To get the best performance out of your evaporative air conditioner, it is a good idea to ensure that you have a selection of windows or outside doors open to provide a form of ventilation. The reason why this is a necessary requirement is to let the hot air to escape from your home. For the best results, open the windows or outside doors which sit the furthest distance from your evaporative air conditioning vents or ducts. When it comes to the rooms that feature air conditioning vents, you’ll want to have an exhaust spot (an open window or door) that is roughly twice the size of the vent, if possible.
If it is a particularly humid day with moist air, the evaporation levels will not be as high as usual, reducing the cooling effect. In these situations, it is best to use the ventilation mode on your unit to enhance the exhaust area while using the high-speed option for the fan.
