Dunwoody HVAC & Refrigeration Technology

The HVAC & Refrigeration Technology program teaches you to design, estimate, install, and maintain modern Heating, Ventilation, Air Conditioning and Refrigeration (HVACR) systems. Dunwoody’s program provides graduates the flexibility to go down various career paths in the industry and take on a wide variety of roles throughout their career.

With a thorough understanding of all aspects of HVACR systems upon graduation, you’ll be ready to join a pipefitters union or work for a residential and/or commercial HVACR service company, a construction or engineering services firm, or take on roles with organizations who need in-house HVACR and building controls and management expertise.

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. Learn project management and estimating principles and software as well as how to fabricate and install duct fittings.

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.

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.

The program will prepare you to earn several HVAC Excellence certifications.

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.
