Darnell Air Conditioning and Heating

What this record tells you

Darnell Air Conditioning and Heating holds Florida licence CAC1815375, 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 2007, which makes it a long-held licence for the trade in this area. Roughly 32% of the 762 active hvac & ac repair licences based in the Jacksonville area were issued earlier than this one, and the local median sits at 2014. That is 19 years of continuous licensure.

Darnell Air Conditioning and Heating is one of 32 active hvac & ac repair licences registered to an address in Middleburg, so you have local alternatives to compare quotes against.

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.
