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.
Manfred Construction Services, Inc. is one of 28 active hvac & ac repair licences registered to an address in Oldsmar, so you have local alternatives to compare quotes against. Manfred Gross 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.
