What is an HVAC System?
An HVAC system is designed to control the environment within a building by regulating temperature, humidity, and air quality. It includes multiple components working together to provide heating, cooling, and ventilation. Here, we will break down the main parts of an HVAC system to give you a clear understanding of how each component functions.
Heating Component
The heating component of an HVAC system is responsible for providing warmth during colder months. It typically consists of:
- Furnace: The main source of heat in most HVAC systems, a furnace heats air that is then distributed throughout the building.
- Heat Exchanger: Located inside the furnace, it transfers heat from combustion gases to the air without allowing the gases to mix with the air being heated.
- Burner: Burns fuel to create heat, which is then transferred to the heat exchanger.

Cooling Component
The cooling component eliminates heat from indoor air to maintain a comfortable temperature. It includes:
- Air Conditioner: Uses refrigerant to absorb heat from indoor air and release it outside.
- Evaporator Coil: Located inside the indoor unit, it absorbs heat from the indoor air using refrigerant.
- Condenser Coil: Located outside the building, it releases the absorbed heat to the outdoor air.
Ventilation Component
Ventilation ensures proper air circulation and maintains air quality. It consists of:
- Ductwork: Channels that distribute warm or cool air to different parts of the building.
- Air Filters: Remove dust, allergens, and other particles from the air to improve air quality.
- Ventilation Fans: Help to circulate air throughout the building and exhaust stale air.
