This 4-ton (48,000 BTU) model from Goodman’s advanced GPHM5 R-32 Series utilizes environmentally friendly R-32 refrigerant for reduced global warming potential (GWP) and optimized performance. Designed for rooftop or ground mount applications, it delivers a SEER2 rating of 13.4 and HSPF2 rating of 6.7, making it ideal for warm to moderate climates. The unit operates on 208/230V single-phase power and integrates key design features that promote energy efficiency, serviceability, and long-term dependability.

Performance
The GPHM54231 stands out with its energy-saving scroll compressor that ensures smooth, consistent operation across varying load conditions. The all-aluminum evaporator and condenser coils resist corrosion and enhance heat transfer, boosting both cooling and heating efficiency. With a steady-state cooling capacity of 46,000 BTU and a heating output of 45,000 BTU, this model handles year-round climate control with ease. Its multi-speed ECM indoor blower motor delivers quiet, reliable airflow while supporting multiple comfort settings. With maximum airflow up to 1,715 CFM, it’s well-suited for a range of space requirements.

Smart Features
This model supports enhanced system control through compatibility with smart thermostats and zoning systems, allowing homeowners and property managers to fine-tune comfort by area and usage. While not featuring built-in Wi-Fi, the GPHM54231 works seamlessly with connected HVAC accessories, enabling energy-saving scheduling, remote adjustments, and real-time diagnostics when paired with appropriate controls. This adaptability gives users greater flexibility in managing energy costs and tailoring comfort levels across larger homes or multi-zone buildings.

Comfort & Noise
Engineered for quieter operation, the GPHM54231 operates at just 73 dBA, helping reduce outdoor sound disturbances in residential or noise-sensitive areas. The ECM blower motor provides smoother, quieter airflow transitions compared to PSC motors, contributing to better humidity control and comfort stability indoors. Its high airflow capacity ensures even air distribution throughout the property, minimizing hot and cold spots while maintaining a consistent indoor temperature. Combined with its modern coil and compressor design, this unit delivers both performance and acoustic comfort.

Use Case Fit
With its 4-ton capacity and rugged, weather-resistant cabinet, the GPHM54231 is built for a wide range of applications—from single-family homes and duplexes to light commercial buildings and multi-family residences. It's especially well-suited for Southern and Southwestern U.S. regions where cooling demands dominate. The R-32 refrigerant not only supports low-GWP compliance, but also appeals to eco-conscious property managers and commercial developers looking to meet emerging environmental standards without sacrificing performance.

Value & Reliability
The GPHM54231 reflects Goodman’s legacy of delivering long-term value through quality engineering and performance-tested components. Its high-efficiency scroll compressor is factory-proven for durability, and the all-aluminum coil design reduces potential failure points often seen in mixed-metal systems. Additional service-friendly features like top-panel access and clearly labeled controls support easier routine maintenance, making it a cost-efficient option over the unit’s operational life for contractors and property managers alike.
