Before you hire

A license is a floor, not a ceiling. Three quick checks cover most of what a license doesn’t guarantee:

Ask for a Certificate of Insurance (COI)
A current COI confirms the contractor carries general liability and, where applicable, workers’ comp. Licensing does not require insurance — ask for the certificate directly.
Match the name on the license to the person on site
License lookup verifies the license — not the person showing up. Confirm the worker’s government ID matches the name here.
Confirm a permit will be pulled (if the work requires one)
Most permit-required hvac work must be filed with the city before work begins. A contractor who wants to skip the permit is a red flag.

Permit portals (big-four Texas cities)

Outside the big four? Search “[your city] building permit” or call your local building department to confirm whether a permit is required.

This checklist is general guidance, not legal advice. Always review the contract and scope of work with the contractor before signing.

Get notified before your license expires.
