Chief Cornerstone Construction Company Incorporated

What this record tells you

Chief Cornerstone Construction Company Incorporated holds Florida licence CAC1816833, 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 2011, which makes it a long-held licence for the trade in this area. Roughly 49% of the 191 active hvac & ac repair licences based in the Tallahassee area were issued earlier than this one, and the local median sits at 2011. That is 15 years of continuous licensure.

Chief Cornerstone Construction Company Incorporated is one of 137 active hvac & ac repair licences registered to an address in Tallahassee, so you have local alternatives to compare quotes against. John David Thomas additionally holds 2 other active Florida licences in our records, which can indicate a contractor qualified across more than one trade or entity.

The licence is recorded as expiring on 08/31/2028. 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.
