HVAC technicians install, maintain, troubleshoot, and repair heating, ventilation, air conditioning, and refrigeration (HVACR) systems in residential, commercial, and industrial buildings. They work with mechanical, electrical, and computerized controls to keep buildings comfortable, energy-efficient, and properly ventilated.
HVAC technicians typically complete a technical or trade program and/or an apprenticeship combining classroom instruction with hands-on training. Programs commonly cover heating and cooling systems, refrigeration, electrical systems, controls, troubleshooting, safety, and refrigerant handling. Certification or licensing requirements vary by location and area of specialization.
The outlook for HVAC technicians and HVACR professionals is strong, supported by new construction, replacement and repair of aging equipment, increasingly sophisticated climate-control systems, and growing demand for energy-efficient heating and cooling technologies. The field is also becoming more technology-driven as modern HVAC systems incorporate computerized controls and connected equipment.
HVAC technicians work in homes, businesses, schools, hospitals, industrial facilities, and other buildings. They may work indoors or outdoors and often work in cramped spaces, on rooftops, or in uncomfortable temperatures when heating or cooling systems are not operating properly. Full-time work is common, and some technicians work evenings, weekends, overtime, or emergency service calls.
