John Charles Renna

What this record tells you

John Charles Renna holds Florida licence CAC1813940, 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 2004, which makes it a long-held licence for the trade in this area. Roughly 19% of the 330 active hvac & ac repair licences based in the Lakeland & Winter Haven area were issued earlier than this one, and the local median sits at 2017. That is 22 years of continuous licensure.

John Charles Renna is one of 150 active hvac & ac repair licences registered to an address in Lakeland, so you have local alternatives to compare quotes against.

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.
