GUIV Air Command - 80% AFUE

The GUIV Air Command 2-stage, variable-speed gas furnace provides exceptional indoor comfort. With its 2-stage, gas valve, super-efficient, variable-speed circulator blower and extra-tough silicon nitride ignition system, the GUIV provides uniform, comfortable temperature from room-to-room and floor-to-ceiling. The GUIV runs longer at a reduced speed so air is circulated in your home quietly and constantly, allowing air filters to remove more impurities. Our quietest furnace delivers money-saving efficiencies up to 80% AFUE. The stainless steel heat exchanger comes with a lifetime limited warranty.
