Goodman produces both heating and air conditioning systems. As of 2015, Goodman has six different series of central air conditioning systems. The Goodman DSXC18 is the company's most energy-efficient system with up to 18 SEER.
The Goodman DSXC18 split system air conditioner is available in three different models with cooling capacities of 35,000 BTU, 47,000 BTU and 57,000 BTU. The system uses R-410A chlorine-free refrigerant and is powered by a two-stage Copeland UltraTech scroll compressor. A high-density foam compressor blanket and super-quiet condenser fan limit noise from the system. The DSXC18 is compatible with the ComfortNet Communications System. Customers give this central air system 4.8 out of five possible stars. All Goodman air conditioning systems are protected by a 10-year parts warranty and a lifetime compressor warranty.
