Description
The Goodman GPHH54831 is a 4-ton, all-in-one packaged heat pump system from the high-performance GPHH5 Series. Designed for rooftop or ground-level mounting, this unit delivers 48,000 BTU of nominal cooling and heating capacity while using the environmentally advanced R-32 refrigerant. With energy efficiency ratings of up to 14.3 SEER2 and 7.0 HSPF2, it meets or exceeds DOE 2023 regional requirements in most applications. The GPHH54831 is built for long-lasting performance and simplified service access, making it ideal for a wide range of residential and light commercial installations. This self-contained system integrates heating and cooling into a single footprint, offering an efficient solution where indoor equipment space is limited.
Performance
This model is engineered for performance, featuring a high-efficiency scroll compressor and optimized airflow to maintain consistent comfort even in challenging climates. The dual-stage compressor allows the unit to operate at a lower capacity during milder conditions, improving part-load efficiency and reducing utility costs. The all-aluminum evaporator and condenser coils enhance thermal transfer and corrosion resistance, ensuring long-term system durability. With up to 3,975 CFM airflow across four blower speed settings, the GPHH54831 adapts to diverse ducting scenarios while maintaining system balance. Engineered for superior performance in both heating and cooling modes, it ensures year-round comfort with minimal energy consumption.
Smart Features
The GPHH54831 is fully compatible with most advanced thermostats, including Wi-Fi-enabled and smart home systems. Its low-voltage terminal strip simplifies integration with zoning panels or smart thermostats for precise, room-by-room control. The control board is designed with fault code LED diagnostics and connection points for accessories such as UV lights or humidistats. This model allows for seamless upgrades into demand-controlled ventilation systems, zoning controls, and energy monitoring solutions. Homeowners and building operators can enjoy remote temperature control and energy reporting when paired with compatible smart thermostats.
Comfort & Noise
With sound levels as low as 76 dBA, the GPHH54831 delivers quiet performance ideal for residential neighborhoods, schools, and multi-family properties. It balances airflow across four blower speeds to maintain optimal comfort throughout the space without unnecessary noise or drafts. The dual-stage compressor not only improves efficiency but also enhances comfort by reducing temperature swings and dehumidifying more effectively at part load. Its ECM blower motor ensures smooth operation with improved static pressure performance and quieter startup and shutdown sequences. This unit is optimized to keep interior spaces consistently comfortable without the intrusion of operational noise.
Use Case Fit
Designed for flexibility, the GPHH54831 meets the heating and cooling needs of residential homes, multi-family properties, and light commercial spaces up to approximately 2,500–3,000 sq. ft., depending on insulation and regional climate. It’s particularly suited to mixed and warm climates where heat pump efficiency can offset the need for fossil fuel-based systems. This model performs well in both humid southeastern U.S. environments and milder southwestern zones. Its compact footprint and horizontal/vertical airflow options make it a top choice for rooftop replacements or slab-mounted new construction projects. Property managers will appreciate its low-maintenance design and multi-application versatility.
Value & Reliability
Built with Goodman’s commitment to quality, the GPHH54831 features a durable, galvanized steel cabinet with a powder-paint finish tested for 500 hours of salt spray. It includes service-friendly access panels for rapid diagnostics and maintenance. The unit’s aluminum coils are resistant to corrosion and electrochemical degradation, and its factory-installed TXV ensures accurate refrigerant flow in varying conditions. The dual-stage scroll compressor provides dependable, efficient operation year-round. Combined with its environmentally responsible R-32 refrigerant and rugged construction, the GPHH54831 offers long-term value with reduced service interruptions and lower lifetime operating costs.
