Thompson Plumbing Heating and Air Conditioning — Oceanside plumber profile
This profile is built from two public sources and nothing else: the company's California contractor-license record, checked against CSLB records on July 6, 2026, and its public Google review data, pulled June 20, 2026. Coastal SD Pros is an independent directory — we don't perform plumbing work, and a listing here is not an endorsement.
4.9
The CSLB record, field by field.
Every value below is quoted from the Contractors State License Board's public record for license #974400 as it appeared on July 6, 2026, with one plain-English line on what each field means to a homeowner.
- License number
- 974400
The company's unique ID at the Contractors State License Board. Anyone can look it up free at cslb.ca.gov — no account needed.
- Registered business name
- THOMPSON HEATING AND AIR CONDITIONING INC dba THOMPSON PLUMBING HEATING AND AIR CONDITIONING
The license is registered to THOMPSON HEATING AND AIR CONDITIONING INC, doing business as (DBA) Thompson Plumbing Heating and Air Conditioning. A DBA recorded on the state license is the normal, legal way a company operates under a second name — the name you see in marketing matches the DBA on file.
- Classification(s)
- C-20 Warm-Air Heating/Ventilating/AC · C-36 Plumbing
What the state licenses this company to contract for. C-36 is the plumbing classification; C-20 covers heating and air conditioning.
- License status
- "This license is current and active."
CSLB's own wording on the record. Current and active means the company can legally contract for this work in California today.
- Issue date
- June 28, 2012 — licensed since 2012
The year the board first issued this license. "Licensed since 2012" is a CSLB fact, not a company marketing claim.
- Expiration date
- July 31, 2028
California contractor licenses renew on a cycle. If you're reading this near or after that date, check the live record for the renewal.
- Contractor's bond
- On file
A state-required bond consumers can file claims against if a job goes wrong. The live CSLB record lists the bond company and amount.
- Workers' compensation
- Insured — Wesco Insurance Company, policy WWC3782375, through April 7, 2027
Covers injuries to the company's workers on your property, so an on-the-job injury doesn't become your homeowner's-insurance problem. Verify the policy is still current when you hire.
Checked against CSLB records July 6, 2026 — re-checked at each data refresh, not nightly. Verify the live record before you hire.

Coastal SD Pros is an independent directory and lead-referral service, not a licensed plumbing contractor, and does not perform plumbing work. This profile is compiled from public records (CSLB, checked July 6, 2026) and public Google business data (June 20, 2026); it is not an endorsement, and "license verified" describes the record check, never the company's quality. Sponsored placements are labeled paid advertising; none is currently sponsored. Verify licensing, insurance, and a written estimate before hiring.
