Goodman established itself as the largest HVAC manufacturer in the US by producing high-quality, efficient equipment for homeowners at a great value. The GSZC18 heat pump is an incredibly efficient heating and cooling solution. With a SEER rating of 18 and an HSPF rating up to 10.0, you can count on low energy usage regardless of the application. The savings don’t stop at energy costs though; the GSZC180241’s design reduces installation and service times. It features a two-stage compressor to ensure steady comfort and includes advanced components that protect the coil and compressor for peace of mind and reliable operations.

Quiet Comfort

The wire fan discharge grille and condenser fan motor of the GSZC180241 were designed to reduce noise levels without compromising performance. A discharge muffler and a foam sound blanket reduce vibrational and compressor noise, respectively.

Filter Drier

A biflow filter drier is installed in the liquid line of this heat pump. The filter drier removes moisture and traps impurities, preventing corrosion, freezing, and blockages that can negatively impact the operation of the heat pump.

Secure Cabinet

The cabinet of the GSZC180241 is built to last. Galvanized steel construction, a durable powder paint finish, rust-resistant screws, and a steel coil guard protect your equipment from wear and tear, increasing its longevity.


Goodman’s SmartShift technology, combined with ambient and coil temperature sensors, gives this unit a quiet and effective defrost system. SmartShift also helps to prevent short-cycling, increasing the efficiency of defrost operations.

UltraTech Compressor

A two-stage Copeland UltraTech scroll compressor provides the GSZC180241 with incredibly reliable refrigerant flow. The second stage increases efficiency by allowing the compressor to operate at a lower capacity when your demand is low.

Compressor Protection

Goodman installed two layers of compressor protection in the GSZC180241. A suction accumulator collects excess refrigerant, while a crankcase heater ensures that the compressor stays well-oiled by maintaining a temperature that limits oil migration.


The included ComfortAlert compressor diagnostics module reduces the average time of maintenance calls and virtually eliminates misdiagnoses by experienced technicians, saving you money throughout the life of the heat pump.

ComfortBridge Compatible

This heat pump is compatible with Goodman’s ComfortBridge communicating controls. A ComfortBridge control shortens the installation and maintenance processes further by automatically detecting your equipment and providing diagnostics and troubleshooting.

Extended Warranty

Goodman offers a 10-year limited parts warranty when you register your product online within 60 days of installation. An unregistered product has the standard 5-year warranty. See warranty sheet under the “Manuals” tab for more information.

Product Note

The recommended line set size for this unit will vary based on the length of line set you require for installation. Compatible line sets can be found under the “Recommended Accessories” tab. | The US Department of Energy regulates minimum efficiency standards for central air conditioners and heat pumps based on geographic regions. We are required to abide by these regulations when selling products, and take this responsibility seriously. The standards depend on the rated efficiency of the entire system, not the nominal efficiencies of individual components. If you are unsure if your system will be compliant, please call or email us for help.
