HVAC systems, which are responsible for heating, ventilation and air conditioning, can be found in most modern buildings. As central air systems, these units are composed of several parts that are all required for proper functioning. The HVAC unit is the most important part of a building’s heating and cooling system.


Most homeowners are more familiar with thermostats than any other part of HVAC networks. Without thermostats, homeowners would be forced to either turn their units off manually or use timers to set how long they blow air for. This would result in higher energy costs and less utility for homeowners. Thermostats have small metal strips that are sensitive to temperature changes, turning central air systems once they reach homeowners’ desired temperatures.


Also known as ductwork, ducts are usually made of rigid steel pipes or flexible combinations of plastic, fiberglass, and wire. The former style of ductwork is usually reserved for commercial buildings. These rigid pipes, typically made of galvanized steel or aluminum, are often coated with insulation to help cut down on energy usage. Flexible ductwork is used in residential applications because ducts have to be carefully threaded through walls, ceilings, and floors.


Homes and buildings are outfitted with multiple intake vents, each of which contains filters. If not for filters, the dust, dirt, and debris would find its way into the inner workings of HVAC units, causing them to have shorter lives and not work as well. Filters are one of the few components of HVAC systems that need to be regularly replaced.


Vents, typically located in floors and ceilings, connect surfaces inside homes and buildings with ducts. They also keep objects from falling into vents, potentially affecting their performance.
