The Goodman® brand DSZC18 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 DSZC18 contains the two stage, high efficiency Copeland® UltraTech scroll compressor, which provides improved temperature and humidity control. This unit is designed for the consumer who desires superb comfort and quiet operation. All Goodman 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 Goodman for this heat pump, please click on the Accessories tab above. (Also, you can view Goodman's specifications sheets at the "Instructions and Brochures" tab above). In order to achieve the 18 SEER efficiency this heat pump must be installed with the manufacturer recommended evaporator coil, a 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 Goodman's spec sheet found under the "Instructions and Brochures" 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. Need help putting a complete heat pump system together? Use our easy System Selector and we’ll do it for you! If you are installing a heat pump with a backup heat source which will be a fuel furnace, you will need to install an electronic all fuel kit. This kit switches between the two heat sources as needed and prevents both the heat pump and backup heat from running at the same time. Alternatively, you can install the Honeywell VisionPro 8000 (TH8320U1008) thermostat which has the all-fuel kit functionality built into it already, in which case an external all fuel kit would not be needed. 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.
