Educational programs are available at the undergraduate level, typically as certificate, diploma or associate degree programs. Coursework can include electrical systems, building codes, duct work, installation, circuit systems, welding and HVACR system design. Professionals in this field may also complete apprenticeship programs, which may last up to five years.

In some states, HVACR workers are required to obtain licensure, which commonly requires the completion of an exam and a minimum amount of professional experience. Professionals who work with refrigerants are required to become certified through an organization approved by the Environmental Protection Agency. Refrigerant certification is available in high-pressure, low-pressure or small appliance.

Job Description for a Cooling System Technician

Climate control systems have a lot of mechanical, electrical, and electronic components. Cooling system technicians must correctly install the particular cooling system and all of its components. Sometimes, especially during repair, this involves installing items like motors, electronic component boards, compressors, evaporators and relays. After installing the system, cooling technicians typically install the fuel and water supply lines, drain lines, ducts and vents, among other components. Cooling technicians use experience, blue prints, sheet metal shears, wrenches, gauges, torches, drills, multi-meters, and other equipment.

High job growth is projected for all heating, air conditioning and refrigeration mechanics and installers though 2028. Applicants with postsecondary education, completion of an apprenticeship, experience from vocational courses or an internship should be prepared to compete for jobs in this field.
