When Do You Need a HERS Test?

Frequently Asked Questions

How much does a HERS test cost? HERS testing costs vary based on the size and complexity of the home. Contact us at (530) 275-3350 for a free quote.

How long does a HERS inspection take? Most residential HERS inspections can be completed in 2-4 hours, depending on the number of systems being tested.

What’s the difference between Title 24 and HERS testing? Title 24 is the energy calculation done before construction to ensure your plans meet California’s energy code. HERS testing is the field verification done during and after construction to confirm the home was built according to those plans.
