HVAC Systems and Technicians
An HVAC system circulates air in a home and controls temperature. It can also remove humidity. Some systems use a central blower that sends air to a number of rooms, while others use individual units that circulate air throughout the home. Regardless of how your HVAC system works, it is crucial to understand what your specific needs are and choose the right system for your home.
HVAC systems are essential in residential structures, commercial buildings, hospitals, vehicles, and even marine environments. Their job is to regulate temperature and humidity by using fresh air from the outside. As part of a larger network, they can save energy and use renewable sources. Heating and cooling systems can even be integrated into a building’s automation system.
HVAC systems are complex machines that move air and control indoor temperatures. They typically contain three major components: an outdoor unit, ductwork, and filters. These components are interrelated to create a comfortable environment and ensure healthy living conditions for occupants. Because the HVAC system is so large and complex, a breakdown can happen quickly.
HVAC technicians are skilled in refrigeration, heating, and air conditioning. In the US, technicians can earn an associate’s degree or pursue an apprenticeship program. This training typically involves classroom lectures and hands-on tasks. Once trained, HVAC technicians can take various certifications. They can work on heat pumps, air conditioning, commercial refrigeration, and gas heating.
