GUIS/GCIS Air Command - 80% AFUE

The GUIS Air Command 2-stage, multi-speed gas furnace delivers comfort, quiet and efficient reliability. With its 2-stage, gas valve, multi-speed circulator blower and extra-tough silicon nitride ignition system, the GUIS keeps your home at a more constant, comfortable temperature than single-stage units. The GUIS runs longer at a reduced speed so air is quietly circulated in your home, allowing air filters to remove more impurities. The GUIS delivers money-saving efficiencies up to 80% AFUE. The stainless steel heat exchanger comes with a lifetime limited warranty.
