Goodman gphh54231 Packaged Heat Pump 3.5 Ton 15.2 SEER2

Product Description

The Goodman gphh54231 is a 3.5-ton packaged heat pump designed for horizontal installation in residential and light-commercial forced-air systems. It delivers 42,000 BTU/h of cooling capacity and 41,500 BTU/h of heating capacity, operating at a 15.2 SEER2 efficiency rating. The unit runs on 208/230-volt single-phase power and uses R-32 refrigerant, an A2L-classified refrigerant with a lower global warming potential than legacy refrigerants. Licensed HVAC contractors install and commission this equipment. It is not approved for sale in California.

The gphh54231 is built for horizontal-configuration installations, making it well suited for applications where vertical clearance is limited, such as crawl spaces, closet platforms, or low-profile utility areas. It fits into new construction and replacement projects that require a self-contained heating and cooling solution in a single cabinet. The unit integrates the air handler and outdoor refrigerant circuit in one package, reducing field refrigerant line work compared to split systems. This product is sold to licensed contractors only and is available in select geographic areas.

• 208/230-volt single-phase electrical supply

Compatibility

Designed as an OEM packaged heat pump unit for horizontal-configuration residential and light-commercial forced-air applications requiring 3.5-ton capacity at 208/230-volt single-phase power. Sold to licensed contractors only in select service areas.

Installation Notes

Installation must be performed by a licensed HVAC contractor holding the appropriate refrigerant-handling certification, as R-32 is an A2L mildly flammable refrigerant requiring adherence to current ASHRAE 15 and local mechanical code requirements. Disconnect and lock out all electrical power before servicing the unit. Verify that the supply circuit matches the unit voltage and ampacity rating before connecting. Confirm horizontal mounting clearances and condensate drainage paths meet manufacturer and local code requirements before commissioning.
