PRODUCT INFO
3.5 Ton Cooling, 100,000 BTU Heating
The Goodman GPGM54210031 delivers 3.5 tons of electric air conditioning and 100,000 BTU of natural gas heating, providing reliable year-round comfort for your home. It comes factory-equipped with a natural gas valve, and a propane conversion kit is available separately for field installation if needed.
High Efficiency: 15.2 SEER2 AC, 80% AFUE Heating
The GPGM54210031 offers a 15.2 SEER2 air conditioning rating, which is considered highly efficient and about 12% more efficient than the 14 SEER2 national standard. On the heating side, the unit achieves 80% AFUE, meaning 80% of your heating gas expenditure goes directly toward warming your home, with the remaining 20% lost through normal venting. These efficiency ratings make the GPGM54210031 a versatile choice suitable for installation anywhere in the U.S.
Comprehensive Warranty
Goodman backs this unit with a 2-year replacement warranty, a 10-year parts warranty, and an impressive 20-year warranty on the heat exchanger. To maintain warranty coverage, the unit must be installed according to local and state codes and registered online with the manufacturer.
Durability and Reliability
Built with heavy-gauge steel and superior noise-reducing insulation, the GPGM54210031 is designed to last. When properly anchored, it meets Florida building code requirements for hurricane-resistant construction. For added reliability, the blower motor is fully sealed and permanently lubricated, the evaporator coil is all-aluminum, and the redundant gas valve features power-assisted combustion, ensuring your system operates efficiently whenever you need it.
Installation and Maintenance
The unit operates on natural gas out of the box, but a propane conversion kit is available for field installation. The GPGM54210031 is precharged with refrigerant, reducing installation time and materials costs. Its multi-positional design allows for flexible placement, whether on a roof or at ground level. Maintenance is made simple with two access panels, one on the top and one on the side, for easy service of key components.

Goodman prioritizes affordable comfort and efficiency. The GPGM54210031 combines quiet operation, self-contained design, and easy installation to provide a dependable, comfortable climate for your home.
