That means the cooling coil will not be adequately cooled; in fact, it might start to become warmer the longer we run the AC.
Should a window AC be level?
Many people mistakenly believe that air conditioners should be pitched down, slightly out of level, to help them drain condensate. Actually, an air conditioner should be installed so it is level. These appliances are designed so that condensate collects below the fan and runs into the slinger ring.
