Methodology
How every listing is checked, and how data gets refreshed.
California licenses HVAC contractors under classification C-20. The Contractors State License Board (CSLB) maintains a public registry that reports license status, bond filings, workers compensation coverage, and any formal complaints.
A scheduled job pulls the C-20 roster for Sacramento and the Central Valley once per month and regenerates the index. Listings whose license has expired, been suspended, or moved to inactive are dropped at the next build.
Rankings use fixed weights — distance, tenure, complaint count, bond, and urgency. The exact inputs are printed under every match.
The five checks
01
License class
Must be C-20. Not C-36, not C-38. HVAC specifically.
02
License status
Current and active. Expired, suspended, or canceled are excluded.
03
Bond
Active $25,000 contractor bond on file.
04
Workers compensation
Valid coverage, or CSLB-filed exemption.
05
Complaint record
Complaints on file are shown on the listing alongside the count.
Common questions
Do contractors pay to be listed?
No. The index is mirrored from the public CSLB registry. There is no paid tier and no paid placement.
Why no email capture?
The site doesn't collect contact info from visitors. Phone numbers and websites shown come from the contractor's CSLB record.
How is a contractor removed?
Automatically, at the next rebuild, if the license is no longer active. Contractors can also request removal by email.
What about reviews?
We don't host reviews. The site surfaces the complaint count from CSLB, which reflects filings on record.
Why these seven cities?
That's the footprint covered today. Expansion depends on data quality for the new regions.
Data freshness?
Each page shows a "Data as of" date reflecting the most recent build. A new build runs monthly.
