HVAC: The S-2 Program.

In depth, and in demand.


The S Program is the most comprehensive curriculum we offer. Our day program allows you to graduate in just months and begin a paid apprenticeship.

A CT S2 heating and cooling license allows an HVAC technician to work on any type of heating, piping or cooling equipment. People who hold S licenses are in-demand and well-compensated. In fact, the S2 license is sometimes called "The Other 4-Year Degree."  

Most of your learning as an HVAC technician will occur on the job during your 4-year paid apprenticeship. The only schooling you'll need to be on your way is the program offered by ENTECH.
