Types of air conditioners

Portable air conditioners

Some portable models are little more than personal coolers. Others can cool a small room (up to about 20 square meters). Portable units can be plugged into a normal power point.

Window air conditioners

A window model is usually installed in a window or external wall, and can cool rooms and open-plan areas of up to 50 square meters. While smaller units can be plugged into a normal power point, larger ones may require additional wiring.

Split-system air conditioners

A split-system air conditioner consists of a compressor unit that’s installed outside, and one or more indoor air outlets. They’re usually used to heat & cool one or more rooms, or an open-plan area, of up to 60 square meters.

Inverter Technology

With conventional air conditioners, the compressor is either on (working to 100% capacity) or off. Inverters can vary the compressor speed and maintain the set temperature within a narrow range. Manufacturers claim inverter models are more efficient and reduce running costs.

Cooling only or Reverse Cycle

Reverse-cycle models only cost a bit more than cooling-only models, but you can also use them for heating in winter. While the purchase and installation costs can be high, reverse-cycle air conditioners are among the cheapest forms of heating to run. They cause less carbon dioxide to be produced in power plants burning fossil fuel than other kinds of electric heater
