The Direct Comfort by Goodman® brand DC-GSZC180361 16 to 18 SEER Heat Pump uses the chlorine-free refrigerant R-410A and features energy efficiencies and operating sound levels that are among the best in the heating and cooling industry. The DC-GSZC180361 contains a High-efficiency two-stage scroll compressor, which provides improved temperature and humidity control. This unit is designed for the consumer who desires superb comfort and quiet operation.

All Direct Comfort by Goodman 16 to 18 SEER heat pumps must be installed with a bi-flow thermostatic expansion valve. This valve is installed in front of the indoor evaporator coil inline with the line set piping.

This heat pump requires an indoor air handler or evaporator coil as part of a complete system. What tonnage coil or air handler should you use? It depends on two factors about the outside portion of the heat pump system: 1) the tonnage, and 2) the efficiency rating (listed as "SEER"). Usually, high efficiency heat pumps are required to use a larger tonnage evaporator coil than the tonnage of the outside heat pump. (For example, a 2 ton heat pump might be paired with a 3 ton or 3.5 ton evaporator coil.) To find the specific coils or air handlers that are recommended by Direct Comfort by Goodman for this heat pump, please click on the Accessories tab below. 

In order to achieve the 18 SEER efficiency this heat pump must be installed with the manufacturer recommended evaporator coil, a Direct Comfort by Goodman variable speed furnace, variable speed air handler, or variable speed modular blower and thermostatic expansion valve (TXV). (See the Accessories tab above for most compatible products, or Direct Comfort by Goodman's spec sheet found under the Documents tab above to verify heat pump efficiency with particular equipment combinations.) An 18 SEER system will reduce your electric bill approximately 12% - 14% more than a 16 SEER system.

This is a communicating piece of equipment and to achieve full efficiency and functionality it must be paired with a Direct Comfort by Goodman communicating furnace, air handler, or modular blower with evaporator coil. If pairing this with an alternate indoor unit you must verify that the indoor unit is compatible with a 2 stage cooling system and you will need part 0130M00485 for the installation. 

If pairing this unit with a Direct Comfort by Goodman communicating indoor natural gas/lp furnace in a dual fuel installation all of the staging is done through the communication between the furnace and heat pump and no specialized thermostat is required. If pairing this with any other fossil fuel furnace you will need a dual fuel capable thermostat such as the Honeywell TH8321WF1001 or TH6320WF2003.

Please note that this heat pump comes pre-charged with R-410A liquid refrigerant and by Federal law cannot be released to the atmosphere. 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.
