In 2002, Jason Obrzut graduated from the HVAC Technical Institute in Chicago, kick-starting an accomplished career in the HVAC Industry. Jason began working as a service technician, became an installation supervisor and ultimately a business owner. While working during the day, he returned to the HVAC Technical Institute as a part-time, evening instructor. Teaching quickly became his passion and he scaled back on working in the field to focus on teaching full time. While teaching, Jason developed, wrote and implemented the curriculum that is currently being taught at the school. His dedication to his students and the institution was evident and he soon became the school’s Director of Education and lead HVAC/R instructor. In 2016, The ACHR News recognized Jason as one of the “Top 40 Under 40” in the HVAC industry. He is affiliated with numerous HVAC industry organizations, including Refrigeration Service Engineers Society (RSES), The Air Conditioning, Heating, and Refrigeration Institute (AHRI), the ESCO Group and HVAC Excellence. Jason served on AHRI’s Safe Refrigerant Transition Taskforce (SRTTF) as chairman of the technician outreach committee. At HVAC Excellence’s 2016 National HVAC Educators and Trainers Conference (NHETC), Jason participated in the first annual Teachers-N-Trainers (TnT) competition and took first place in a field of over 60 participants. Jason is one of only 125 instructors nationwide who have held the title of Certified Master HVAC/R Educator (CMHE), and he holds Certified Subject Matter Educator (CSME) certificates from the ESCO Group.
