This Goodman Dual Fuel System pairs the GZV6SA4810A 4-ton variable-speed inverter-driven R-32 heat pump condenser with the CAPEA6030C3 upflow/downflow cased evaporator coil and the GDVM970804CN 97% AFUE modulating gas furnace. Rated at 16.2 SEER2 and 8.1 HSPF2 under AHRI Certificate #215488372, this matched system delivers variable-speed heat pump cooling and heating with gas furnace backup for sustained comfort in all climate conditions. The system uses R-32 refrigerant (GWP 675), a next-generation low-GWP alternative to R-410A that supports improved thermodynamic efficiency and reduced environmental impact.

System Components
- Outdoor Condensing Unit: Goodman GZV6SA4810A — 4-ton variable-speed inverter-driven R-32 heat pump with side-discharge cabinet, swing compressor, and EEV metering. Cold Climate rated with quiet-mode operation (as low as 45 dBA).
- Indoor Evaporator Coil: Goodman CAPEA6030C3 — Upflow/Downflow cased all-aluminum evaporator coil with factory-installed EEV, 21" cabinet width, and R-32-optimized circuitry. 21" depth for easier attic/closet access.
- Gas Furnace: Goodman GDVM970804CN — 80,000 BTU/h input / 77,600 BTU/h output, 97% AFUE, modulating gas valve, variable-speed ecm blower motor, downflow/horizontal configuration.
Pro-Installer Tip: When installing the GZV6SA4810A with the GDVM970804CN condensing furnace in a dual fuel configuration, route the condensate drain line from the secondary heat exchanger with a minimum 1/4" per foot slope to prevent condensate pooling that can corrode the collector box over time. In attic or horizontal installations, use a condensate pump or secondary drain pan with a float switch wired to the R-terminal to shut down the system if the primary drain fails — this prevents water damage that typically triggers a service call 6-12 months after installation. Verify the PVC flue vent termination meets NFPA 54/ANSI Z223.1 clearance requirements from operable windows and air intakes using a tape measure and level, and confirm combustion air supply sizing with a Manual D calculation or local code compliance check.
Key Benefits
- Variable-Speed Inverter Efficiency: The GZV6SA4810A uses variable-speed swing compressor technology to ramp output up or down based on demand, achieving up to 16.2 SEER2 and 8.1 HSPF2 — reducing energy consumption compared to single-stage systems that cycle between full-on and full-off.
- R-32 Low-GWP Refrigerant: R-32 has a Global Warming Potential of 675, approximately 68% lower than R-410A (GWP 2,088). R-32 also provides approximately 10% higher volumetric capacity than R-410A, enabling smaller compressor displacements for equivalent cooling output.
- Quiet-Mode Operation: The outdoor unit features three selectable quiet-mode levels that reduce sound output to as low as 45 dBA sound pressure at 3 feet — approaching background noise levels for residential neighborhoods and suitable for installations near bedrooms or property lines.
- EEV-Matched Indoor Coil: The CAPEA6030C3 coil features a factory-installed electronic expansion valve (EEV) that precisely meters refrigerant flow across a wider range of operating conditions than fixed-orifice or standard TXV metering, supporting stable superheat and optimal heat transfer.
- Dual Fuel Flexibility: This system automatically switches between electric heat pump operation and gas furnace heating based on outdoor temperature and the installer-configured balance point, allowing the homeowner to use the most cost-effective heating source as conditions change.
- Cold Climate Heat Pump Operation: The GZV6SA4810A is rated for heating operation down to -10°F outdoor ambient, providing heat pump capacity even in extreme cold before the gas furnace takes over — reducing reliance on fossil fuel heating in moderate winter conditions.
