Whether you’re purchasing, selling, or simply trying to reduce your home’s energy costs, adopting energy-efficient practices is great for the environment and your wallet. You can reduce your energy consumption in a number of ways, from getting a new HVAC system to installing a low-flow showerhead. Getting a rating from the Home Energy Rating System is a great first step to understanding your home’s energy consumption and identifying effective fixes. Keep reading to learn more about HERS testing, when you should get your home rated, how much it costs, and the benefits it provides.

HERS is an index for calculating how energy efficient a home is. The Residential Energy Services Network originally launched this index in 2006, but since then it has become the industry standard for evaluating a house’s overall energy performance. HERS testing is generally conducted on new or recently renovated homes, particularly when a builder is expected to satisfy certain efficiency standards. Some other instances when HERS scores are beneficial include:
When a rater comes to your home for HERS testing, they look for certain energy leaks or “bugs” in the crawl space, attic, foundation, thermostat, water heating system, ceiling, and wall insulation. In these spots, they’re looking for things like:
A HERS rating is the score given to a home to represent its overall efficiency. When assessing a home, HERS raters perform an inspection and enter the data into specialized software. From there, they are able to assign the home a HERS score from a scale of 0 to 150. With HERS, the lower the score, the more energy-efficient the home, and every one-point fluctuation represents a shift in the property’s energy efficiency by 1%.
In order to ensure that the score is accurate and relative to the size and type of house you live in, the rater compares your home to an analysis tool with a standard reference home. In the tool, the reference home is a designed model home that resembles the rated home’s climate, environment, shape, and size, meaning HERS scores are relative to the location and type of house you live in.
For a home to get a net-zero score, it means that the house produces as much energy as it uses. Most homes aren’t quite this efficient. In fact, the average HERS score is 100 for newly built, uninhabited homes, while lived-in houses usually get a HERS score of around 130. When you’re getting your home tested, a good score is considered anything at or below the average. If your score is a bit higher than the average score, that is an indication that your house needs a few upgrades or fixes.
Aside from providing a score, the HERS rating process gives homeowners important information, like:
Getting a home inspected by a certified RESNET Rater usually costs somewhere between $1,500 and $3,000. Though it can seem like a costly initial investment, identifying and making improvements to achieve a good HERS score can save homeowners significantly more on their utility bills. According to the RESNET HERS Index, cooling, heating, and water heating are among the most expensive aspects of homeownership, aside from a mortgage.
HERS testing is also the first step to getting your home eligible for an ENERGY STAR certification, which can save you a ton in energy costs. Additionally, you could be eligible to claim an energy-efficient home tax credit.
Regardless of whether you decide to get your house HERS-rated, you can make your home more energy-efficient by addressing these areas:
