Goodman GPHM34831 (4-Ton) R-32 Packaged Heat Pump – 13.4 SEER2

Model: GPHM34831 | Type: R-32 packaged heat pump | Nominal size: 4 ton Goodman GPHM3 is an 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: 13.4 SEER2, 10.6 EER2, 6.70 HSPF2 Cooling capacity: 46,500 BTU/h total / 34,875 BTU/h sensible Heating capacity: 45,500 BTU/h @ 47°F (COP 3.44); 24,800 BTU/h @ 17°F (COP 2.18) Compressor: Scroll (Single-stage); RLA 19.39, LRA 138.4 Indoor airflow: 1,600 nominal CFM with multi-speed ECM blower (5 speeds); blower FLA 5.4; motor 3/4 HP Refrigerant: R-32; factory charge 153 oz (A2L / mildly flammable—install and service per applicable codes by qualified technicians) Electrical: 1-phase 208-230V, 60 Hz; minimum circuit ampacity (MCA) 31.64; max overcurrent protection (MOP) 50 Sound rating: 79 dB Weight: 460 lb operating / 490 lb shipping Certifications: AHRI Certified; UL Listed Cooling details Provides 46,500 BTU/h of total cooling with 34,875 BTU/h of sensible capacity. EER2 (10.6) is measured at a single test condition, while SEER2 (13.4) 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: 45,500 BTU/h at 47°F and 24,800 BTU/h at 17°F. The COP values (47°F: 3.44, 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 Piston; condenser Piston. 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. Compressor: single-stage scroll. Heavy-gauge galvanized-steel cabinet with 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: Large Unit dimensions: W 47 in × D 51 in × Height A 40 in (Height B 42¾ in) Duct openings: Supply 16 x 18 (W×H) / Return 16 x 18 (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.
