MPHinc. HERS Testing and Verification
HERS Verification Title 24, part 6

What is it: HERS stands for Home Energy Rating System. This process is a field verification and diagnostic testing service developed to
show compliance with the “California Building Energy Standards”.

Why it's important: A study conducted by National Comfort Institute shows that the average HVAC system is only performing at 58% efficiency. Don’t get lumped in with the national average. Prove the high quality and performance of your work with diagnostic testing.

HERS Inaccessible Leakage Verification

(smoke test) - Costa Mesa - Orange County

Inaccessible leakage is best understood with a smoke test - air leaks in a duct system are invisible. Pressurizing the duct system with a theatrical smoke machine can make these leaks visible and show whether or not the leakage sites are accessible for repair.

HERS Inaccessible Leakage Verification

When altering an existing HVAC system, there could be some mandatory 3rd party HERS tests and verifications, such as Duct Leakage Testing - Inaccessible Leakage Verification (smoke test).


When duct leakage testing is required, there is a maximum amount of leakage allowed unless the measured leakage is coming from an area that can’t be accessed without causing damage to the HVAC system or the structure.
