Dynamic Testing & Design, Inc.

What this record tells you

Dynamic Testing & Design, Inc. holds Florida licence CAC1813617, a CAC classification which authorises work as a certified/registered air conditioning or mechanical contractor. A "C" prefix means the licence is certified — valid anywhere in Florida.

This licence was first issued in 2003, which makes it a long-held licence for the trade in this area. Roughly 14% of the 147 active hvac & ac repair licences based in the Panama City area were issued earlier than this one, and the local median sits at 2017. That is 23 years of continuous licensure.

Dynamic Testing & Design, Inc. is one of 2 active hvac & ac repair licences registered to an address in Port Saint Joe, so you have local alternatives to compare quotes against. Johnny Martin additionally holds 1 other active Florida licence in our records, which can indicate a contractor qualified across more than one trade or entity.

The licence is recorded as expiring on 08/31/2026. Florida licences renew on a fixed cycle, and a licence that is not renewed moves to delinquent status — which is why the expiry date matters if you are planning work close to that date. Confirm the current status on the state portal before signing a contract.
