This Goodman Dual Fuel System pairs the GZV6SA1810A variable-speed inverter-driven heat pump condenser with the CHPEA2422B3 evaporator coil and the GDVT800803BX 80% AFUE gas furnace for comprehensive year-round heating and cooling. Rated at 19 SEER2 and 8.8 HSPF2 for the heat pump side, and 80,000 BTU input on the furnace, this 1.5-ton R-32 system delivers efficient performance in both moderate and extreme cold conditions. The dual fuel design automatically switches between electric heat pump operation and gas furnace heating based on outdoor temperatures, optimizing energy costs throughout the season. AHRI Certificate Number: 215439733. This system features a Low NOx furnace compliant with SCAQMD Rule 1111 for Southern California and other regulated air quality districts.

System Components
- GZV6SA1810A — Goodman 1.5-Ton Variable-Speed Inverter-Driven R-32 Heat Pump Condenser (19 SEER2 / 8.8 HSPF2 / 12 EER2)
- CHPEA2422B3 — Goodman Cased Horizontal Evaporator Coil with Internal EEV (22" W x 21" D x 17½" H, All-Aluminum, R-32 Optimized)
- GDVT800803BX — Goodman 80% AFUE 80,000 BTU Downflow/Horizontal Two-Stage Gas Furnace with Variable-Speed ECM Motor, Low NOx
Pro-Installer Tip
Technical Friction: The R-32 refrigerant in this system operates at slightly higher discharge pressures than R-410A, and the GZV6SA1810A's side-discharge configuration requires 12" minimum clearance on the discharge side. When paired with a Low NOx or Ultra Low NOx furnace in a California installation, combustion air intake routing can conflict with the condenser's required clearance envelope — particularly in tight side-yard setups common in Southern California tract homes.
Long-Term Prevention: Install a field-installed bi-flow filter drier on the liquid line and verify subcooling at 10±1°F at the service valve after the initial charge adjustment. Improper subcooling on a 1.5-ton inverter system leads to compressor liquid slugging at low-speed operation, which typically surfaces as a nuisance fault code 6–12 months post-install during mild shoulder-season conditions when the compressor runs at minimum speed.
Expert Validation: Use a digital manifold gauge (Testo 557s or equivalent) with R-32 pressure-temperature tables loaded — R-410A tables will not give accurate superheat/subcooling readings for this refrigerant. Verify the dual fuel switchover point is set correctly in the communicating thermostat; a common callback is the system defaulting to electric heat below 35°F when the furnace should be handling the load.
Professional Standard: R-32 systems require EPA Section 608 certification for handling. Ensure all flare connections are made with a calibrated torque wrench per manufacturer specifications — the GZV6S uses front-sealing service valves. In SCAQMD jurisdictions, verify the furnace NOx rating matches the local air quality district requirements before commissioning.
Key Benefits
- High-Efficiency R-32 Refrigerant: R-32 has a Global Warming Potential (GWP) of 675, approximately 68% lower than R-410A (GWP 2088), reducing the system's direct environmental impact while maintaining equivalent cooling and heating performance at 19 SEER2 / 8.8 HSPF2.
- Variable-Speed Inverter Compressor: The swing compressor in the GZV6SA1810A modulates capacity from minimum to maximum output, reducing temperature swings, improving humidity control, and lowering energy consumption compared to single-speed or two-stage systems during partial-load conditions.
- Quiet Operation with Quiet Mode: Normal operating sound level of 61 dBA, with a three-level Quiet Mode that can reduce sound output to as low as 40 dBA — suitable for installations near bedrooms, patios, or property lines with noise ordinance concerns.
- Cold Climate Heat Pump Capability: ENERGY STAR® Cold Climate certified, the GZV6SA1810A operates in heating mode down to -10°F ambient, providing 13,000 BTU/h at 5°F outdoor temperature for reliable heat pump operation in northern climates without auxiliary heat dependency.
- Dual Fuel Cost Optimization: Automatically transitions between heat pump operation (higher COP at moderate temperatures) and gas furnace heating (more economical at extreme cold) based on a field-adjustable switchover temperature, delivering the lowest combined operating cost across the full heating season.
- Two-Stage Gas Furnace: The 80% AFUE furnace operates at a low-fire setting for most of the heating season, engaging high-fire only during peak cold events — this reduces gas consumption and provides more even temperatures than single-stage operation.
- Electronic Expansion Valve (EEV): The EEV provides continuous, precise refrigerant metering that adjusts in real-time to changing load conditions — a significant upgrade over fixed-orifice pistons or standard TXVs for maintaining optimal system efficiency across the full operating range.
