Jmj Mechanical Services LLC

What this record tells you

Jmj Mechanical Services LLC holds Florida licence CMC1251786, 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 2026, which makes it one of the newer licences for the trade in this area. Roughly 95% of the 333 active hvac & ac repair licences based in the Melbourne & Space Coast area were issued earlier than this one, and the local median sits at 2013. That is 0 years of continuous licensure.

Jmj Mechanical Services LLC is one of 10 active hvac & ac repair licences registered to an address in Mims, 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.
