2 Ton Goodman 15.2 SEER2 R-32 Horizontal Heat Pump Package Unit, GPHH52431
The Goodman GPHH52431 is a 2 ton packaged heat pump that houses the scroll compressor, outdoor coil, indoor evaporator coil and ECM blower in a single weatherproof cabinet. As the entry size of Goodman's GPHH5 15.2 SEER2 series, it delivers 23,600 BTU/h of total cooling and 24,000 BTU/h of heat pump heating at 47°F using R-32 refrigerant, with horizontal supply and return connections for slab or rooftop installation. It is a practical choice for homeowners, contractors and property managers who need all-in-one heating and cooling for a smaller home, addition or office without giving up indoor closet or attic space.
Is a 2 Ton Heat Pump Package Unit the Right Size?
A 2 ton package unit is designed for spaces whose calculated cooling load lands near 24,000 BTU/h. With about 875 CFM of nominal indoor airflow, the GPHH52431 commonly serves smaller single-story homes, condos and villas with outdoor pad or roof access, room additions, and compact offices. The load calculation should drive the choice, not square footage alone.
Insulation levels, window area and orientation, local design temperatures, duct leakage and occupancy all shift the load. Heating output also falls as outdoor temperature drops, from 24,000 BTU/h at 47°F to 13,000 BTU/h at 17°F, so many installs add a field-installed electric heat kit for backup. Our AC tonnage and BTU calculator is a good first step before you finalize the size.
Ideal for: Smaller homes, condos, additions, modular offices and light-commercial suites that need complete heating and cooling from one outdoor cabinet.
Need more capacity? Step up to the 2.5 Ton Goodman GPHH53031 Packaged Heat Pump for spaces with slightly higher cooling loads that still fit the small-chassis footprint.
Recommended applications are general guidelines only. Actual system requirements depend on a load calculation, insulation, ductwork, climate, occupancy, and local code requirements. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

Because the GPHH52431 ships fully charged with R-32 and carries both coils and the blower in one small-chassis cabinet, installation comes down to setting the unit, connecting ductwork, power and thermostat wiring, and starting it up. There is no line set to run and no separate air handler to find room for. Indoor metering uses a TXV, and the 1/2 HP ECM blower offers five speed taps to match airflow to your ductwork.

Frequently Asked Questions
What size home is the GPHH52431 2 ton package heat pump designed for?
The GPHH52431 fits homes and spaces with a calculated cooling load near 24,000 BTU/h, which often means smaller single-story homes, condos, additions and compact offices. A Manual J load calculation is the best way to confirm the right size.
Which electric heat kits fit the GPHH52431?
This page offers 5 kW, 8 kW and 10 kW breakered heat strips (HKP-05C/HKTPD051, HKP-08C/HKTPD081, HKP-10C/HKTPD101) for field installation. You can also browse Goodman heat strips.
Does the GPHH52431 use a single-stage or two-stage compressor?
The 2 ton GPHH52431 uses a single-stage scroll compressor. In the GPHH5 series, two-stage scroll compressors start at the 3 ton GPHH53631.
What breaker size does the GPHH52431 need?
Without a heat kit, Goodman lists a minimum circuit ampacity of 18.03 and a maximum overcurrent protection of 25 amps at 208-230V single phase. Use time-delay fuses or HACR-type breakers, size wire per the NEC, and always confirm against the unit's rating plate.
Can the GPHH52431 replace an older R-410A package unit?
Yes, as a complete unit replacement. The GPHH52431 is self-contained and factory charged with R-32, so no refrigerant from the old system is reused. Check that your duct transitions match the 14" x 14" supply and 14" x 22" return openings. A square-to-round adapter (SQRPCH101) is available.
What properties commonly use a 2 ton packaged heat pump?
Typical installs include starter homes, condos and villas with an outdoor pad, garage or bonus-room additions, small professional offices, and rental properties where the owner wants all mechanical equipment outside the living space.
