Although an evaporated cooler is a simple system, it still needs regular servicing. For new units, we recommend a service every 2-3 years and, for older units, we recommend an annual service.
You’ll be surprised at the difference a service can make to the flow of air, which slows down over time as dirt builds up on the air filter. Not only that, as you can imagine in a system that deals with moisture, mould and mildew can begin to grow and affect the quality of the air that is distributed through the vents and into your rooms, and lungs!
