How to check this licence yourself
Don't take our word for it — Alabama publishes this for free, and it takes about a minute:
- Search for Alabama Licensing Board for General Contractors (LBGC full roster export)'s own public contractor licence lookup — every state runs one.
- Search licence number S-48904, or the business name Mullican Air Systems Inc.
- Check the status reads active and the expiry is in the future — ours shows 4/30/2027.
- Ask to see proof of liability insurance too. State licensing does not cover that, and we cannot verify it.
A licence means the state has certified the holder to do this work. It is not a guarantee of workmanship, price or availability — see our contractor hiring checklist for what else to ask.
