SL280V
VARIABLE-SPEED, TWO-STAGE GAS FURNACE
The quietest furnace in its class*
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.
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.

Great heating performance that doesn’t drive up utility costs
Through its quiet and continual rotation, the Power Saver motor can deliver significant energy savings, compared to standard single-speed motors.
ML180
STANDARD-EFFICIENCY GAS FURNACE
