Weatherproofing Technologies, Inc.

What this record tells you

Weatherproofing Technologies, Inc. holds Florida licence CAC1822440, 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 2023, which makes it a relatively recent licence for the trade in this area. Roughly 75% of the 709 active hvac & ac repair licences based in the St. Petersburg & Clearwater area were issued earlier than this one, and the local median sits at 2015. That is 3 years of continuous licensure.

Weatherproofing Technologies, Inc. is one of 73 active hvac & ac repair licences registered to an address in Largo, so you have local alternatives to compare quotes against. Robert James Mulcahy additionally holds 2 other active Florida licences 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.
