License check
How to Verify a Louisiana HVAC Contractor License
Look the company up in the Louisiana State Licensing Board for Contractors (LSLBC) Contractor Search, then ask about its city registration. State law defines a mechanical contractor by projects of “ten thousand dollars or more” ($10,000), and Shreveport and Bossier City each register air conditioning contractors on top of that. Checked against the statute and the cities’ pages on November 11, 2026.

The five-step check
- Ask for the license number and the exact business name. Ask the company for its Louisiana contractor license number and the legal name the license is under. A company that holds one will give it without hesitation.
- Open the LSLBC contractor search. Go to the Louisiana State Licensing Board for Contractors website and open Contractor Search. The search accepts a name, a license number, a city, a parish, a license type or a qualifying party.
- Search by license number first. Start with the license number. If you only have the name, search the name and pick the record whose city matches the company you are dealing with.
- Match the record to the company. Check that the name on the record is the name on the estimate, that the license is current, and that the classification covers mechanical work such as air conditioning and heating.
- Ask about city registration. Shreveport and Bossier City each register air conditioning and heating contractors. Ask which registration the company holds for your address, then confirm with the city permit office if in doubt.
Three layers: state, Shreveport, Bossier City
| Layer | What it says |
|---|---|
| State of Louisiana (LSLBC) | The statute defines a mechanical contractor by air conditioning, refrigeration and heating work “for which the project value is ten thousand dollars or more” ($10,000). |
| City of Shreveport | Anyone performing air conditioning or heating work in the city must have a contractor’s registration. The city says HVAC contractors doing work that exceeds $10,000 must hold a state master license. |
| Bossier City | Anyone performing air conditioning or heating work must hold a current Bossier City registration: apprentice $15, journeyman $30, master mechanical $150. |
The statute reads “ten thousand dollars or more”. The City of Shreveport’s page and the licensing board’s own summary word it as work exceeding that amount. For a job priced at or near the line, ask the licensing board.
What a license check does not tell you
- It does not tell you the price is fair. Compare the quote with the repair cost ranges.
- It does not confirm a permit was pulled. See the permit guide for when one is needed.
- It does not cover insurance. Ask for a certificate of general liability insurance for larger jobs.
Sources and dates
Every figure and rule above names where it came from and the date it was read. If a source disagrees with a quote you receive, the quote wins: it reflects your house, your equipment and this week's demand. Prices are rechecked at least every six months.
