What Does an HVAC System Do and How Does It Work?

HVAC stands for heating, ventilation, and air conditioning. It is a system that regulates and circulates hot and cooled air in residential and commercial buildings, from homes to offices and indoor stadiums. A qualified HVAC technician is responsible for installing, maintaining, and repairing the heating, ventilation, air conditioning, and cooling systems that control temperature and air quality in buildings. HVAC systems are designed to provide both cooling and heating capabilities.

They are typically installed in homes, offices, and other commercial buildings to regulate the temperature and air quality. The system is composed of several components such as thermostats, air treatment systems, compressors, and refrigerant levels. All of these components must be installed and maintained by a trained HVAC technician. HVAC technicians are responsible for assembling and installing the ducts that distribute heated or cooled air from the HVAC system.

This process can be complex due to the risks associated with the system such as fire and carbon monoxide. In some cases, other merchants may work with HVAC technicians to help install or repair cooling and heating systems. HVAC technicians may also offer service contracts to their customers for regular maintenance of heating and cooling systems. In order to become a professional HVAC service technician, it is important to have a comprehensive understanding of the system.

This includes practical training in basic electricity, motors, HVAC control, basic refrigeration, air conditioning systems, heating and boiler systems, duct design, floor plan reading, load calculations, commercial cooling systems, special equipment, building regulations, automation, and troubleshooting. New HVAC technicians often start their careers by performing more basic tasks such as cleaning HVAC systems and operating ducts before moving on to more difficult tasks such as installations, troubleshooting and repairs. Repairs to household refrigerators or window air conditioners are usually performed by appliance repair services rather than by HVAC technicians.
