2.5 Ton Goodman 15.2 SEER2 R-32 Two-Stage Heat Pump Package Unit GPHM53031
The Goodman GPHM53031 is the first two-stage size in the GPHM5 line. It is a 2.5 ton packaged heat pump that runs on low stage most of the year for quieter, steadier comfort, then ramps to full capacity on the hottest and coldest days. It delivers 29,600 BTUh of total cooling at 15.2 SEER2 and 28,600 BTUh of heating at 47°F, with a 6.7 HSPF2 rating. A 980 CFM ECM blower, factory-charged R-32, and heat kit options up to 15 kW make it an efficient all-electric choice for mid-size homes. See all heat pump package units with backup electric heat.
Is a 2.5 Ton Two-Stage Heat Pump Package Unit the Right Size?
A 2.5 ton heat pump fits cooling loads of about 27,000 to 30,000 BTUh, which is common for mid-size homes and double-wide manufactured homes. Compared with the 2 ton GPHM5, it adds 5,600 BTUh of cooling, 6,000 BTUh of heating at 47°F, 180 CFM of airflow, and two-stage compressor operation. Two-stage operation means longer, gentler cycles in both modes.
In heating mode, two-stage operation helps hold steadier indoor temperatures through the shoulder seasons. On cold days, the unit delivers 16,400 BTUh at 17°F, and a backup heat kit of up to 15 kW covers the rest. Size the kit to your winter design temperature and electrical service.
Ideal for: Mid-size all-electric homes, double-wide manufactured homes, and small offices in moderate climates that want two-stage comfort.

Frequently Asked Questions
What does the 2.5 ton GPHM53031 add over the 2 ton?
It adds a two-stage compressor, raises cooling from 24,000 to 29,600 BTUh and heating at 47°F from 22,600 to 28,600 BTUh, and increases airflow to 980 CFM. Efficiency rises to 15.2 SEER2. Electrical is 21.5 MCA with a 30 amp breaker.
Why does two-stage operation matter in a heat pump?
On low stage, the heat pump runs longer at reduced output. That keeps indoor temperatures steadier, reduces on/off cycling, and improves dehumidification in cooling mode. Full capacity is available on peak days.
Can the GPHM53031 use a 15 kW heat kit?
Yes. Size 30 is approved for the HKTPD151 15 kW kit. On a single-point connection, Goodman lists 95.72 MCA and a 100 amp maximum overcurrent device.
How much R-32 does the 2.5 ton GPHM5 contain?
The GPHM53031 is factory charged with 124 oz. of R-32 refrigerant.
What is the cold-weather COP of the GPHM53031?
Goodman rates it at a 2.30 COP and 16,400 BTUh at 17°F, and a 3.48 COP at 47°F.
How much heat does a 10 kW kit produce on 208V power?
Heat kits are rated at 240V. Goodman's correction factor at 208V is 0.76, so a 10 kW kit delivers about 7.6 kW. At 230V, the factor is 0.93.
