• Evaporative coolers: the newer ones self drain but they still need
flushing periodically and the pads also require changing when they begin
to rot. They also need the water distribution cleaned or you can lose
cooling due to the pads drying out. (Chemical dosing is a far better
option that washing out your unit, high pressure water will damage your
cooler pads)
• Air Conditioners: the return air filters require cleaning. The frequency depends on how dusty the house is. If not cleaned the unit can ice up and stop working. They also need the condenser (outside radiator bit) dust free with an unobstructed air flow. This can be cleaned by brushing in the direction of the fins or blowing it out using compressed air/gas. Ensure the drain outlet is unrestricted. Wipe the surface of the inside unit down at regular intervals as they do gather dust
