Keller Mechanical and Engineering Inc

What this record tells you

Keller Mechanical and Engineering Inc holds Florida licence CMC013454, a CMC 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 1979, which makes it one of the longest-held licences for the trade in this area. Roughly 0% of the 330 active hvac & ac repair licences based in the Lakeland & Winter Haven area were issued earlier than this one, and the local median sits at 2017. That is 47 years of continuous licensure.

Keller Mechanical and Engineering Inc is one of 150 active hvac & ac repair licences registered to an address in Lakeland, 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.
