Issue My air conditioner is not cooling at all. Possible Cause Unit is not operating in cooling mode. Solution Set the unit to be in cooling mode, and lower the set temperature. TIP: Run the unit before it is needed. For example, run the unit in the morning before the area gets hot, and continue to run the unit all day long in order to maintain a low temperature. My air conditioner blows cold air, but does not lower the room temperature. My air conditioner is not heating properly. The compressor is not on. The ambient temperature is too high. The filter may be dusty or blocked. Blocked exhaust port. The unit is not vented. The area of the room is too large. Open windows and doors. Too many heat sources. The room/garage may be inadequately insulated. The ambient temperature is too high. Direct sunlight is heating the room. The filter may be dusty or blocked. Obstructed air intake or exhaust ports. The heat pump will not work properly if ambient temperature is below 50F. The compressor may take up to 3 minutes to turn on, or longer if it is too warm. Lower the room temperature to be below 90°F degrees. Clean the filters. Remove any obstructions in the exhaust hose and port. The unit must be vented. Minimize the size of the area to be cooled, i.e. adding a drop ceiling. Use more than one unit to cool the area, or use a larger unit. Close any open doors and windows. Remove or shut off additional heat sources such as radio equipment, servers, etc. Ensure room where unit to be operated is properly insulated. The unit may not work if the room temperature is above 90°F. Close curtains or pull down blinds, and minimize the direct sunlight into the room. Clean the filter and replace it if needed. Remove anything blocking the ports. Use heat function when temperatures rises above 50F. EdgeStar Portable Air Conditioner 22
