What the contractor's bond covers
California requires most licensed contractors to carry a $25,000 contractor's bond. It can pay certain claims for license-law violations — it is not insurance for your project and is not a measure of work quality. The CSLB lists the surety and bond number.
About the prior disciplinary-bond record
A disciplinary bond is one the CSLB can require after a past issue. The record here shows a case that has since been cancelled — a closed, historical item, not a current action. The dates are on the official CSLB record.
What this record does and does not tell you
The California Contractors State License Board (CSLB) tracks license status, classification, bond, and workers'-comp. It does not rate work quality, track general-liability insurance, or collect customer reviews. Use it to confirm the license is real and in good standing, then check references and a written contract separately.
What classification C20 covers
CSLB #1006003 is classified Heating & Air Conditioning (C-20). A California contractor is licensed only for the classifications on record; work outside them may fall outside the license. The full classification list is on the official CSLB record.
