The Goodman® GSX14 14 SEER Central Air Conditioner uses the environmentally friendly refrigerant R-410A and features operating sound levels that are among the best in the heating and air conditioning industry. R-410A is chlorine-free to help prevent damage to the ozone layer. The GSX14 central air conditioner features a high-efficiency Copeland® scroll compressor and is designed for the consumer who desires superior comfort, quiet operation, and environmentally friendly cooling performance.

This central air unit can be 14 or 15 SEER depending on which indoor unit it is paired with. If it is installed with the manufacturer-recommended evaporator coil, variable speed furnace, variable speed air handler, or variable speed modular blower, and also sometimes a thermostatic expansion valve (TXV), it is a 15 SEER system (see Accessories tab above for actual products compatible with this central air conditioner, or the Documents tab above for Goodman's spec sheet details). A 15 SEER central air conditioning system will reduce your electric bill approximately 7% more than a 14 SEER system.

Some models of the Goodman condensers include an orifice (also called "flow rater" or "piston") in a small bag taped to the side of the condenser. If the condenser you purchase includes this orifice, you will need to replace the orifice already inside the evaporator coil or air handler you purchase with this orifice included with the condenser. Doing so makes the condenser and evaporator coil compatible. You can viewthis step-by-step guide to see how to easily change the orifice.

Please note that this equipment comes precharged with R-410A liquid refrigerant, and by Federal law cannot be released to the atmosphere. You can purchase this equipment without being certified, and if you are mechanically inclined you can perform about 90% of the equipment installation yourself. However, you must have a professional heating/cooling contractor do the final part of the installation which requires managing the refrigerant.
