Efficiency Rating (AFUE) – 80

Warranty – 20-Year Limited Warranty on Heat Exchanger. 10-Year Limited Warranty on covered components.
