What We Test, and What You Get Back

Every service below ends the same way: measured results, registered documentation, and a report the inspector accepts. Click below to determine what your specific project may need.

HERS Testing

HERS testing is the field verification California's Energy Code requires when permitted work touches HVAC, ducts, insulation or the building envelope. A certified rater measures what was actually installed and registers the results. If a system falls short, the contractor corrects it and we retest.

  • Diagnostic testing on the measures your permit triggers
  • Results registered with a HERS provider, not just written up
  • Retesting after corrections so the job closes out

Air Balancing

Air balancing measures and adjusts airflow so each room gets the volume it was designed for. It fixes the bedroom that never cools and the conference room that runs cold, and on multi-zone and commercial systems it is usually required before sign-off.

  • Airflow measured at every register and return
  • Dampers and fan settings adjusted to design CFM
  • Test & balance report showing design, actual and percentage

CF-2R & CF-3R Forms

CF-2R and CF-3R are the Title 24 certificates of installation and verification. The building department looks for them, and they have to match the equipment actually installed. We complete and register them as part of the testing.

  • Forms completed from measured results
  • Registered with the HERS provider your permit requires
  • Copies to you, the contractor and the homeowner

Duct Leakage Testing

Duct leakage testing pressurizes the duct system and measures how much air escapes. Leaky ducts waste the capacity you paid for, pull in attic air, and fail inspection. The test gives you a leakage percentage against the allowed rate, so there is no guessing.

  • Total leakage measured against the required rate
  • Full-system air loss calculated, across boots, registers, and grilles
  • Pass or fail documented for the permit file

Refrigerant Charge & Airflow

New and replacement air conditioning systems are verified for correct refrigerant charge and adequate airflow across the coil. Get either wrong and the system runs inefficiently, struggles in heat, and wears out early, and it will not pass verification.

  • Charge verified by the method your equipment calls for
  • System airflow measured, not estimated
  • Findings documented for Title 24 compliance

QII & Indoor Air Quality

Quality Insulation Installation verification happens while the walls are still open: insulation checked for gaps, compression and coverage before drywall. We also verify mechanical ventilation and the indoor air quality measures newer code requires.

  • Framing-stage and insulation-stage inspections
  • Gaps, voids and compression caught before drywall
  • Ventilation and indoor air quality verification
