HVAC: The D2 Program

Warm Air, A/C and Refrigeration.

According to the U.S. Bureau Of Labor Statistics, jobs in Heating, Air Conditioning, and Refrigeration are expected to grow by an impressive 21% through 2022. ENTECH’s D2 Program can prepare you to take advantage of that growing opportunity.

A CT D2 license will allow you to install, service, repair, maintain, and alter any warm air, A/C, or refrigeration systems. To qualify for a D2 license, you must complete 4,000 hours (2 years) on the job as part of the CT apprenticeship program. Apprenticeships are paid jobs that provide the necessary training to acquire your license. ENTECH provides all the necssary class instruction in about 6 months time.
