Duval Master Construction Inc

What this record tells you

Duval Master Construction Inc holds Florida licence CAC1821674, 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 2022, which makes it a relatively recent licence for the trade in this area. Roughly 73% of the 762 active hvac & ac repair licences based in the Jacksonville area were issued earlier than this one, and the local median sits at 2014. That is 4 years of continuous licensure.

Duval Master Construction Inc is one of 61 active hvac & ac repair licences registered to an address in Saint Augustine, so you have local alternatives to compare quotes against. Edward Heath Thomas additionally holds 14 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 08/31/2026. 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.
