What does an HVAC technician do?
An HVAC technician installs, maintains and repairs heating, cooling and ventilation systems.
Duties and work settings
Filters, airflow, electrical connections, controls and refrigerant circuits need distinct checks. Measurements are more reliable than replacing parts at random. Indoor air quality and energy use matter alongside comfort.
Skills, safety and entry routes
Electrical, pressure and refrigerant hazards require safeguards. Working with certain refrigerants may require certification; follow manufacturers and current local rules.
