If you’re building, remodeling, or selling a home in California, you may have heard of something called a HERS test. But what does that mean, and why do you need one? At 5 Star Energy, we provide fast, affordable, and accurate HERS testing to help homeowners, builders, and contractors meet California’s strict energy regulations. More importantly, we help make homes more efficient, more comfortable, and less costly to run.
In this article, we’ll explain what a HERS test is, when it’s needed, and why it’s an important part of owning or upgrading a home in California.
What Is a HERS Test?
HERS stands for Home Energy Rating System. A HERS test is an official inspection done by a specially trained and certified professional called a HERS rater. The test checks how energy efficient your home’s systems are, such as your heating, cooling, ductwork, and insulation.
Think of it like a “smog check” for your home. Just like your car needs to meet certain standards to be on the road, your home needs to meet California’s energy standards. These standards are known as Title 24, and the HERS test helps prove that your home meets them.
When Do You Need a HERS Test?
In California, a HERS test is required for many construction and remodeling projects. You may need a HERS test if you are:
- Installing or replacing a central air conditioner or furnace
- Changing or adding ductwork in your home
- Upgrading your HVAC (heating, ventilation, and air conditioning) system
- Building a new home or room addition
- Selling a newly constructed home
- Applying for energy rebates or tax credits
- Getting a Title 24 energy compliance report for a building permit
Even small upgrades to your HVAC system may require a HERS test to make sure everything meets code.
Types of HERS Tests
There are several different HERS tests. Depending on your project, you might need one or more of the following:
1. Duct Leakage Testing
This checks how much air escapes from your ductwork. If too much air leaks out, your system works harder and costs more to run. Leaky ducts can also lead to poor air quality and uneven heating or cooling.
2. Airflow Testing
We measure how much air is moving through your vents to make sure each room is getting the right amount of heating or cooling.
3. Refrigerant Charge Verification
This checks if your air conditioner has the correct amount of refrigerant. Too much or too little can reduce efficiency and cause damage.
4. Fan Watt Draw Testing
This test makes sure your HVAC fan is not using more energy than it should. Efficient fans save money and extend the life of your system.
5. Whole-House Energy Rating
This is a full evaluation of your home’s overall energy use. It’s often required for new homes and can help when applying for green building certifications.
At 5 Star Energy, we handle all types of HERS tests, so you’ll get exactly what you need for your project—nothing more, nothing less.
Why Is HERS Testing So Important?
✅ It Helps You Meet Code
Failing to get a HERS test when it’s required can lead to failed inspections, permit delays, or even fines. A certified HERS rater makes sure your project passes the first time.
✅ It Saves Energy (and Money)
HERS tests often uncover small problems that can cost you big money over time. Fixing leaks, improving airflow, and properly charging your AC unit can lower your energy bills and reduce strain on your system.
✅ It Makes Your Home More Comfortable
Balanced airflow, sealed ducts, and correctly functioning systems help maintain even temperatures in every room—no more hot or cold spots.
✅ It Increases Home Value
Buyers love energy-efficient homes. A good HERS rating makes your home more appealing and can even boost resale value.
✅ It Qualifies You for Rebates
California offers many energy rebate programs, but many require a passing HERS test first. Getting tested can help you earn back money for your upgrades.

Only certified professionals can perform a HERS inspection. These professionals are trained and approved by the California Energy Commission.

What Happens If You Fail a HERS Test?
Don’t worry—failing a HERS test doesn’t mean disaster. It just means something in your home isn’t meeting current energy standards.
