Goodman GLZS4 Heat Pump Systems

The Goodman GLZS4 is Goodman's standard single-stage R-32 heat pump, paired here with an AHRI-matched AMST multi-position air handler (9-speed ECM blower, factory TXV). Systems are rated about 14.5–15.2 SEER2 and come in every size from 1.5 to 5 ton.

It's the best-value choice for mild and moderate climates, where cooling matters most and the heat pump only needs help on the coldest days. Add an optional 5, 8, or 10 kW HKTSN heat kit for backup heat.
