How to get a HVAC contractor license in Florida

air conditioning contractor

Licensed air conditioning contractors are always in high demand in the state of Florida.  After all, it is called the Sunshine State for a reason.  Like many things, there are several types of air conditioning contractor licenses that can be achieved.  In this article we will dive into the differences between them so that if you are considering becoming licensed, you set your path towards the proper license for the type of work that you want to be able to do.  


Common Florida A/C contractor license types:

The most popular air conditioning contractor license categories are A/C – Mechanical, A/C-(A), and AC-(B).  The distinction between them comes down to the size and types of air conditioning units a licensee can install and service. 


  • Mechanical A/C – qualified to work on medical gas, fuel gas, and A/C units over 25 tons cooling.
  • A/C – (A) Contractor – qualified to work on units over 25 tons cooling, and over 500,000 BTU heating.
  • A/C- (B) Contractor – qualified to work on units up to 25 tons cooling, and up to 500,000 BTU heating.


Based on the above, you can probably guess that the highest certification of the three is a licensed Mechanical A/C contractor which allows for expanded work on the largest units, coolers, boilers, and the surrounding components such as the plumbing and ducting needed to allow them to operate.    


The A/C – (A) and AC – (B) licenses are the most common and still allow for a substantial amount of commercial as well as residential air conditioning work. However, it is important to note the size and specifications of the units as the proper license must be held based on the cooling tons and heating units. As far as achieving your (A) or (B) license is concerned, the only difference is a longer and more intensive trade knowledge portion of the state exam for anyone achieving their class (A) vs a class (B) license.
