Harper Limbach LLC

What this record tells you

Harper Limbach LLC holds Florida licence CMC1250023, 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 2009, which makes it a long-held licence for the trade in this area. Roughly 31% of the 1,150 active hvac & ac repair licences based in the Orlando area were issued earlier than this one, and the local median sits at 2016. That is 17 years of continuous licensure.

Harper Limbach LLC is one of 18 active hvac & ac repair licences registered to an address in Lake Mary, so you have local alternatives to compare quotes against. Warren Roy Klemm 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.
