What this record tells you

Turn-Key Mechanical Systems LLC holds Florida licence CMC1251222, 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 2023, which makes it a relatively recent licence for the trade in this area. Roughly 74% of the 505 active hvac & ac repair licences based in the Port St. Lucie & Treasure Coast area were issued earlier than this one, and the local median sits at 2017. That is 3 years of continuous licensure.

Turn-Key Mechanical Systems LLC is one of 52 active hvac & ac repair licences registered to an address in Port Saint Lucie, so you have local alternatives to compare quotes against. Dustin Scott Cramer 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.
