In most cases, your portable air conditioner will not need to be drained. Edgestar, Avallon and Koldfront portable air conditioners use a condensation exhaust system to expel water vapor collected during the dehumidifying/cooling process. When this situation does occur you will need to drain the internal water tank. Subsequently, one may also ask, why does my portable air conditioner not cool? No Air Comes Out of the Air Conditioner There are many reasons for lack of air flow. The most common cause is a clogged filter. The second reason your portable air conditioner may not be venting air is frost on the cooling coils, also known as the evaporator coils.Do portable air conditioners need to be cleaned?A clean portable air conditioner will result in increased air volume, so the actual housing of the unit should be cleaned every few weeks. Wipe the surface of the unit with a soft, damp cloth when the unit is turned off, and don’t use abrasive chemicals or detergents.
