Description
The Goodman GZV7SA is a 17.5 SEER2 inverter-driven split heat pump available in 2, 3, 3.5, 4, and 5-ton sizes, built in a compact side-discharge cabinet for properties with limited outdoor clearance. Across all sizes, the core technology is identical: a variable-speed swing compressor that continuously modulates capacity to match actual load, paired with a digitally commutated fan motor and proprietary algorithmic control logic.
The system runs longer at reduced capacity on mild days and scales up only when conditions demand it, delivering tighter temperature control and lower sound levels than single or two-stage alternatives, along with strong heating capacity to carry more of the home’s heating load before backup heat is needed. All GZV7SA models run R-32 refrigerant, which carries a lower global warming potential than R-410A and is becoming the standard for new high-efficiency residential equipment.
The three-level quiet mode brings operation as low as 45 dBA, and a field-selectable boost mode increases compressor speed during unusually high load conditions without any wiring changes. In communicating mode, only two low-voltage wires to the outdoor unit are required — a practical advantage on installs where additional control wiring is difficult to run. The unit also supports standard thermostat wiring for installs that don’t need communicating control, and is compatible with Goodman GTST or Daikin DTST connected thermostats and other Goodman communicating equipment.
The heavy-gauge galvanized steel cabinet uses a custom ivory white powder coat finish over a corrosion-resistant ZAM® unpainted steel bottom frame and legs, rated to 500-hour salt spray for coastal and humid environment durability. When properly anchored, all models meet 2023 Florida Building Code requirements for hurricane-type wind integrity. Anchor bracket kits available separately.
Service-friendly features are consistent across the line: sweat connection service valves with easy gauge port access, coil and ambient temperature sensors, a suction pressure transducer, a field-installed bi-flow filter drier, and a seven-segment LED display with fault code storage for fast diagnostics. AHRI Certified, ETL Listed. Made in USA.
