A HERS test, or Home Energy Rating System test, assesses a home’s energy efficiency. The test is performed by a certified HERS rater and takes approximately two to four hours to complete, depending on the size of the home.
The first step of the HERS test is to evaluate the home’s energy usage by looking at past utility bills. The rater will then take measurements of the home’s insulation levels and window efficiency. They will also assess the heating and cooling systems, as well as the overall airtightness of the home. All of this information will be used to generate a HERS score, which is a number that represents the energy efficiency of the home on a scale of 0-100.
HERS tests are a great way to assess your home’s energy efficiency accurately. The test is quick and easy and can be performed by a certified HERS rater. A HERS test is a great place to start if you’re interested in making your home more energy-efficient!
