Description
The Goodman GPHM33031 is a 2.5-ton packaged heat pump from the GPHM3 R-32 Series, offering efficient all-electric heating and cooling in a compact, self-contained unit. With a cooling capacity of 27,400 BTU/h and a heating capacity of 26,000 BTU/h (at 47°F), this rooftop or ground-mount system delivers reliable year-round comfort. Rated at 13.4 SEER2 and 6.7 HSPF2, the GPHM33031 uses advanced R-32 refrigerant for improved environmental performance and system efficiency. This model features a durable cabinet design, enhanced airflow capabilities, and integrated performance controls for optimal system operation in various climates.
Performance
The GPHM33031 is engineered for consistent performance with a single-stage scroll compressor and an energy-efficient 5-speed ECM blower motor. These components deliver smooth, responsive temperature control with airflow ranging from 859 to 1,463 CFM depending on external static pressure. The aluminum MicroChannel condenser coil enhances heat transfer efficiency while reducing refrigerant volume and corrosion risk. With a 10.6 EER2 and carefully tuned air distribution, this unit maintains effective output even during peak load conditions, making it ideal for climates requiring moderate seasonal heating and cooling.
Smart Features
While not Wi-Fi enabled out of the box, the GPHM33031 is fully compatible with a wide range of smart thermostats and zoning systems for optimized energy control and scheduling. Its ECM motor supports multiple airflow profiles, making it adaptable to building-specific configurations and smart zoning applications. Compatible thermostats can further enable demand-controlled ventilation and remote operation, giving property managers and homeowners control and visibility over energy use and occupant comfort. The unit’s internal control board also supports diagnostics to streamline system monitoring and maintenance.
Comfort & Noise
This model offers dependable comfort and quiet performance, operating at approximately 76 dBA. Its ECM motor delivers smoother transitions between fan speeds, reducing sound during start-up and operation. Air delivery is optimized through precise blower control, helping maintain consistent indoor temperatures while minimizing drafts or over-cooling. The unit’s design promotes better airflow across the evaporator and condenser coils, maximizing heat exchange efficiency while limiting sound levels, even under high external static pressure conditions.
Use Case Fit
The GPHM33031 is an excellent fit for residential, multi-family, and light commercial applications where space savings and efficient year-round comfort are priorities. Its single-package rooftop design simplifies system placement in urban or constrained settings. The 2.5-ton capacity is ideally suited for mid-sized homes, duplexes, apartment units, and smaller retail or office buildings. With R-32 refrigerant and compliant SEER2/HSPF2 ratings, it meets energy codes in most U.S. climate zones, particularly in the South, Southwest, and parts of the West and Mid-Atlantic.
Value & Reliability
Built for long-term durability, the GPHM33031 features a heavy-gauge galvanized steel cabinet with a full-perimeter base pan and louvered coil protection. Its MicroChannel coil design not only improves efficiency but also offers reduced refrigerant charge requirements and simplified serviceability. Goodman’s reputation for field-tested reliability and accessible service components ensures contractors and property managers can expect lower lifetime maintenance costs. The unit is factory-tested for performance and equipped with high- and low-pressure protection to guard against refrigerant-related failures.
Summary Wrap-Up
For property owners, contractors, and commercial professionals seeking a balanced, efficient, and environmentally advanced heat pump system, the Goodman GPHM33031 is a standout solution. With 13.4 SEER2 and 6.7 HSPF2 performance, R-32 refrigerant, and a quiet, high-capacity ECM airflow system, it delivers year-round comfort in a compact footprint. Whether retrofitting existing spaces or designing for new construction, this unit provides a dependable and forward-thinking option for sustainable comfort and HVAC efficiency.
