Goodman GSZC18 Specification

The Goodman GSZC18 is a high-efficiency, two-stage heat pump designed for residential applications, offering robust performance and energy savings. At its core, the GSZC18 utilizes a high-efficiency scroll compressor, providing reliable and quiet operation. This model is rated with a SEER (Seasonal Energy Efficiency Ratio) of up to 18 and an HSPF (Heating Seasonal Performance Factor) of up to 9.5, which ensures significant energy savings compared to older, less efficient models. It features a two-stage Copeland® UltraTech scroll compressor, which allows for optimal cooling and heating performance by operating at a lower stage during mild weather and ramping up during more extreme conditions. The SmartShift™ technology incorporated into the system ensures a reliable and quiet defrost cycle.

The heat pump is equipped with a factory-installed bi-flow liquid-line filter drier, which protects the system from moisture and debris, enhancing its longevity and performance. Enhanced durability is achieved through a heavy-gauge, galvanized steel enclosure with a powder-paint finish that provides superior protection against the elements. The ComfortBridge™ technology embedded in the GSZC18 continuously monitors system performance and adjusts settings for optimal efficiency and comfort. The unit is compatible with Goodman’s ComfortNet™ communicating control systems, offering advanced diagnostics and a range of customizable settings.

Furthermore, the GSZC18 supports environmentally friendly R-410A refrigerant, which does not contribute to ozone depletion. It is engineered for quiet operation, incorporating components such as a high-density foam compressor sound blanket and a wire fan discharge grille to minimize operational noise. These features make the Goodman GSZC18 a reliable and efficient choice for homeowners seeking year-round comfort and energy efficiency in their heating and cooling systems.
