Nicholas Griewahn teaches heating, ventilation, air conditioning, refrigeration, and electricity classes at NMU. He has worked as an HVACR service and installation technician for several years, which entailed installation, maintenance, troubleshooting and repair of mechanical HVACR equipment on the residential and commercial level. He is EPA universally certified and NATE certified in Heat Pumps and Air Conditioning. Instructor Griewahn has served as activities and volunteer chair with a local fisheries management organization and as the vice president of the Wildlife Society student chapter. In addition, he has been a volunteer tutor to students in the HVACR programs, as well a proctor for EPA certification and industry competency exams.
Instructor Griewahn encourages interested students to obtain degrees in the fast-paced and exciting career of HVACR. This industry is a necessity for homes and business, which ensures job security for its workers, and given the projected shortage of technicians over the next 10-20 years, students can feel comfortable in knowing that there will be positions available to them upon graduation. This is a career that fosters teamwork and allows for interaction with other members of the team, as well as members of the community.
Instructor Griewahn advocates The School of Technology and Applied Sciences' HVACR program due to smaller class sizes and the individual attention given to students at a reasonable cost.
