This Goodman 3-Ton Dual Fuel System pairs the GZV6SA3610* variable-speed heat pump with the GMVM971005CN 97% AFUE gas furnace and the CAPEA3626C3 evaporator coil. Rated at 16.0 SEER2 and 8.5 HSPF2, this AHRI-certified combination (Certificate #215447219) delivers efficient year-round comfort using R-32 refrigerant. The system automatically switches between electric heat pump and gas furnace heating based on outdoor conditions, optimizing energy use across all climate zones.

System Components
- Outdoor Heat Pump Condenser: Goodman GZV6SA3610* — 3-Ton variable-speed inverter-driven R-32 heat pump with swing compressor, EEV metering, and digitally commutated condenser fan motor. Sound power as low as 45 dBA in quiet mode.
- Evaporator Coil: Goodman CAPEA3626C3A* — 3-Ton cased Upflow/Downflow all-aluminum evaporator coil with integrated EEV, factory-installed R-32 sensor, and thermoplastic drain pan with secondary drain connection.
- Gas Furnace: Goodman GMVM971005CNB — 97% AFUE, 100,000 BTU/h input, Upflow/Horizontal configuration with Modulating gas valve, Variable-Speed ECM blower motor, aluminized-steel primary and stainless-steel secondary heat exchangers, and integrated ComfortBridge communicating technology. Natural Gas.
Pro-Installer Tip
The Technical Friction: Dual fuel changeover calibration with a modulating furnace and variable-speed heat pump demands precise low-ambient lockout configuration. The outdoor unit's compressor staging must align with the furnace's modulating gas valve to prevent short-cycling during the transition temperature range (typically 30-40 deg.F).
The Long-Term Prevention: During commissioning, verify the balance-point temperature setting through the communicating thermostat interface. Setting this too high forces unnecessary gas consumption; too low risks compressor strain in extreme cold. A properly calibrated balance point prevents nuisance lockout calls and keeps operating costs predictable through the first full heating season.
The Expert Validation: Use the CoolCloud app to monitor compressor frequency and furnace modulation rate simultaneously during commissioning. Verify the subcooling target of 15 +/- 1 deg.F at the outdoor service valve with a digital manifold gauge set before sealing up the system.
The Professional Standard: Confirm the furnace flue termination meets local building code clearance requirements for 2-pipe direct-vent installations (typically 12" from any openable window). In California, verify the unit's Low NOx certification meets the regional air quality district requirements — this GMVM97 model cannot be installed in SCAQMD or SJVAPCD jurisdictions.
Key System Benefits
- Dual Fuel Versatility: Automatic switching between electric heat pump and 97% AFUE gas furnace heating optimizes energy costs based on outdoor temperature and local utility rates.
- High Seasonal Efficiency: 16.0 SEER2 cooling and 8.5 HSPF2 heating ratings reduce annual energy consumption compared to standard-efficiency systems, potentially qualifying for federal tax credits and utility rebates.
- Variable-Speed Comfort: Both the outdoor compressor and indoor blower operate at variable speeds, delivering precise temperature and humidity control while minimizing noise and temperature swings.
- Low-GWP R-32 Refrigerant: R-32 offers a 68% lower global warming potential than R-410A and provides higher volumetric cooling capacity, supporting the industry transition under the AIM Act phasedown schedule.
- Communicating System Integration: ComfortBridge technology enables the thermostat, furnace, and outdoor unit to share operational data in real time, automatically adjusting airflow, staging, and balance-point settings for optimized performance.
