What is an air conditioning system?

An air conditioning system controls indoor temperature to create a more comfortable environment. Depending on the system, it can provide cooling, heating or both throughout a home or business.

Air conditioning system definition

An air conditioning system is equipment used to control the temperature of an indoor space. Depending on the type, it can cool, heat or provide both functions to help maintain comfortable conditions.

Common air conditioning systems

Air conditioning comes in several forms, with different systems suited to individual rooms, multiple areas or whole buildings.

  • Split systems: Heat or cool individual rooms and smaller spaces.
  • Ducted systems: Condition multiple rooms through connected ducts.
  • Reverse cycle: Provides both heating and cooling from one system.
  • Evaporative cooling: Uses water evaporation to cool fresh air.

How air conditioning systems work

Air conditioning systems move heat to control indoor temperature. Depending on the system, they can cool a single room, several zones or an entire building.

Where these systems are used

Air conditioning systems are used in homes and commercial properties. The right type depends on the building, the areas being conditioned, and the comfort requirements.

How the system operates

Most refrigerated systems use refrigerant to absorb heat from one area and release it elsewhere. Reverse cycle systems can reverse this process to provide heating.

Where air conditioning is used

Different air conditioning systems suit different spaces and comfort needs. Here are some common situations where each type may be used.

Cooling a single room at home

A split system can suit a bedroom, living room or other individual area where targeted temperature control is needed without conditioning the whole home.

Conditioning the whole home

Ducted air conditioning can distribute conditioned air across multiple rooms, making it a practical option when comfort is needed throughout the home.

Heating and cooling year-round

Reverse cycle air conditioning can provide cooling in summer and heating in winter, giving households both functions through the same system.

Cooling with fresh outdoor air

Evaporative cooling draws warm outdoor air through water-soaked pads, then circulates the cooled, fresh air throughout the home.
