The next generation of HVACR technicians. That’s you.

HVACR careers offer excitement, security, and true growth potential. At Entech, you could go from learning to earning in just a few months!

Our program is your first step toward a secure, well-paying future. Entech offers a direct path into the Department of Labor's apprenticeship program. From there, you’ll be able to start gaining the experience you'll need while under the employment of a licensed contractor.

Learn while you earn

If this seems like a lot of time, here’s the good news: After you finish your 4-month coursework at Entech, you can work and earn a paycheck while you complete your apprenticeship. You’ll be getting paid while you learn!   And because Entech is affiliated with the Connecticut Energy Marketers Association, we have direct relationships with many of the companies that are hiring apprentices. We regularly help our students find apprenticeships!

Our Recommendation: Take all of the courses necessary to obtain an S-2 license. You’ll not only have completed the coursework necessary for any license – you’ll also be ready to start earning.
