Kilbourne Heating & Air Conditioning Inc holds Florida licence CAC043934, 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 1988, which makes it one of the longest-held licences for the trade in this area. Roughly 5% of the 821 active hvac & ac repair licences based in the West Palm Beach area were issued earlier than this one, and the local median sits at 2016. That is 38 years of continuous licensure.
Kilbourne Heating & Air Conditioning Inc is one of 45 active hvac & ac repair licences registered to an address in Delray Beach, 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.
