Best HVAC Schools in Connecticut
If you want to work in heating, ventilation, air conditioning, and refrigeration (HVACR) in Connecticut, choosing the right school is your first step. Quality training will set you up for the licensing process, and it will also prepare you for everyday work in the field.
Here’s what you need to know to get started and where to find the best HVAC training programs in Connecticut.
HVAC licensing in Connecticut: what to know first
In Connecticut, most HVAC work requires a state license issued by the Department of Consumer Protection (DCP). This applies whether you work for yourself or for a contractor.
State licensing requires that you complete an approved apprenticeship or equivalent program and pass a trade exam.
The main license types for HVAC work include:
S-2: Unlimited Heating, Piping, and Cooling Journeyperson (requires apprenticeship)
D-2: Limited Warm Air, Air Conditioning Journeyperson
B-2: Limited Gas and Oil Burner Journeyperson
These categories depend on the type of systems you want to work on. Advanced licenses, like S-1, require more experience and lead to contractor-level work.
