What are the recommended efficiency levels for heating and cooling equipment?
Heating and cooling equipment is rated according to industry standards for performance and efficiency. The higher the number, the more efficient the system. For cooling efficiency, look for the Seasonal Energy Efficiency Rating (SEER). All new heat pumps and air conditioners have a SEER rating of 10.0 or higher. We recommend a minimum SEER rating of 12.0. On the heating side, the Heating Seasonal Performance Factor (HSPF) is the measure of a heat pump’s heating efficiency. HSPF ratings range from 6.8 to 10.0 or higher. Look for models with at least a 7.0 rating. Gas furnaces are rated based upon their Annual Fuel Utilization Efficiency (AFUE). Look for an AFUE of at least 80 percent.
