Heating and cooling systems

Fed up with the heat? If you wish to install an air conditioner, or repair an existing heating and cooling system, we suggest hiring a technician to help you. There are many systems to choose from, please compare costs and services by requesting quotes from several professionals.

Stay comfortable in your home

Air conditioning regulates the temperature and humidity of indoor areas. This allows you to stay comfortable throughout the year. In many areas of Australia, the summer months can get very hot; heat exhaustion can be very damaging to your health. Staying cool and finding shelter from the heat is essential for you to enjoy your day. This is why many Australians opt for air conditioning to keep their homes cool and comfortable.

Reverse-cycle air conditioners provide both heating and cooling to regulate the indoor temperature. There are also Cooling only and Heating only systems (although in Australia Heating only systems are unusual).

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 and cool one or more rooms, or an open-plan area.

Many different types of systems available

Points to consider

How it works:

The best way to choose a cooling system, and keep your system functioning correctly, is to understand the basic elements of how an air-conditioner works.

An air-conditioner uses the heat exchange properties of condensation and evaporation.

The Refrigeration Cycle:

  1. Condensing coil
  2. Expansion valve
  3. Evaporator coil
  4. Compressor

Evaporation is the process where a liquid turns to gas through heat absorption. Condensation is when a gas turns back to a liquid form, when heat is released.

Air conditioners are designed to use a compressor to create pressure changes between two compartments of the air-conditioner. This would cause the evaporation and condensation that is needed to pump a refrigerant around.

A refrigerant liquid is pumped into the cool compartment (the evaporator coil). The low pressure in this compartment causes the refrigerant to evaporate into a vapour, which takes the heat with it. In the second compartment (the condenser), the refrigerant vapour is compressed and pumped through another heat exchange coil, which condenses it back to a liquid form and releases the heat previously absorbed from the initial compartment. When this process is repeated, it can actively change the temperature of a room. By extracting the heat from one side of the unit to the other side, the initial side is cooled as the energy is extracted from that side.

Many air-conditioners use halogenated chlorofluorocarbons (CFC) as a refrigerant. This substance is also known as Freon. CFCs are used as the heat exchange properties are very good. Laws help to protect the environment and minimize further damage, so there are strict regulations for the emissions of CFCs by cooling units.
