Mississippi HVAC License Lookup

Whether you're a homeowner vetting a contractor before signing a proposal, a general contractor auditing subcontractors for compliance, or a technician checking your own license status before renewal — the Mississippi State Board of Contractors (MSBOC) maintains a public contractor database you can search online.

Here's how to use it and what to watch for.

Where to Search

The MSBOC contractor search is available at msboc.us. The database lets you search by contractor name, business name, or license number. Results show the license classification, the business entity on record, and whether the credential is currently active.

What the Search Tells You

A valid MSBOC lookup confirms several things:

• License classification — whether the contractor holds a Residential HVAC, Commercial HVAC Specialty, or Major Mechanical classification. This determines what scope of work they're legally authorized to perform.
• Active status — whether the license is current, expired, or suspended. A contractor whose insurance lapses gets an immediate license suspension, so "active" status means their CGL coverage and (if applicable) workers' compensation policy are current.
• Business entity — the legal name of the company holding the license. Under Mississippi contractor law, all documents — insurance policies, local permits, bank references — must match this exact business name.

What It Doesn't Tell You

The MSBOC database verifies state-level licensure only. It does not show:

• Municipal registrations. Even a fully licensed state contractor must register separately in cities like Jackson, Gulfport, Tupelo, Ridgeland, or Southaven before pulling local permits. The MSBOC search won't confirm whether a contractor has active local registrations.
• EPA Section 608 certification. Federal refrigerant handling credentials are issued by EPA-approved testing organizations, not the state board. There is no centralized public lookup for Section 608 certifications.
• Local bond status. Municipal surety bonds are filed with city building departments, not the state board. For example, Tupelo requires a $10,000 bond in the qualifying individual's name, while Jackson relies on state licensure verification and requires no local license or permit bond.
• Insurance policy details. The board knows if the policy is active (because they're listed as the certificate holder and receive lapse notifications), but the database doesn't display coverage amounts or policy numbers.

Why License Verification Matters

Under Mississippi law, the consequences of hiring or working as an unlicensed contractor are severe on both sides:

For the contractor: Mississippi Code Annotated § 73-59 prohibits unlicensed contractors from collecting profits. If a payment dispute goes to court, an unlicensed contractor can only recover actual documented expenses — no profit margin — and must prove those expenses by clear and convincing evidence.

For the property owner: Knowingly contracting with an unlicensed professional exposes the owner to civil penalties of up to 3% of the total contract value.

For general contractors: Under House Bill 1163, all subcontractors performing HVAC work on residential construction or improvement projects must hold an active MSBOC license, regardless of the subcontract's dollar value. A GC who fails to verify downstream licensure risks losing their own lien rights and facing board action.

Checking Your Own License Status

If you're a licensed contractor, the MSBOC database is also your quickest way to confirm your license hasn't lapsed due to an insurance hiccup or a missed renewal. Starting in 2026, the board sends renewal notices by email only — no more paper mail. If your contact information is outdated, you might not get the notice, and a lapsed renewal can cascade into a suspended license.

Commercial licenses renew for $200 annually. Residential licenses renew for $50 annually, plus 2 hours of approved continuing education for licenses issued on or after July 1, 2015. The database reflects current status, so a quick search after your renewal period confirms everything processed correctly.

The Bigger Verification Picture

State license lookup is one layer of a three-layer verification process. For a complete picture of whether a contractor is fully authorized to work at a specific job site, you'd also need to confirm their municipal registration and local bond status through the city building department, and verify their EPA Section 608 certification directly.

The Mississippi HVAC License Guide covers the full verification chain across federal, state, and municipal layers — including which cities require local bonds and what documentation to request from a contractor before signing a contract.
