Cool World Inc

What this record tells you

Cool World Inc holds Florida licence CAC058565, 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 2001, which makes it one of the longest-held licences for the trade in this area. Roughly 16% 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 25 years of continuous licensure.

Cool World Inc is one of 94 active hvac & ac repair licences registered to an address in Lake Worth, so you have local alternatives to compare quotes against. Mark A O'Donnell 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 08/31/2026. 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.
