Product Features

Quiet Comfort
Goodman takes great pride in providing comfort that doesn't disrupt your home. The louvered top and three-bladed condenser fan of the GSZ130481 were designed to reduce noise levels without compromising performance. This model also has a high-capacity discharge muffler to curtail vibrational noise.

Filter Drier
A biflow filter drier is installed in the liquid line of this heat pump. It serves two important purposes: removing moisture and trapping impurities. This prevents corrosion, freezing, and blockages that can negatively impact the operation of the heat pump.

Secure Cabinet
The cabinet of the GSZ130481 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.

High-Efficiency Compressor
This unit utilizes a high-efficiency scroll compressor to provide refrigerant flow. Scroll compressors are renowned for operating more smoothly and reliably than traditional compressors.

Compressor Protection
Goodman installed two layers of compressor protection in the GSZ130481. A suction accumulator collects excess liquid refrigerant, preventing it from flooding and damaging the compressor during operation. A crankcase heater ensures that the compressor stays well-oiled by maintaining a compressor temperature that discourages oil migration.

Product Note

Compliance withUS Federal Regional Efficiency Standards is dependent on the rated efficiency of your entire system, not the nominal efficiencies of individual components. If you are unsure if your system will be compliant, please confirm before purchasing by calling us at 866-554-4328 or email us at
