Goodman ad9s800603ax 80 Afue Downflow Gas Furnace 60K

Product Description

The GOODMAN ad9s800603ax is a single-stage, multi-speed ECM downflow and horizontal gas furnace rated at 80 AFUE. It delivers 60,000 BTU/h high-fire input capacity with a high-fire output of 48,000 BTU/h, making it suitable for residential and light-commercial ducted heating applications. The unit operates on a single-phase, 115-volt, 60 Hz AC circuit and features a Low NOx burner configuration that meets California emissions requirements. Licensed HVAC technicians handle procurement, installation, and commissioning of this unit class.

This furnace is configured for downflow and horizontal installation, fitting applications where supply air exits through the bottom or is routed horizontally into ductwork. With a nominal cooling coil capacity of 36,000 BTU/h (3 tons), it is sized to pair with a matched 3-ton cooling system in a split configuration. The 14-inch unit width and 33-3/8-inch height make it compatible with standard closet and alcove installations common in California and other Low NOx regulated markets. The multi-speed blower motor provides airflow up to 1,035 cubic feet per minute on high in heating mode.
