A step up from single-stage furnaces because its gas valve offers an additional lower setting. Most of the time the unit will meet heating needs at its lower stage, resulting in balanced and consistent temperatures with lower energy use. Should the low heat setting not heat the space quickly enough, the furnace will switch to the high setting. This ability to switch between the two settings offers greater comfort and efficiency.
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.
Not only is the SL28XCV air conditioner part of the Dave Lennox Signature® Collection, it’s part of the Ultimate Comfort System™, which combines the best of everything Lennox has to offer to create an unprecedented whole-home comfort system that seamlessly and intelligently works together to stay finely tuned to your home and deliver consistently clean, perfect air.
