Goodman 4 Ton Up to 18.0 SEER2 9.0 HSPF2 Variable-Speed Inverter Heat Pump Top Discharge All Regions R-32

High-output variable-speed efficiency for large homes — 9.0 HSPF2 heating performance in a familiar top-discharge package. The Goodman GZV9SA4810 delivers 4-ton, variable-speed inverter heating and cooling at up to 18.0 SEER2 / 9.0 HSPF2 — the highest HSPF2 rating available in a 4-ton Goodman heat pump. Unlike the Cold Climate "C" models at smaller tonnages, the GZV9SA4810 is the standard all-region configuration at 4-ton — delivering premium efficiency and inverter precision year-round for large homes across all US climate zones. The top-discharge design means conventional installation with no side-clearance concerns, while the variable-speed inverter compressor delivers the continuous, precise modulation that no two-stage or single-stage heat pump can match.
