Description
The Goodman GPHM54831 is a 4-ton all-in-one packaged heat pump that delivers consistent, efficient heating and cooling performance in a self-contained unit. Offering a cooling capacity of 47,000 BTU and a heating capacity of 46,000 BTU, this model achieves up to 14.3 SEER2 and 7.0 HSPF2, meeting DOE 2023 efficiency standards. Designed for horizontal and rooftop installations, it runs on R-32 refrigerant, which offers lower global warming potential and better thermodynamic performance than legacy refrigerants. This model belongs to the GPHM5 Series and is engineered for year-round comfort in warm and moderate climate regions. With its compact, durable design and energy-focused specs, the GPHM54831 is built to serve both residential and light commercial applications.
Performance
At the core of the GPHM54831 is a high-efficiency scroll compressor that delivers smooth and dependable performance while reducing the number of moving parts compared to piston-based designs. The unit features a copper tube/aluminum fin condenser and evaporator coil assembly for maximum heat transfer and reliability. An ECM (electronically commutated motor) blower ensures airflow flexibility and efficiency, with airflow capacities up to 1,600 CFM. This design optimizes system responsiveness and temperature regulation across various building loads. Combined, these components deliver excellent operational stability, reduced energy usage, and lower annual operating costs.
Smart Features
The GPHM54831 supports smart functionality through compatibility with programmable and smart thermostats, enabling users to control temperature schedules and energy use remotely. Although the unit does not come with native Wi-Fi or IoT technology, its low-voltage controls are designed to integrate seamlessly with third-party smart HVAC systems. This opens up options for zoning, time-of-use energy management, and integration into smart home platforms. Contractors and property managers can also implement controls for multi-unit configurations in commercial or multifamily buildings, enhancing overall system flexibility.
Comfort & Noise
Engineered for comfort, the GPHM54831 offers balanced airflow and quiet operation with an approximate sound level of 75 dBA. The ECM blower motor not only enhances energy efficiency but also improves comfort by providing steady, variable airflow that avoids temperature swings and reduces indoor drafts. The unit's coil design and refrigerant metering ensure effective humidity control and fast response during peak conditions. Whether installed on a rooftop or ground-level pad, the GPHM54831 minimizes noise transmission and maximizes thermal comfort for occupants across all seasons.
Use Case Fit
The GPHM54831 is ideal for single-family residences, small commercial buildings, multi-unit properties, and retrofit projects requiring a 4-ton capacity system. Its electric-only operation and R-32 refrigerant make it a strong fit for markets shifting away from natural gas or requiring low-GWP refrigerants, such as California, Arizona, Florida, and Texas. The unit’s compact footprint and dual-position airflow configuration (horizontal and rooftop) allow for installation in space-constrained environments without sacrificing system performance. Whether upgrading an aging HVAC system or specifying equipment for new construction, this model provides climate flexibility and operational reliability.
Value & Reliability
Goodman builds the GPHM5 Series—including the GPHM54831—for durability and long-term value. Its heavy-gauge galvanized steel cabinet is finished with a baked-on powder coating for corrosion resistance, while the fully louvered panels protect the coil against debris and damage. Service access panels provide fast, straightforward component access for quicker diagnostics and routine maintenance. Factory-installed features like a suction-line accumulator, filter drier, and high/low pressure switches further support system longevity and compressor protection. Whether managing a single property or a multi-unit portfolio, contractors and owners benefit from dependable HVAC performance and reduced service overhead.
