Have the air conditioner pads and tray cleaned to improve the efficiency of your air conditioner and run it on cool rather than vent to prevent dust particles entering your home.

If you have an air conditioner that draws outside air into the house then it is probably full of ash and debris from the fires. As well as reducing the efficiency of your cooling system this debris can enter your home, contaminating the air.

You should arrange to have the air conditioner cleaned and serviced as soon as possible and try not to use it until this servicing is done.
