What Is HVAC Trade?
HVAC stands for Heating, Ventilation, and Air Conditioning. The HVAC trade focuses on the systems that heat, cool, ventilate, and control the air inside homes, businesses, schools, hospitals, and other buildings.
HVAC technicians install, maintain, inspect, troubleshoot, and repair heating and cooling equipment. Depending on their training and specialization, they may work with furnaces, air conditioners, heat pumps, ventilation systems, refrigeration equipment, thermostats, electrical components, and other climate-control systems.
HVAC is a technical, hands-on trade that combines mechanical skills, electrical knowledge, problem-solving, customer service, and safety.
The U.S. Bureau of Labor Statistics currently projects 11% employment growth for heating, air conditioning, and refrigeration mechanics and installers from 2025 to 2035, which is much faster than the average for all occupations.
