Description
The Goodman GPHM56031 is a powerful 5-ton packaged heat pump designed to deliver efficient, all-electric heating and cooling in a single, compact system. With a nominal cooling capacity of 57,500 BTU and heating capacity of 56,500 BTU, this unit achieves up to 13.4 SEER2 and 6.7 HSPF2, aligning with 2023 DOE standards. Built for rooftop or horizontal ground-mount applications, the GPHM56031 uses environmentally responsible R-32 refrigerant, which offers excellent thermodynamic efficiency and a lower global warming potential. This model is part of Goodman’s advanced GPHM5 Series, purpose-built to meet the comfort and energy demands of larger residential homes, commercial buildings, and multi-unit properties.
Performance
At the heart of the GPHM56031 is a durable scroll compressor that ensures consistent, energy-efficient performance with minimal moving parts, improving system longevity. The unit’s copper tube/aluminum fin coil configuration enhances thermal conductivity and system durability under demanding conditions. It also features a high-performance ECM blower motor, supporting up to 1,900 CFM of airflow—providing reliable distribution across large zones. This combination of high-capacity performance and system efficiency helps reduce annual energy costs while delivering fast, stable comfort in both cooling and heating seasons.
Smart Features
The GPHM56031 supports integration with a wide range of programmable and smart thermostats, giving property managers and homeowners control over temperature schedules and energy usage. Though the unit itself doesn’t have built-in Wi-Fi, its low-voltage control system enables seamless connectivity with external zoning and smart home platforms. This flexibility allows users to implement advanced automation features, remote access, and zoning configurations to improve comfort and operating efficiency—especially useful in multi-occupant or commercial environments.
Comfort & Noise
Engineered for quiet performance, the GPHM56031 produces approximately 78 dBA during operation—moderated by its scroll compressor and sound-control design. The variable-speed ECM blower delivers smoother airflow, reduces noise spikes during start-up, and supports even air distribution throughout the conditioned space. Paired with its coil design and efficient refrigerant metering, the unit helps maintain consistent indoor temperature and humidity levels. Whether operating in extreme summer heat or mild winter conditions, the GPHM56031 is optimized for comfort without excessive noise or airflow imbalance.
Use Case Fit
With its 5-ton capacity and high-performance specifications, the GPHM56031 is ideal for large single-family homes, small commercial spaces, retail buildings, and multifamily properties requiring centralized comfort. Its flexible horizontal and rooftop mounting options make it an excellent fit for both new construction and replacement projects in space-restricted environments. This model performs reliably in hot and humid climates across the South, Southeast, and Southwest regions, where electric-only HVAC systems and low-GWP refrigerants are increasingly favored by building codes and sustainability requirements.
Value & Reliability
Designed with serviceability and durability in mind, the GPHM56031 features a heavy-gauge steel cabinet with a UV-resistant powder coating and fully louvered coil guards for added protection. Factory-installed high- and low-pressure switches, a suction line accumulator, and filter drier help protect the compressor and extend system life. Access panels simplify routine maintenance, while the internal component layout is optimized for efficient diagnostics. This combination of rugged construction and smart design makes it a low-maintenance, high-reliability option for both property owners and HVAC professionals.
Summary Wrap-Up
The Goodman GPHM56031 delivers robust, all-electric comfort in a 5-ton packaged unit built for efficiency, durability, and ease of use. With 13.4 SEER2 and R-32 refrigerant, it meets today’s performance and environmental standards while offering quiet operation, smart control compatibility, and versatile installation. Whether you manage a commercial property, oversee multifamily housing, or need a powerful solution for a large residence, the GPHM56031 stands out as a high-capacity, energy-conscious HVAC investment built to deliver long-term value and dependable comfort.
