HVAC energy audit in Los Angeles
An energy audit is how you find out why your energy bills are high, whether your HVAC is sized correctly, and which upgrades will deliver the most savings per dollar. HVAC in LA performs residential HVAC energy assessments that go beyond a walkthrough — we measure, calculate, and document.
What we assess
- HVAC system performance — is your AC or heat pump operating at or near rated efficiency? We measure actual capacity, airflow, and COP vs nameplate data.
- Manual J load calculation — is your system the right size? Oversized systems short-cycle and never properly dehumidify. Undersized systems run constantly and still miss setpoint.
- Duct leakage test — what percentage of conditioned air is reaching your rooms vs leaking into the attic? Industry average is 25–30% leakage; it should be under 10%.
- Envelope assessment — insulation levels, window performance, infiltration. HVAC savings from a well-sealed, well-insulated home are often larger than equipment upgrades.
- Rebate eligibility — we identify which programs you qualify for and what improvements would increase your rebate eligibility.

HVAC Energy Audit FAQs
How much does an HVAC energy audit cost?
A basic HVAC performance assessment is $149–$299 and covers system capacity testing, airflow measurement, and a written report. A full Manual J + duct leakage test starts at $399. Audit fees are often credited toward qualifying upgrades.
Will an energy audit qualify me for rebates?
An energy assessment is required documentation for some HEEHRA and TECH Clean California projects. In some cases, the audit itself is rebate-eligible. We apply for every applicable program during the process.
My bills are high — where should I start?
Duct leakage is the most common culprit for high HVAC energy bills in LA homes. Losing 25% of conditioned air to attic leakage is equivalent to leaving a window open all summer. We test duct leakage on every energy audit.
Do you provide a written report?
Yes. Every energy audit includes a written report with measured data, identified inefficiencies, recommended upgrades ranked by cost-effectiveness, and rebate eligibility summary.
