Heating Ventilation Air Conditioning and
Refrigeration Maintenance Technology

High demand for jobs in versatile field


Feb. 13, 2014 — Interested in project management, computer programming or diagnosing the problem with a heating or cooling system? TCC’s Heating Ventilation Air Conditioning and Refrigeration Maintenance Technology (HVAC/R) program trains students for a gamut of job opportunities in a field growing at an impressive rate.

“HVAC/R has the highest demand for new workers among the technical fields – that’s both in Virginia and across the nation,” said Harlan Krepcik, program head for the HVAC/R program at the college. “The income opportunities are there. The job opportunities are there. The future is bright for someone who wants to get into this field. The demand is enormous, and every year, it gets bigger.”

TCC offers a 41-credit certificate over three semesters and is looking to expand that to an associate of applied science degree by fall. Classes range from Air Conditioning and Refrigeration Controls to Heating Systems to Psychometrics to Advanced Troubleshooting and Service during a student’s final semester.

Harlan Krepcik, center, has taught HVAC/R at TCC for 29 years.

While knowledge of basic algebra is helpful, the program is designed to prepare those with no prior background in the field.

“The majority of our students know nothing about heating and air conditioning when they enroll; many new students have never held a volt meter nor do they know what one is,” Krepcik said. “Students who attend all the classes and master the material do quite well.”

The program also enrolls veterans with some technical background and current employees within the industry looking to increase their earning potential. Women do quite well, also, Krepcik said, though heavy lifting can be required.

The largest misconception about the field is that it’s dirty, blue collar work only. Maintenance and diagnosis are parts of the field – just not the only parts.

“We have project managers, people who spend all day writing programs for large commercial systems, people working in air purification,” Krepcik said. “This is an energy management business; thermal imaging and air quality management are specialty areas of HVAC/R. We’re into all kinds of things people don’t associate with HVAC/R.”

Krepcik’s first job was for a plumbing and heating operation in Nebraska, manual labor that he didn’t initially find appealing. But he enjoyed math and science, problem solving and liked the ability to put theory into practice in HVAC/R. He holds two degrees from TCC – one in applied science and another in business – in addition to bachelor’s and master’s degrees from New York Institute of Technology, the latter paid for by his employer. He has taught at the college since 1989 and worked locally for Carrier and Trane.

The TCC program teaches the basic science of HVAC/R – equipment varies from company to company, so some learning is done on the job. While students begin with the basic science of heat transfer, they evolve to work with live electrical circuits, wiring, systemic chemicals and materials so cold the mere touch means frostbite. Safety is stressed inside the classroom, which is shaped to include as much hands-on time as lecture.

While the technical skills are valuable to landing a job, Krepcik stresses the importance of attitude and self investment. Employers seek employees who are strong in customer service, as losing one client in a competitive field is not something they tolerate. The best candidates are also ones who have taken their education seriously.

“The better companies look for someone who self invests,” Krepcik said. “When I worked at Trane, we prescreened applicants by their resumes. We wanted employees we didn’t have to micromanage. If someone is self investing by getting a certificate or better yet a degree – that’s what we were looking for. It shows that you can finish what you started.”
