Full Service HERS Testing

Everything You Need to Know About the HERS Program Home Energy Audit in Sacramento and Surrounding Areas

The Home Energy Rating System, or HERS program, is designed to test the energy efficiency of your home. In California, this program is designed to help find and prevent construction defects and faulty installation of HVAC systems and insulation before they become a major problem. Each HERS rater is trained and certified by the California Energy Commission. 

With the HERS program, faulty insulation and poor quality equipment can cause issues with heating, air conditioning and overall ventilation. If installed incorrectly or poorly, these HVAC systems can cause the average home to lose up to 30 percent of its conditioned air. In addition, when this happens the heat flow resistance from the equipment doesn't match the manufacturer's stated levels. These numbers are important to ensure compliance with state and local building codes, as well as to maintain comfort and air quality levels in the home. 

Why Hire a HERS Rater?

With new construction or HVAC replacement, the licensed contractor is required to seal the ducts of a home and test to check for air tightness. Once the ducts are sealed, a certified HERS rater will check and verify how much leakage is in the duct system and if it passes or fails the established levels. 

HERS testing measures a home's energy efficiency on a scale that goes from 0 to 250. It can also determine whether installed appliances meet energy efficiency requirements as designated statewide. Proper and professional HERS testing can take anywhere from 2-4 hours. 

Who Designed the HERS Program?

In order to measure the energy efficiency of homes, the HERS rating was developed by the Residential Energy Services Network or RESNET. The lower the number on the scale, the better the energy efficiency. The HERS system is used by the US Department of Energy, The Environmental Protection Agency and the U.S. Department of Housing and Urban Development as an official method to rank the energy efficiency of a home. 

What Does HERS Testing Involve? 

After proper HERS testing has been conducted on a home, the rating can tell the homeowners or contractor how their home ranks in terms of its energy efficiency. In short, a HERS rater will look at your overall HVAC system and run tests on vents and ductwork as well as check all exterior walls to determine the levels of air leakage in the home. 

Generally speaking, during a HERS test, a duct leakage test will be performed to see if there are any air leaks in any areas that the duct system feeds into. If you experience things like variable temperatures in a room (parts are warm while other parts are cold), it could indicate an air leakage issue. In addition, other things like verifying the levels of refrigerant in your air conditioning system to ensure that it is working at proper efficiency. A blower door test may be used to test the air pressure inside your home. 

When Should HERS Testing Be Done?

HERS tests are most commonly done when a home is bought, sold or built. If you're selling a home, having a HERS rating can help possible buyers understand its energy efficiency levels. It can also be used as a measure to help them understand the cost of future energy bills as well as whether or not any energy efficient upgrades will be needed. 

In addition, all homeowners in California as well as contractors are required to comply with the state's Code of Regulations (Title 24, Part 6) of the Energy Efficiency Standards for Residential and Nonresidential Buildings in order to meet the state's energy goals and abide by the requirements and regulations. 

You should also know that as a homeowner in California, you're required to schedule HERS testing if a new mechanical system (such as HVAC replacement) is installed in your home. Any such system that needs to be verified in this way needs to have a HERS test done in order to ensure compliance to the aforementioned code. This helps the Energy Commission to understand the difference in energy efficiency levels in home and to determine the best course of action for investing in energy efficiency expenditures.
