At Last A/C & Heating Service Inc holds Florida licence CAC058415, 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 15% 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 25 years of continuous licensure.
At Last A/C & Heating Service 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. Jonathan Charles Weber 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.
