The Goodman 15.2 SEER2 GSZH5 Heat Pump is a highly efficient heat pump designed to the 2023 and beyond SEER2 standards. This unit will help reduce energy consumption throughout the life of the system for both heating and cooling and operates at a reduced sound level relative to the GSZ16 series it replaces. If you have an all electric heating system and aren't currently using a heat pump then you could easily save 30-50% on your heating bills if you switch to a heat pump system. If you are using fossil fuels for heat such as propane or fuel oil, replacing your AC system with a heat pump can, in most cases, greatly reduce your heating bills. 


In order to achieve the full efficiency and maximize it's performance this unit must be paired with the proper air handler, modular blower and evaporator coil, or furnace and evaporator coil.


Heat pumps such as the GSZH5 require a backup heat source for extreme cold temperatures. If you will be using a gas, LP, or oil furnace as a backup heat source, you will need to install a heat pump compatible thermostat that can switch between the two heat sources as needed and prevent both the heat pump and backup heat from running at the same time.

Please note that this heat pump equipment comes pre-charged with R-410A liquid refrigerant and by Federal law cannot be released to the atmosphere. Yes, you can purchase this equipment without being EPA certified, and if you are mechanically inclined you may perform about 90% of the equipment installation yourself. However, we strongly recommend to have a professional heating/cooling contractor do the final part of the installation including managing the refrigerant. An HVAC contractor has the tools and know-how to do this work. Also, having a contractor perform the final startup and inspection of this heat pump validates your warranty with Alpine.
