Goodman GPHM52431 (2-Ton) R-32 Packaged Heat Pump – 14.4 SEER2

Model: GPHM52431 | Type: R-32 packaged heat pump | Nominal size: 2 ton Goodman GPHM5 is a higher-efficiency R-32 packaged heat pump (all-in-one outdoor unit) built for ducted cooling and heating with horizontal or downflow airflow configurations. It’s designed for applications where the outdoor unit connects directly to supply/return ductwork. Sizing should be done with a proper load calculation (tonnage is capacity, not a guaranteed square-foot number). Specs at a glance Efficiency ratings: 14.4 SEER2, 11.4 EER2, 6.70 HSPF2 Cooling capacity: 24,000 BTU/h total / 18,720 BTU/h sensible Heating capacity: 22,600 BTU/h @ 47°F (COP 3.60); 12,800 BTU/h @ 17°F (COP 2.18) Compressor: Scroll (Single-stage); RLA 10.62, LRA 56.5 Indoor airflow: 800 nominal CFM with multi-speed ECM blower (5 speeds); blower FLA 3.8; motor 1/2 HP Refrigerant: R-32; factory charge 102 oz (A2L / mildly flammable—install and service per applicable codes by qualified technicians) Electrical: 1-phase 208-230V, 60 Hz; minimum circuit ampacity (MCA) 18.7; max overcurrent protection (MOP) 25 Sound rating: 76 dB Weight (listed): 376 lb Certifications: AHRI Certified; UL Listed Cooling details Provides 24,000 BTU/h of total cooling with 18,720 BTU/h of sensible capacity. EER2 (11.4) is measured at a single test condition, while SEER2 (14.4) represents seasonal efficiency over a range of conditions—use both to compare models and estimate operating costs. Heating details Heat pump output is listed at two common rating points: 22,600 BTU/h at 47°F and 12,800 BTU/h at 17°F. The COP values (47°F: 3.60, 17°F: 2.18) indicate heating efficiency at those points. In colder climates, many installations add a field-installed electric heat kit for auxiliary/emergency heat. Airflow, comfort & filtration Multi-speed ECM indoor blower helps match airflow to duct design and comfort needs. Convertible airflow supports horizontal or downflow duct connections (field-configurable). Metering device: evaporator TXV; condenser TXV. Filtration approach depends on your installation (internal/external filter racks are available as accessories). Construction & durability Condenser coil: copper tube/aluminum fin. Evaporator coil: all-aluminum (2–4 ton models). Liquid-line filter drier included. Compressor: one-stage scroll (2.0 ton). Heavy-gauge galvanized-steel cabinet with two-tone Architectural Gray powder-paint finish and foil-faced internal insulation (reinforced with fiberglass scrim). Fully insulated air-handling compartment with access panels and louvered condenser coil protection. Meets cabinet air leakage requirements when tested to ASHRAE Standard 193; when properly anchored, meets 2023 Florida Building Code unit integrity requirements for hurricane-type winds (anchor bracket kits available). Installation planning (verify before ordering) Chassis size: Medium Unit dimensions: W 47 in × D 51 in × Height A 32 in (Height B 34¾ in) Duct openings: Supply 16 x 16 (W×H) / Return 16 x 16 (W×H) Condensate drain: 3/4" NPT female connection. Downflow installs: manufacturer notes require horizontal duct covers plus either a downflow conversion kit or a downflow economizer. Electrical planning: use MCA/MOP values for breaker and wire sizing, and always verify against the unit’s nameplate (S&R plate). Use time-delay fuses or HACR-type breakers as required. Common add-ons (sold separately) Electric heat kit (field-installed) for auxiliary/emergency heat Economizer options (fresh air / ventilation) — varies by chassis Roof curb and concentric kit options — varies by chassis Filter rack options (internal downflow or external horizontal) What’s included: packaged heat pump unit only (factory charged). Thermostat/controls, ductwork, curb, economizer, and electric heat kit (if needed) are typically purchased separately and installed by a licensed HVAC professional.
