Learn about HERS Testing

Updated: Apr 20, 2022

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.


Where can I find a HERS rater for my project?


To find a HERS Rater near you, please contact one of the approved HERS Providers shown below. Please note whether the Provider you are contacting is approved to perform the service you are seeking to contract. If you have any questions, please contact the Energy Standards Hotline.
