Is a Goodman GSX a heat pump?

Is a Goodman GSX a heat pump, no, Goodman GSX is not a heat pump, it is an air conditioner straight cool condenser, while Goodman GSZ is heat pump. Goodman model naming: GSX stands for Goodman Straight cooling Condenser with R-410A refrigerant and X for 14 SEER, for example GSX14 14 SEER single stage AC costs 3,000 to 5,000 dollars installed for 3-ton, includes outdoor condenser only that provides cooling only, must be paired with furnace like GMSS92 for heating. GSXC stands for Goodman Straight cooling Condenser with Communicating capability, for example GSXC16 16 SEER two-stage AC, also AC only. GSZ stands for Goodman Straight heat pump with R-410A, for example GSZ14 14 SEER heat pump costs 3,500 to 5,500 dollars installed for 3-ton, provides both cooling and heating by reversing refrigerant flow, must be paired with air handler like ARUF. GSZC stands for Goodman Straight heat pump with Communicating. So GSX is AC, GSZ is heat pump. To tell if heat pump, look at model number on rating plate: if contains Z, it is heat pump, if contains X, it is AC. Also heat pump has reversing valve inside that makes whooshing sound when switching modes. If you have GSX14 installed and want heating, you need furnace, GSX alone cannot heat. Always check indoor unit: AC paired with furnace has gas line, heat pump paired with air handler has electric strips.
