What Are Some HVAC Components in Addition to Air Conditioners?

Components of heating, ventilation and air condition (HVAC) systems in addition to air conditioners include furnaces, heat exchangers, ducts, vents and thermostats. Evaporator coils and refrigerant lines are other important parts.

HVAC systems incorporate heating, ventilation and air conditioning into single home systems. Because they do so many jobs at once, they contain many different parts.

The furnace or boiler is one of the main components of an HVAC system. The furnace uses electricity or fuel to produce heat. It is usually one of the largest parts in the system.

The heat exchanger is responsible for transferring heat to the rest of the system. It usually consists of a metal tube or plate.

Ducts are important parts of both the heating and cooling aspects of an HVAC system. These metal or fiberglass tubes carry cool or warm air from the air conditioner or furnace to the rest of the home. These are insulated and sealed to prevent cool or warm air from escaping from the system and usually run through the entire home.

Vents are also important parts of both aspects of the system. Vents are openings in the ducts that allow cool or warm air to enter rooms in the home.

Thermostats allow users to control the system. Some thermostats direct the system to turn on at a specific temperature, whereas others can allow temperatures in the home to fluctuate throughout the day.

Although evaporator coils are related to the air conditioning component of the HVAC system, they are located outside of the air conditioner. Usually, the evaporator coil is located in or around the furnace. It is responsible for transferring refrigerant from the air conditioner to the rest of the system. As it runs, it absorbs warm air and condenses the humidity in the air, allowing cool, dry air to run through the system.
