Our HERS Verification Services

Find the exact service you need for your HVAC, remodel, or new construction project.

Duct Leakage Testing

This essential HERS test is required for most Orange County HVAC permits, including new installs and change-outs. We use a calibrated duct blaster to precisely measure your system's airtightness, ensuring you pass your Title 24 inspection while preventing energy loss. A passing test confirms your ductwork is sealed tight for maximum efficiency and home comfort.

Blower Door Testing

Mandatory for all new construction homes in California, a blower door test measures the overall airtightness of your building envelope. Our certified test provides builders and contractors with the official verification needed to meet Title 24 energy code and finalize project permits. It's the ultimate proof of a high-performance, energy-efficient build.

Refrigerant Charge & Airflow

An improperly charged A/C unit wastes energy and shortens its lifespan. Our refrigerant charge and airflow verification confirms your system is operating at peak efficiency, as required by Title 24 for all new air conditioner installations. This test ensures you get the performance you paid for and helps you pass your HVAC inspection.

Fan Watt Draw

This technical HERS test measures the electrical consumption of your HVAC system's fan motor to ensure it meets California's strict energy standards. As a required part of the Title 24 verification process, our precise fan watt draw measurement provides the data needed to get your permit signed off. It's a critical check for modern, high-efficiency air handlers.

HVAC Compliance Package

This is the simplest, all-in-one solution for passing your HVAC permit inspection in Orange County. Our package bundles the three most common required tests—Duct Leakage, Refrigerant Charge, and Fan Watt Draw—into one efficient and cost-effective appointment. It's the fastest and most reliable way to get your permit finalized without any hassle.

Insulation & Envelope Verification

A critical quality assurance step for new construction, this HERS verification confirms your home was built to its energy design specifications. We visually inspect insulation installation, window ratings, and other building envelope components to ensure they align with your Title 24 report. This verification is mandatory for closing out new home permits.

Your Service Questions Answered

  • What's the difference between a Duct Leakage Test and a Blower Door Test?

    A Duct Leakage Test measures air leaks in your HVAC duct system only. A Blower Door Test measures total house leakage through walls, windows, ceilings, and more.

  • Which HERS tests do I need for a simple A/C replacement?

    Typically you’ll need three: Duct Leakage, Refrigerant Charge Verification, and Fan Watt Draw. Our Full Compliance Package covers them all.

  • How should I prepare my home for a HERS test?

    Provide clear access to HVAC equipment, condenser, and registers. For blower door tests, ensure all windows and exterior doors are closed. We send a prep checklist in advance.

  • How quickly will I get my compliance documents after the test?

    You’ll receive same-day CF3R forms upon completion, sent directly to you, your contractor, and the registry for permit closure without delay.
