About Pacific Airflow

Pacific Airflow is a certified ECC and HERS testing company serving builders, HVAC contractors, insulation crews, and developers across Northern California.

We specialize in energy code field verification for residential, multifamily, and light commercial projects, helping projects pass inspection quickly, cleanly, and without delays.

Under the new 2025 California Energy Code, energy verification is more detailed, more documented, and more strictly audited than ever before. Our job is to make sure your project meets code the first time.

We are known for fast turnaround, clear communication, and understanding how jobsites actually work.

Specialists in Multifamily and Large Projects

While we perform ECC / HERS testing on single-family homes throughout Northern California, we specialize in multifamily construction, where coordination, timing, and accuracy are critical.

From small developments to large apartment and townhome complexes, we understand how to keep multi-unit projects moving without creating inspection bottlenecks.

When you work with Pacific Airflow, you’re not just hiring a rater — you’re bringing on a partner who understands how to keep projects on schedule.
