HVAC Technician

Heating, air conditioning, refrigeration mechanics and installers, often referred to as HVAC technicians, work on heating, ventilation, cooling and refrigeration systems that control the air quality in many types of buildings. They mostly work in residential homes, schools, hospitals, office buildings or factories. Their work sites may be very hot or cold because the heating and cooling system they must repair is broken. Working in cramped spaces is common.

What does a HVAC Technician do?

HVAC technicians typically do the following:

  • Travel to work sites

  • Follow blueprints or other design specifications to install or repair HVAC systems

  • Connect systems to fuel and water supply lines, air ducts and other components

  • Install electrical wiring and controls and test for proper operation

  • Inspect and maintain customers’ HVAC systems

  • Test individual components to determine necessary repairs

  • Repair or replace worn or defective parts

Heating and air conditioning systems control the temperature, humidity, and overall air quality in homes, businesses and other buildings. By providing a climate controlled environment, refrigeration systems make it possible to store and transport food, medicine and other perishable items. Although trained to do all three, HVAC technicians sometimes work strictly with heating, air conditioning or refrigeration systems. They also may specialize in certain types of HVAC equipment, such as water-based heating systems, solar panels or commercial refrigeration.

Depending on the task, HVAC technicians use many different tools. For example, they often use screwdrivers, wrenches, pipe cutters and other basic hand tools when installing systems. To test or install complex system components, technicians may use more sophisticated tools, such as carbon monoxide testers, voltmeters, combustion analyzers and acetylene torches. When working on air conditioning and refrigeration systems, technicians must follow government regulations regarding the conservation, recovery and recycling of refrigerants. This often entails proper handling and disposal of fluids.

Some HVAC technicians sell service contracts to their clients, providing regular maintenance of heating and cooling systems. Other craft workers sometimes help install or repair cooling and heating systems. For example, on a large air conditioning installation job, especially one in which workers are covered by union contracts, duct-work might be done by sheet metal workers and duct installers or electrical work by electricians. In addition, home appliance repairers usually service window air conditioners and household refrigerators.

 What is the workplace of a HVAC Technician like?

HVAC technicians mostly work in residential homes, schools, stores, hospitals, office buildings or factories. Some technicians are assigned to specific job sites at the beginning of each day. Others travel to several different locations making service calls.

Technicians generally work indoors but some may have to work on outdoor heat pumps even in bad weather. They often work in awkward or cramped spaces and some work in buildings that are uncomfortable because the air conditioning or heating system is broken.
