Grau Mechanical Enterprises Inc

What this record tells you

Grau Mechanical Enterprises Inc holds Florida licence CMC049229, 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 1989, which makes it one of the longest-held licences for the trade in this area. Roughly 7% of the 762 active hvac & ac repair licences based in the Jacksonville area were issued earlier than this one, and the local median sits at 2014. That is 37 years of continuous licensure.

Grau Mechanical Enterprises Inc is one of 430 active hvac & ac repair licences registered to an address in Jacksonville, 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.
