D.L. Williams Heating & Cooling, LLC

What this record tells you

D.L. Williams Heating & Cooling, LLC holds Florida licence CAC1816913, 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 2011, which makes it a long-held licence for the trade in this area. Roughly 41% of the 188 active hvac & ac repair licences based in the Gainesville area were issued earlier than this one, and the local median sits at 2014. That is 15 years of continuous licensure.

D.L. Williams Heating & Cooling, LLC is one of 21 active hvac & ac repair licences registered to an address in Lake City, 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.
