Description
The Goodman GPHM34231 is a 3.5-ton (42,000 BTU/h cooling, 37,000 BTU/h heating) packaged heat pump in the GPHM3 R‑32 Series, engineered for homeowners, contractors, and facility managers. With 13.4 SEER2 and 6.7 HSPF2 ratings, this unit complies with current DOE energy standards while using low-GWP R‑32 refrigerant. It is available in multi-position configurations (horizontal or downflow) and operates on 208–230 V single-phase power. This factory-assembled unit combines durability with system flexibility in a streamlined package.
Performance
The GPHM34231 pairs a single-stage scroll compressor with a multi-speed ECM blower motor, delivering smooth, efficient operation. Cooling capacity is rated at 42,000 BTU/h, while heating capacity reaches 37,000 BTU/h, suited for moderate to warm climates. The unit’s airflow performance adapts via the ECM motor to match various ductwork and static pressure conditions. Supporting efficiency is a 10.6 EER2 rating, reflecting solid performance during peak load periods.
Smart Features
Although the GPHM34231 is not Wi‑Fi enabled out of the box, it integrates seamlessly with aftermarket smart thermostats and zoning systems. Its ECM blower supports advanced control strategies like zoning, demand control ventilation, and remote scheduling. The bundled control board also provides diagnostic support, enabling contractors and maintenance teams to monitor performance and troubleshoot remotely.
Comfort & Noise
Designed for quiet operation, the GPHM34231 features an insulated blower compartment, vibration-resistant scroll compressor, and noise-minimizing ECM fan control. Sound levels are in the low to mid-70 dBA range, making the unit well-suited for residential rooftops or noise-sensitive commercial settings. The unit provides stable airflow without disruptive fluctuations, promoting consistent indoor comfort.
Use Case Fit
This unit is ideal for residential, multi-family, and light commercial environments that demand space-efficient, all-in-one HVAC solutions. Its 3.5-ton capacity is suited to medium-to-large homes, multi-unit buildings, and small commercial spaces. The convertible airflow design ensures installation flexibility across rooftop or mechanical-room environments. It meets energy code requirements across U.S. climate zones, including states with aggressive energy standards.
Value & Reliability
Built with a galvanized-steel cabinet and corrosion-resistant coil design, the GPHM34231 is engineered for longevity. The combination of scroll compressor and ECM blower minimizes wear, offering reliable, energy-efficient service. Service panels allow convenient access for diagnostics and maintenance, while AHRI certification guarantees verified performance metrics.
Summary Wrap-Up
For direct consumers, contractors, and facility professionals, the Goodman GPHM34231 delivers a strong blend of energy efficiency, flexibility, and environmental responsibility. Its R‑32 refrigerant, DOE-compliant SEER2/HSPF2 ratings, and quiet operation make it a high-value, future-ready HVAC choice. This unit suits a variety of property types, offering dependable comfort and reduced operating costs.
