A 2-3 star reverse cycle air conditioner can cost between 30 and 34 cents an hour to run, while a 4-5 star reverse cycle air conditioner can cost between 34 and 38 cents an hour.

A ducted reverse cycle air conditioner with a zoning system costs 36 and 54 cents per hour, while a whole-house reverse cycle air conditioning will cost between 63 and 91 cents per hour.

In contrast, a fan or an evaporative cooler will cost around two cents per hour to run; so if you have both air-conditioners and fans, only run the air-conditioning when necessary.

Factors that impact on these running costs include insulation; A house that is well insulated will obviously cost less to cool than a house that has no insulation. The installation of your air conditioner by your Gold Coast air-conditioner specialist is also a factor, depending on how well it is sealed.

The other major factor is the temperature at which your air conditioners set. For each degree you raise the temperature you can save up to 5% on air conditioning costs.

Keeping your filters clean will obviously help, as the air conditioner has to work much harder if it is operating through a layer of dust.

Another money saver is closing curtains and blinds, particularly those facing the sun. If you have a window mounted air conditioner, then you obviously need to keep the door to that room closed.

Choosing a competent Gold Coast air-conditioner specialist will obviously help, as they can advise you on many of these factors and discuss with you the most appropriate location and type of air conditioning.
