4d Mechanical LLC

What this record tells you

4d Mechanical LLC holds Florida licence CMC1249931, a CMC 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 2008, which makes it a long-held licence for the trade in this area. Roughly 30% of the 1,019 active hvac & ac repair licences based in the Tampa area were issued earlier than this one, and the local median sits at 2016. That is 18 years of continuous licensure.

4d Mechanical LLC is one of 66 active hvac & ac repair licences registered to an address in Plant City, so you have local alternatives to compare quotes against.

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.
