Southern Cross Building Solutions Inc holds Florida licence CAC056740, 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 1993, which makes it one of the longest-held licences for the trade in this area. Roughly 7% 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 33 years of continuous licensure.
Southern Cross Building Solutions 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. Marshall Brett Harris 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 08/31/2028. 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.
