Told you need a “HERS test”? Here’s exactly what that means — and how we make it easy.
When you replace a furnace or air conditioner, add ductwork, or take on many remodels in California, the law requires an independent inspector to test the work before your city signs off. That test used to be called a HERS test; as of January 1, 2026 it’s officially called ECC — Energy Code Compliance — testing. Same requirement, new name. We schedule fast, explain everything before we start, and file all the paperwork your building department needs.
Independent, by law
We don’t work for your contractor — we verify their work. That independence is the whole point, and it protects you.
No surprises
Before testing starts you receive a Consumer Information Form explaining what we’ll test and your rights. At the end, a written report of results and costs.
Fast and tidy
Most residential visits take one to two hours. We confirm your window, do the work, and leave your home the way we found it.
What we test, in plain English
Duct leakage · Airflow and fan efficiency · Refrigerant charge · Whole-house air leakage (blower door) · Fresh-air ventilation · Insulation quality (QII)
