Thermal Line Inc

What this record tells you

Thermal Line Inc holds Florida licence CMC1250054, 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 2010, which makes it a long-held licence for the trade in this area. Roughly 28% of the 1,534 active hvac & ac repair licences based in the Miami area were issued earlier than this one, and the local median sits at 2019. That is 16 years of continuous licensure.

Thermal Line Inc is one of 921 active hvac & ac repair licences registered to an address in Miami, 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.
