Dunwoody HVACR Systems Servicing

Dunwoody’s HVACR Systems Servicing program teaches you to maintain modern Heating, Ventilation, Air Conditioning and Refrigeration (HVACR) systems as well as troubleshoot, diagnose, and correctly repair environmental and stand-alone cooling systems.

Through hands-on learning—taught by instructors with extensive industry experience—you will be prepared to maintain today’s complex HVACR systems, which consist of multiple mechanical, electrical, energy management, and electronic components. Conduct lab experimentations with industry-standard equipment and utilize computer and lab simulations to understand topics like heating systems, cooling systems, commercial and industrial refrigeration service, HVAC control concepts and building systems operations.

You’ll also receive one-on-one face time with local employers, who provide insights on career opportunities, what to expect in industry, and what types of employees they are looking for.

An OSHA 10 Construction Card is offered to students who successfully complete the required 10 hours of training.

Upon graduation, you’ll have in-depth knowledge of furnaces, boilers, chillers, and refrigerators. You will also be prepared to take the Minnesota’s Special Engineers Boiler Operator License, which allows you to legally operate boilers; EPA Section 608 Certification by Esco Institute, which allows you to legally handle refrigerants, universally; and Hydrocarbon Refrigerants Certification, ensuring you have a solid understanding of the refrigeration cycle and proper handling of CFC, HCFC, and HFC refrigerants.

HVAC Excellence, the largest provider of certification in the HVACR industry, has accredited all of Dunwoody’s HVAC programs. This certification ensures that Dunwoody’s programs meet or exceed industry standards for quality technical education.

This degree directly transfers into Dunwoody’s Bachelor of Science in Construction Management or Bachelor of Science in Business Management & Leadership.
