A-1 Service LLC

What this record tells you

A-1 Service LLC holds Florida licence CAC1813483, 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 2003, which makes it a long-held licence for the trade in this area. Roughly 26% of the 191 active hvac & ac repair licences based in the Tallahassee area were issued earlier than this one, and the local median sits at 2011. That is 23 years of continuous licensure.

A-1 Service LLC is one of 137 active hvac & ac repair licences registered to an address in Tallahassee, so you have local alternatives to compare quotes against. Yichun Han additionally holds 1 other active Florida licence 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.
