Consistent Temperatures

A variable-speed blower motor allows for constant and efficient adjustments of air flow speed and gently disperses even heat throughout your home. It also prevents loud blasts of air that can occur when a single-speed system starts up, providing quiet operation for enhanced comfort.


Energy Efficiency that Adapts to Your Needs

An energy rating of up to 97.5% AFUE means the SL297NV can potentially save you hundreds of dollars per year, compared to an older furnace.

The variable-speed motor maintains a consistent temperature in your home using as little fuel as possible. This helps you stay comfortable and reduces your utility costs.


Everything Comes Together Perfectly

Together with other products from the Dave Lennox Signature® Collection, the SL297NV takes comfort to an entirely new place.
