Higher efficiency means higher savings.

Affi nity™ heat pumps can provide double the effi ciency of older models. To use the map and chart, determine the SEER/HSPF of your current system. Then using the map, fi nd your zone.

Cross-reference your zone and SEER/HSPF in the table to determine your approximate operating cost. Take the difference between your current cost and that of a new, more effi cient Affi nity™ System to learn your estimated annual savings.

Affi nity™ Series products are available with environmentally friendly R-410A refrigerant. This “new generation” refrigerant releases heat more effi ciently while being safer for the ozone layer.

(Based on 2005 DOE national average price for electricity [0.0945/kwh]. Assuming the use of 36,000 BTU nominal capacity. Cooling based on Bin data. Operating cost based on 2,100 sq. ft. and occupancy of 4 people. Actual savings may vary.) Seasonal Energy Effi ciency Ratio (SEER) ia a measure of air-cooling effi ciency. Heating Season Performance Factor (HSPF) is a measure of air-heating effi ciency.
