Types of air conditioners

Do you want to know what are the types of air conditioners available on the market? We will discuss them below.

Refrigeration systems

Refrigeration systems are a common form of air conditioning unit used in Australia. Functioning as a refrigerator, liquid refrigerant passes through the system to cool the air.

The reverse cycle system, as the name implies, can reverse this process to heat the air and is the most common form of device sold in this country.

All units require a condenser, refrigerant cooler, fan and drainage system, as the by-product of this process is water.


These devices are generally only suitable for small spaces and can often be transported on wheels without installation costs.

No installation is required, but many models require access to a window, floor or sink drain to allow air exchange and allow the unit to collect water to drain.

Window or wall units

These units, also known as window air conditioners, are installed in a wall or occupy part of a window opening, so that the interior of the room has the temperature you want to control, while the fan exhausts. and waste water outside.

These devices are only suitable for small and medium-sized spaces. Expert installation may be required.

Reverse cycle split system

This type of air conditioner generally heats and cools small and large rooms and, as the name implies, is composed of two separate components connected by wires and hoses.

The main unit is hung on the wall near the ceiling of the room where you want to control the temperature. The condensers are usually larger and are installed outside the house. This unit usually contains a motor and fan.

Split systems must have a drain inlet so that the water they draw from the air can escape.

You will usually need a licensed installer to add one to your home because of the complex electrical, plumbing and carpentry requirements.

These units are also available as “multi-head” systems, which allow you to control the temperature of multiple rooms.


These systems can often heat or cool individual rooms or entire homes, depending on the size of the equipment and the number of “zones” allowed.

Heated or cooled air typically flows from ventilation openings installed in different rooms, going there through ducts (large insulated pipes) to the ceiling cavity, the internal air handler and the condenser outside of the unit.

These types of units can only be installed by a qualified professional and may consider an installation cost of $5,000 for an 8.0 kW reverse cycle air conditioner installed.
