  • To open the air conditioner, firstly remove the outer case, which is the covering of the air conditioner with care. There would be easy push buttons on either side of the chance to help you do so. Once open, it reveals the interiors of the air conditioner, such as fans, coil, and compressor.
  • Next, place the exterior covering of the air conditioner in a secure location till you are cleaning the air conditioner. Ensure that it is accidentally not broken by you. We advise you to wash that as well.

It is advised to wear a mask or cover your face if you haven’t cleaned your air conditioner in a while. Get to a safe distance and blow air at pressure.

  • Use a cleaning brush to eliminate the other dust particles stuck in your air conditioner. You can also use a toothbrush or a micro-fiber cloth at home that you can easily find.

  • Wash the drip tray as well with the jet spray. You may also run a light hand over it with a wet cloth to avoid additional pressure. 
  • Now, it’s time to reassemble the air conditioner. But, hold on. Don’t rush so soon. Do you wish to get a short circuit in your house by making wet appliances work? First, let it be for a couple of hours till it is completely dry, and then assemble it.
