SL280V Variable Speed Gas Furnace
The Lennox SL280V is a variable-speed, two-stage gas furnace. It is the quietest furnace in its class and the variable-speed blower maintains comfort with an adjustable flow of air, preventing temperature swings and blasts of air when your system starts. An energy rating of 80% AFUE means the SL280V can significantly reduce your heating costs, compared to an older furnace. Because it’s designed with SilentComfort™ technology, the SL280V operates with very low noise levels – up to 4.5x quieter than competitor models! 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.
