  If your Honeywell Portable air conditioner runs but isn't cooling, consider these possibilities: Check if a door or window is open, and make sure the window or door is closed. A dirty air filter can also cause this, so clean the air filter. Ensure the exhaust hose is properly reinstalled. If the temperature setting is too high, reduce temperature setting. Also, make sure that air outlet or intake is not blocked by removing blockage. If the room exceeds recommended size, move unit to smaller room. Finally, if there are a large size or number of windows, cover windows with curtains or blinds.
