Diaz Mechanical LLC

What this record tells you

Diaz Mechanical LLC holds Florida licence CAC1819219, a CAC 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 2017, which makes it an established licence for the trade in this area. Roughly 52% of the 709 active hvac & ac repair licences based in the St. Petersburg & Clearwater area were issued earlier than this one, and the local median sits at 2015. That is 9 years of continuous licensure.

Diaz Mechanical LLC is one of 20 active hvac & ac repair licences registered to an address in Saint Petersburg, 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.
