Understanding Air Conditioning

Air Conditioning works to cool or warm your home, creating a comfortable living environment by filtering the air and removing the moisture which causes humidity.





The principle behind air conditioning is simple. Two coils (one inside your home, the other outside) are connected by pipes filled with refrigerant. This fluid has the property of easily absorbing and rejecting heat, and is pumped through this circuit of pipes by a compressor. Two fans pass air over these coils.

During the cooling cycle, warmed refrigerant circulates through the outside coil where it releases heat and cools down. It moves back inside, and is circulated through the indoor coil.

The hot air inside your home is blown over this cold coil (and filtered and dehumidified at the same time) where it cools down and, in turn, cools your home. During this process the refrigerant warms up and moves back outside to repeat the cycle. (Your domestic fridge is a good example of this process.)



When heating your home, warmth is generated by ‘reversing’ the operation of the air conditioner. Instead of expelling the hot air and circulating cool air it does the reverse — hence the term ‘reverse cycle’ air conditioning.

User Tips


Where to locate your Air Conditioning unit:

To ensure optimum performance,  the outdoor section of split systems should have adequate ventilation and, if possible, be placed in a shady ventilated area.

Direct sunshine and restriction of air access will reduce the air conditioner's performance.

Adequate clearance from obstructions is essential to ensure that exhaust air is not re-circulated back through the outdoor coil.

The outdoor unit must have at least 800mm in front of it free area to ventilate efficiently, the larger the area the better. We would also suggest 75 to 100mm between the back of the unit and the wall.




Saving Energy

Generally the best temperature to set your air conditioning to is around 23 - 25°C in summer and 19 - 21°C in winter.

You can save considerably on the amount of energy consumed for each 1°C of cooling or heating that you do without. For example when it’s 35° outside, setting your air conditioner to around 25, rather than say, 20, can save a significant amount of energy without your system continually turning off & on. Run the Inverter system constantly, vary the fan speeds & temperature,dont turn the system on & off. Balance between comfort and efficiency of the system.

Switch to de humidify mode early in the evening to prevent that cool air breeze but to stop the humidity from building up again.

Shade your windows in summer with curtains, awnings, or shutters to reduce heat absorption by up to 80%. Heavy linen curtains with pelmets will also help trap heat in winter. This all helps in reducing the overall running costs of your air conditioning.

Caring for your Air Conditioning unit

Air conditioning maintenance is always based on individual use, but in general you should check filters once a fortnight and replace the batteries in your remote control (where applicable) once a year. We would recommend changing batteries at the commencement of daylight savings at the same time as your smoke detector. At the same time check the outdoor unit is clear of leaves, shrubs or dirt build up. To clean, simply brush or hose the outdoor coil. Please read the filter section below for more information. Get your system serviced by a Daikin trained tecnician annually, usually before it gets hot. Each of our technicians carry a Daikin analyer which tells us the performance history of your system, we can also monitor pressures and temperatures to ensure the system is working within its performance limits. Aslo we test & flush the drain. The fan coil is treated to stop dirt and grime build up, ensuring maximum air flow over the fan coil and maintaining maximum efficiency of your air conditioner.This service also includes us cleaning and checking the indoor filters and treating the fan coil with a product called Mizo Foam which, cleans, kills germs and bacteria, deodorises, helps save energy and is environmental friendly. Should you wish to learn more about Mizo Foam please watch the attached link. Cleaning your Air Conditioner using Mizu Foam .
We also treat the outdoor unit with a product called Laontech which helps to slow down the corrosive issues we find here on the coast.



The primary purpose of filters is to protect the indoor coil from dust build up which could reduce the overall performance of the air conditioner. It is important to regularly check and clean your filter. The majority of service calls are due to a dirty or blocked filter and in most cases a service fee is charged even if the air conditioner is under warranty.

Most air conditioners in the split range now have a specially treated additional filter that traps fine pollens etc which greatly helps people suffering from allergies. Daikin air conditioners have the seal of approval from the National Asthma Council of Australia.

Remember whenever your Airconditioner is on, be it heating, cooling, fan only, or on the dehumidify setting, it is always cleaning,deodarising & even disenfecting the air that you breathe.

Ducted systems can now have electrostatic air filters fitted, which is the ultimate in home or office filtration.

Air conditioning maintenance is just one simple fortnightly operation. Because the air filter in any air conditioner screens out dust and pollen particles, it should be removed regularly and washed. This simple operation is covered in the individual unit’s instruction manual.


Bad odours in your air conditioners are caused by bacteria colonies forming a biofilm over your coils and fan blades. The only way to stop the smell is to have a very thorough cleaning of your ac system.
