Goodman 5 Ton 15.2 SEER2 Dual Fuel System Overview
This AHRI-certified dual fuel system (Certificate #215447283) pairs the Goodman GZV6SA6010 5-ton R-32 variable-speed heat pump with the GRVT961005CN 100,000 BTU/h 96% AFUE gas furnace and the CHPEA4830D3 cased horizontal evaporator coil. Rated at 15.2 SEER2 and 8.2 HSPF2, this matched system delivers efficient year-round comfort by automatically switching between electric heat pump operation and gas furnace heating based on outdoor conditions.

- GRVT961005CN — 100,000 BTU/h Input (96,100 BTU/h Output) 96% AFUE Two-Stage Natural Gas Gas Furnace. Variable-Speed ECM circulator blower motor. Downflow configuration. Cabinet Dimensions: 21" W x 28-7/8" D x 34-1/2" H. Direct Vent (Category IV) venting (2"-3").
Pro-Installer Tip
Technical Friction: Downflow furnace installations with this 100,000 BTU two-stage gas furnace require careful attention to combustion air routing and condensate management. In tight closet or garage applications, the 21" cabinet width can create clearance conflicts with the R-32 refrigerant line connections on the CHPEA4830D3 evaporator coil above.
Long-Term Prevention: Verify the condensate trap is installed per manufacturer instructions and confirm the drain slope before startup. R-32 systems operating at higher discharge pressures than R-410A predecessors will produce more condensate at peak cooling. A failed drain in a downflow application means water damage to the heat exchanger and burner assembly — the most expensive callback in HVAC.
Expert Validation: Use a digital manometer to confirm negative pressure in the combustion chamber during operation. Target -0.02" to -0.10" W.C. at the draft inducer outlet. Document this reading on the commissioning report alongside your micron gauge evacuation record (500 microns or below, held for 10 minutes minimum with R-32).
Professional Standard: This system uses R-32 refrigerant (GWP 675), which is classified as A2L (mildly flammable). Ensure compliance with ASHRAE 15 and local mechanical codes for A2L refrigerant charge limits in occupied spaces. Many jurisdictions now require leak detection equipment for A2L installations.
Key Performance Benefits
- Dual Fuel Efficiency: Combines 15.2 SEER2 / 8.2 HSPF2 heat pump performance with 96% AFUE gas furnace backup, automatically selecting the most cost-effective heating source based on outdoor conditions.
- R-32 Low-GWP Refrigerant: R-32 has a Global Warming Potential (GWP) of 675 — approximately 68% lower than R-410A (GWP 2088). R-32 also provides approximately 10% better volumetric cooling capacity, contributing to system efficiency gains.
- Variable-Speed Compressor Technology: The inverter-driven variable-speed swing compressor modulates output from approximately 25% to over 100% capacity, matching the exact thermal load for reduced energy consumption and tighter temperature control (±1°F) compared to single-stage or two-stage systems.
- Precise Airflow Management: The Variable-Speed ECM blower motor provides optimized airflow across heating, cooling, and continuous fan modes, reducing hot/cold spots and lowering operating noise compared to PSC motors.
- Two-Stage Gas Valve: Two-stage gas valve operates at 70% capacity on low fire for most heating demand, reducing temperature swings and gas consumption while reserving full output for the coldest conditions.
- AHRI Certified Match: All components are AHRI-certified as a matched system (Certificate #215447283), ensuring rated performance is achieved when installed according to manufacturer specifications.
