Precision Mechanical & Plumbing Inc holds Florida licence CMC1250344, 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 2013, which makes it a long-held licence for the trade in this area. Roughly 34% 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 13 years of continuous licensure.
Precision Mechanical & Plumbing 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. John Marino Hernandez additionally holds 4 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.
