Q: How does an evaporative cooler work?

A: The evaporative coolers provide a cooling effect by natural evaporation.  They require a full tank of water/ice and need a well-vented area.  Please note these units are not suitable for server rooms as they add humidity to the area.

Q: How do you work a portable air conditioner?

A: The units pump out cool air that has been chilled through heat extraction. The hoses must be positioned in a suitable area where the warm air can be ducted away from the area being cooled – either a window or a ceiling void.  The hoses should be as straight and as horizontal as possible so the unit can work efficiently.

Q: My air conditioning unit isn’t working or is not cooling properly, what can I do?

A: The most common cause is the unit being set at too low a temperature. See our blog for further information
