Every use

  • Run the ‘dry out’ program if your air conditioner has it. This evaporates the moisture that’s condensed on the heat exchanger, preventing mould and foul odours.


  • Clean and/or replace filter screens in the indoor unit of a split-system, or as per the instructions for your ducted system. (Do this more often if your air conditioner is always on, you live in a very dusty environment or you experience a noticeable drop in performance.)
  • Wipe down the indoor unit or any ducts or vents with a soft damp cloth.


  • Clean the outdoor unit and remove vegetation/obstructions/spiders as necessary.
  • Inspect HEPA or carbon filters and replace as necessary.
