Making Sense of Energy Ratings

Under the terms of the National Appliance Energy Conservation Act (NAECA), energy-efficiency standards for residential cooling systems have been raised. A minimum of 13 SEER (Seasonal Energy Efficiency Rating) is required for air conditioners and 13 SEER/7.7 HSPF (Heating Seasonal Performance Factor) for heat pumps.

Equipment rated 13 SEER or higher costs more than 10- and 12-SEER systems. However, it’s important that you consider overall value. The improved energy efficiency of higher-SEER equipment will lower your utility bills, saving you money in the long run.
