Horizontal Discharge VS. Vertical Discharge

The side-discharge design of the YORK® HMCG2 is more efficient than traditional top-discharge designs in both size and operation. Snow and organic debris won’t hamper operation, and the sleek design results in 36% quieter operating volume and a 40% smaller footprint compared to standard heat pump units. With a setback distance of only eight inches, the HMCG2 is perfect for high-density areas, unlike traditional horizontal-discharge units, which often require at least 24 inches.
