This Goodman 3-Ton Dual Fuel System pairs the GZV9SA361C variable-speed, inverter-driven R-32 heat pump condenser with the GRVT801005CN 80% AFUE two-stage, variable-speed ecm gas furnace and CAPEA6030D3 Cased Upflow/Downflow A-Coil. This AHRI-certified combination (Certificate #216699924) achieves up to 19.0 SEER2 / 9.2 HSPF2 / 11.7 EER2, qualifying for ENERGY STAR® Most Efficient 2025 and Cold Climate Heat Pump (ccHP) designation. The system operates on low-GWP R-32 refrigerant (GWP: 675), supporting the EPA AIM Act phasedown requirements and potentially qualifying for federal energy efficiency tax credits under IRS Section 25C.

System Components
- GZV9SA361C (GZV9SA361C*) — 3-Ton Variable-Speed, Inverter-Driven, Side-Discharge R-32 Heat Pump Condenser with dual variable-speed swing compressors, EEV metering, quiet-mode capability (as low as 45 dBA), and hot gas base pan defrost down to 5°F. 208-230V / 1 Phase / 60 Hz.
- GRVT801005CN — 100,000 BTU/h Input, 80% AFUE, Downflow, Two-Stage, Variable-Speed ECM Gas Furnace. Heavy-duty aluminized-steel tubular primary heat exchanger.
- CAPEA6030D3 — Cased Upflow/Downflow A-Coil, Upflow/Downflow configuration, 24½"W x 21"D x 30"H cabinet. All-aluminum 7mm tube coil with R-32 optimization and factory-installed R-32 refrigerant sensor.
⚙ Pro-Installer Tip
[Technical Friction] The GZV9S side-discharge condenser paired with a downflow furnace in a 21" cabinet creates tight clearance requirements, especially in garage or closet installations where the coil-to-furnace fitment (1.75 fit) must be verified before brazing. R-32's slightly higher discharge pressure (compared to R-410A) demands precise line set sizing—the ⅜" liquid / ⅞" suction specification is non-negotiable on this 3-ton system.
[Long-Term Prevention] After final brazing, pull the system to 500 microns or below and perform a 10-minute decay test. R-32's lower charge tolerance means even a minor leak that would be masked in an R-410A system will cause EEV hunting and short-cycling within the first cooling season. Verify subcooling at the service valve reads 11±1°F per the spec sheet—this single measurement prevents the #1 warranty callback on variable-speed inverter systems.
[Expert Validation] Use a digital manifold with R-32 PT chart preloaded (Testo 570s or Fieldpiece SMAN480) and a calibrated micron gauge (not a compound gauge). The GZV9S EEV auto-controls superheat, so if superheat readings are erratic during commissioning, the issue is charge or airflow—not the valve.
[Professional Standard] EPA Section 608 certification is required for R-32 handling (same as R-410A). Per 2024 EPA AIM Act regulations, R-32 systems must use dedicated recovery equipment. Verify local jurisdiction accepts R-32 installations—most have adopted the 2021+ IMC/UMC codes that list A2L refrigerants, but some municipalities lag. Always confirm with the Authority Having Jurisdiction (AHJ) before install.
Key Performance Benefits
- Cold Climate Heat Pump Certification: The GZV9S operates down to -20°F ambient, providing reliable heat pump heating in extreme cold without solely relying on auxiliary heat, reducing energy consumption in northern climates.
- Variable-Speed Inverter Efficiency: The swing compressor modulates capacity from approximately 25% to 100% (and boost mode), maintaining tighter temperature control (±0.5°F) and reducing on/off cycling compared to single-stage or two-stage systems.
- Quiet Operation: The GZV9S features three selectable quiet-mode levels with sound output as low as 45 dBA in quiet mode—comparable to a quiet library. Standard cooling mode measures approximately 59 dBA @ 5 ft (1 reflective surface).
- Low-GWP R-32 Refrigerant: R-32 has a Global Warming Potential of 675, approximately 68% lower than R-410A (GWP 2,088). This reduces the system's direct environmental impact while also improving thermodynamic efficiency due to R-32's higher volumetric capacity.
- Dual Fuel Flexibility: The system automatically switches between heat pump and gas furnace operation at a configurable balance point, optimizing energy cost based on local utility rates and outdoor temperature. The 80% AFUE furnace provides efficient supplemental and backup heating.
- EEV Metering with Auto-Controlled Superheat: The electronic expansion valve in the GZV9S condenser provides precise refrigerant metering across the full modulation range, eliminating the performance compromises of fixed-orifice or standard TXV metering at part-load conditions.
