What is HERS?
The Home Energy Rating System (HERS) Program addresses problems in insulation, installation, and poor quality equipment installation for heating, ventilation, and air-conditioning (HVAC) systems. Studies have shown that the heating and air-conditioning ducts in the average home leak 30 percent of the conditioned air in the system. Incorrectly installed insulation does not provide the resistance to heat flow listed on the label.
