My Air Con is not cooling/heating/working efficiently?

Air conditioners need to be regularly cleaned and serviced in order for them to work efficiently. Every six months, you should take the filter out to clean it thoroughly and an air conditioner should be serviced by a licenced installer every 12 months. Please note that air conditioner’s are best run at the following temperature ranges in order to be energy efficient: 

Cooling - 25 degrees 

Heating – 18 degrees
