S&r Engineering Group LLC

What this record tells you

S&r Engineering Group LLC holds Florida licence CMC1250997, 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 2022, which makes it a relatively recent licence for the trade in this area. Roughly 58% 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 4 years of continuous licensure.

S&r Engineering Group LLC is one of 56 active hvac & ac repair licences registered to an address in Doral, 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.
