Why ITEC Training Stands Out for Gas Heating Education

At ITEC, we believe that HVAC training should be more than just memorizing terms, it should prepare you for success in the field. That’s why our courses are built around three core principles:

  • Real-world application: Every topic is reinforced with hands-on labs where you’ll work directly with gas heating equipment.
  • Industry-relevant skills: Our curriculum is designed with input from experienced HVAC professionals and employers, ensuring you learn the techniques most in demand.
  • Recognized certifications: Completing this course earns you the ITEC Gas Heat 1 certification as well as the ESCO Ready to Work Gas Heat credential (with a $15 exam fee).

With ITEC’s approach, you’ll not only gain knowledge—you’ll also gain confidence to step into real HVAC roles, whether you’re starting your career or looking to specialize further.
