HVAC Faculty and Subject Matter Experts (SME)


Scott Oakley, CMHE, NATE

Certified Master HVAC/R Educator (CMHE

2019-2020 NATE Technical Committee Member

My start in the HVACR industry was the same as yours is now. I attended Universal Technical Institute (UTI) in Phoenix, Arizona, and graduated in 1976. Technical education is crucial to your success. Through the last 44 years, I have been involved in every single facet of the industry from Technician, Contractor, Facilities, Sales, Business Owner, and Instructor. My Certified Subject HVAC Educator credential in the result of a 750 question series of proctored exams aimed to determine at-hand competencies.

After I graduated from UTI, I immediately went to work in the commercial refrigeration service field. Within a few years, I moved on to become the Service Manager of a large commercial air conditioning firm in the Arizona area. Ambition soon called, after eight years, to contracting business owners during which I relocated to California. This new firm specialized in new construction installation and maintenance service operating throughout the State of California. I have been involved in companies as a single service technician, to others with 150 employees.

Over the past recent years, I have been working as both a face-to-face and online, blended HVACR Instructor. I am the author of Commercial Ice Machines…only (available on Amazon), focusing on the ice industry, the ice machine, and icemaker through health department compliance.  I am a contributing author of the new book entitled Electricity for the HVACR Technician. Published by CDX Learning Systems, written by a group of experienced HVACR service professionals, Electricity for the HVACR Technician emphasizes the practical, essential information that technicians will use on a day-to-day basis and allows new technicians to apply their knowledge and skills from the classroom in successfully troubleshooting and repairing electrical problems in the field. During the past three years, I have served as the ItsAboutQ liaison and have helped pioneer the Corporate Training Program (CTP), aka The Employer Participation program. The CTP brings a higher level of workforce management through accurate reporting and coaching.

I am a firm believer in the evidence of credentialing and certification because they both show the world that you can do the task and that you understand the science and purpose of the job. For Instructors, the credential is the Certified Master Heating, Ventilation, Air Conditioning, and Refrigeration Educator (CMHE). The CMHE encompasses Technical Training, Heat Pump, Electrical, Air Conditioning, Light Commercial Air Conditioning, Electric Heat, and Commercial Refrigeration. In addition to the CMHE, I am NATE (North American Technician Excellence) certified in Heat Pump and Air Conditioning Service and Installation. Starting in 2019, I serve on the NATE Technical Committee, helping to update the NATE exam banks continuously.  I have been previously state-licensed as an Air Conditioning Contractor, Commercial Refrigeration Contractor, and General Building Contractor since 1977; now retired to serve the educational community.

In 2020, the world has changed. Technicians are required to understand system automation and possess in-depth technical knowledge. I am here to help you achieve the goal of confidently working in this industry.
