Supreme Construction & Development LLC

What this record tells you

Supreme Construction & Development LLC holds Florida licence CAC1822104, 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 2023, which makes it a relatively recent licence for the trade in this area. Roughly 73% of the 1,150 active hvac & ac repair licences based in the Orlando area were issued earlier than this one, and the local median sits at 2016. That is 3 years of continuous licensure.

Supreme Construction & Development LLC is one of 27 active hvac & ac repair licences registered to an address in Altamonte Springs, so you have local alternatives to compare quotes against. Yhonny Diaz 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.
