This AHRI-certified Dual Fuel System pairs the Goodman GZV6SA2410 2-ton, 18.0 SEER2, 8.5 HSPF2 variable-speed inverter-driven R-32 heat pump with the GRVT800603BN 80% AFUE two-stage gas furnace (60,000 BTU/h input) and the CHPEA2422B3 cased horizontal evaporator coil with factory-installed EEV. This combination delivers efficient all-season comfort: variable-speed heat pump operation for moderate temperatures and automatic switchover to gas furnace heating when outdoor conditions drop below the balance point. AHRI Certified Reference Number: 215487282.

System Components
- GZV6SA2410 — Goodman 2-Ton, 18.0 SEER2 / 8.5 HSPF2, Variable-Speed Inverter-Driven R-32 Side Discharge Heat Pump Condenser (23,200 BTU/h cooling, 23,200 BTU/h heating at 47°F)
- GRVT800603BN — Goodman 60,000 BTU/h Input (48,000 BTU/h Output), 80% AFUE, Two-Stage, Variable-Speed ECM, Upflow/Horizontal Gas Furnace
- CHPEA2422B3 — Goodman 2 Ton Nominal, Cased Horizontal, All-Aluminum Evaporator Coil with Factory-Installed EEV (22" W × 21" D × 17½" H)
Pro-Installer Tip
The Technical Friction: Upflow 80% AFUE furnaces with the GZV6SA2410 heat pump use a conventional metal flue venting arrangement. In tight mechanical closets, the 60,000 BTU furnace's single-wall vent connector requires minimum 6-inch clearance to combustibles — verify this against the coil height (17½") stacked above the furnace before committing to the layout.
The Long-Term Prevention: Install a combustion air proving switch if the furnace is in a confined space. Check the dual fuel changeover setpoint (typically ~35°F outdoor ambient) to ensure the system doesn't short-cycle between heat pump and gas heat during shoulder-season temperature swings, which causes premature contactor wear.
The Expert Validation: After commissioning, verify combustion with a digital combustion analyzer: CO should be below 100 ppm air-free in flue gases, and draft should read –0.02" WC or more negative at the draft hood. Confirm heat pump subcooling at 12±1°F per GZV6S specs.
The Professional Standard: EPA Section 608 certification is required for R-32 refrigerant handling. Local building codes may require a two-stage gas valve for this installation — verify with the Authority Having Jurisdiction (AHJ). R-32 has a GWP of 675, roughly 68% lower than R-410A, supporting 2025 AIM Act phase-down targets.
Key Benefits
- High-Efficiency Performance: 18.0 SEER2 and 8.5 HSPF2 ratings with variable-speed inverter technology reduce energy consumption compared to single-speed systems by running at lower speeds for longer periods, matching output to actual demand.
- R-32 Refrigerant: GWP of 675 — approximately 68% lower than R-410A (GWP 2,088). Supports 2025 EPA AIM Act HFC phase-down requirements and reduces direct greenhouse gas emission potential.
- Variable-Speed Operation: The swing compressor adjusts speed continuously rather than cycling on/off, providing tighter temperature control (±0.5°F vs. ±2°F for single-stage), reduced humidity, and lower sound levels (as low as 45 dBA in Quiet Mode).
- Dual Fuel Flexibility: Automatically switches between heat pump and 60,000 BTU/h gas furnace based on outdoor temperature, optimizing operating cost by using the most efficient heat source for current conditions.
- Communicating System: EEV-equipped indoor components work with the outdoor unit's control board to optimize refrigerant flow and system performance. Compatible with Goodman GTST connected thermostat for advanced diagnostics.
- Cold Climate Capable: ENERGY STAR Most Efficient 2025 (Cold Climate) certified. Heat pump operates down to -10°F ambient, delivering 14,200 BTU/h at 5°F for reliable heating in harsh conditions.
