American Mechanical Solutions

What this record tells you

American Mechanical Solutions holds Florida licence CMC1249644, 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 2006, which makes it a long-held licence for the trade in this area. Roughly 41% of the 73 active hvac & ac repair licences based in the Key West & The Keys area were issued earlier than this one, and the local median sits at 2010. That is 20 years of continuous licensure.

American Mechanical Solutions is one of 24 active hvac & ac repair licences registered to an address in Key West, so you have local alternatives to compare quotes against. Christopher Channing Leiser 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 08/31/2026. 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.
