Goodman 4 Ton 17.2 SEER2 Two-Stage R-32 Heat Pump System | GLZT7CA4810 + AMVT Variable-Speed Air Handler

An AHRI-matched Goodman GLZT7 two-stage heat pump system: the GLZT7CA4810 4 ton R-32 outdoor heat pump paired with a Goodman AMVT variable-speed air handler. Two-stage operation runs on low stage most of the time, which means longer, quieter cycles, steadier temperatures, and better humidity control than a single-stage system.

FAQ What thermostat do I need?Use a thermostat that supports two-stage heat pump operation with auxiliary heat. Check the installation manual for compatible communicating thermostats if you want to use communicating mode.Why is the air handler a larger size than the outdoor unit?This pairing is the AHRI-certified match for this outdoor unit. The variable-speed blower adjusts airflow to the system, so the cabinet size is not a mismatch. Do I need a heat kit? Most heat pump installs include one for backup and defrost heat. Size it to the home's heat loss: smaller kits suit mild climates, larger kits colder ones. Can I reuse my existing line set? Sometimes. Size and condition must suit R-32 and this system's specs. Your installer should verify the line set and flush it if it's being reused. Is this compatible with my old R-410A or R-22 equipment? No. Replace both the outdoor unit and the indoor unit together with this matched R-32 system.
