HVAC TECHNICIAN COURSE

HVAC is an abbreviation for heating, ventilation, and air conditioning. A qualified HVAC technician is a technician who installs, maintains, and repairs heating, ventilation, air conditioning, and refrigeration systems that control the temperature and air quality in buildings. HVAC/R is an alternative abbreviation.

HVAC technicians install and maintain heating, ventilation and air conditioning systems. They are hired by maintenance companies where their services are hired out. Many HVAC technicians also work in large companies that have high maintenance needs.

Order any supplies or equipment needed for HVAC maintenance or installation as needed
Ensure availability of all items needed for an HVAC project
Ensure calibration of thermostats and other controls
Perform checks on motors and belts and handle lubrication duties
Change filters and replace any parts as they wear out
Repair motors and service steam and hot water boilers
Ensure that chemical compositions in equipment are adequate at all times
Handle conduit running for HVAC equipment

When a building is being constructed, construction foremen confer with HVAC technicians in order to design buildings so that HVAC systems can be accommodated properly.

Both homes and businesses hire the services of HVAC technicians. While they perform different duties in different types of environments, the essence of their work remains the same. If you are interested in finding out more about an HVAC technician’s work day, you may find the following list of duties interesting
