If you're building a new home, upgrading your HVAC, or just want to breathe easier indoors, a HERS rating is your ticket to energy efficiency and cleaner air. But not all raters are created equal. I've dug into the Greater
Why HERS Ratings Matter More Than Ever
The Home Energy Rating System (HERS) is the gold standard for measuring a home's energy performance. In California, Title 24 energy code compliance often requires a HERS rating, especially for new construction and major HVAC upgrades. Duct leakage testing is a key component — leaky ducts can waste up to 30% of your heating and cooling energy. Beyond compliance, a good HERS score can lower your utility bills, improve indoor air quality, and increase your home's resale value. Sacramento's hot summers and cool winters make energy efficiency a top priority for homeowners and builders alike.
How I Ranked These HERS Raters
I evaluated each company based on five factors: service breadth (do they offer duct testing, Title 24, blower door, etc.?), geographic coverage (how many Sacramento-area cities do they serve?), turnaround time (same-day reporting is a big plus), online presence and transparency (clear pricing, service pages, and customer reviews), and certifications (CEC, BPI, etc.). Local expertise and years in business also played a role. All five companies are legitimate, licensed, and active in the Sacramento market.
Here's a quick look at the top five HERS raters in Sacramento. Each one brings something different to the table, so read on to find the best fit for your project.

How to Choose the Right HERS Rater for Your Project
Start by identifying your specific needs: are you a homeowner needing a simple duct leakage test, or a builder requiring full Title 24 compliance? Look for a rater that offers same-day or next-day reporting — delays can hold up your project. Check their service area to ensure they cover your city or county. Ask about certifications: CEC-certified technicians are a must for California compliance. Finally, read reviews or ask for references. A good rater will explain the process clearly and help you understand your HERS score.
Automate Your HERS Testing Workflow
Streamline the process from booking to results. First, use an online scheduling tool on the rater's website to book your test at a time that works for you. Many raters, like Poppy Energy and Express Duct Test, offer same-day appointments. Second, prepare your home or building by ensuring all vents are accessible and the HVAC system is operational. Third, the rater performs the test using a blower door and duct pressure equipment — this usually takes 1-2 hours. Fourth, receive your report digitally via email, often the same day. Finally, use the report to apply for rebates or make efficiency upgrades. Automating reminders and follow-ups can save you time and ensure nothing falls through the cracks.
