Comfort™ 92 Gas Furnace (FER)

  • California Prop 65

The 59SC2D Multipoise Comfort™ Condensing Gas Furnace features SEER-boosting year-round electrical efficiency when paired with a compatible condensing unit. Energy efficiency is at the heart of this furnace with up to 92.1% AFUE gas efficiency and the electrically-efficient basic fixed-speeds, constant torque (FCT) ECM blower motor. This gas furnace also features 4-way multipoise installation flexibility, and is available in nine model sizes. The 59SC2D can be vented for direct vent/two-pipe, ventilated combustion air, or single-pipe applications. Units are design certified in Canada, and are certified for mobile/manufactured home use.
