The Goodman GPHM52431 is a compact, all-electric heat pump package unit. It heats and cools a small home from one outdoor cabinet, with no gas line or flue. It delivers 24,000 BTUh of total cooling at 14.4 SEER2, and 22,600 BTUh of heating at 47°F (3.60 COP) with a 6.7 HSPF2 rating. It is built with R-32 refrigerant, TXV metering on both coils, a 4-row evaporator coil, and a multi-speed ECM blower. Its louvered galvanized cabinet meets 2023 Florida Building Code hurricane requirements when anchored. Compare more heat pump package units.
Is a 2 Ton Heat Pump Package Unit the Right Size?
Size a heat pump to the cooling load first. The GPHM52431 fits homes with about 22,000 to 24,000 BTUh of summer heat gain, such as compact single-story homes, manufactured homes, and small offices. It moves 800 CFM nominal airflow through the duct system. Get a quick estimate with our AC tonnage calculator.
Heating output falls as outdoor temperatures drop: 22,600 BTUh at 47°F and 12,800 BTUh at 17°F. Below the balance point, a field-installed Goodman heat kit of 5, 8, or 10 kW supplies backup heat. Choosing the smallest kit that covers your coldest days keeps installation and operating costs down.
Ideal for: Small all-electric homes, manufactured homes, garage apartments, and small offices in mild to moderate winter climates.
