If your Asami Air Conditioner isn't cooling or heating as expected, here are a few things to check: * Make sure that the air intake or outlet of the indoor or outdoor unit is not blocked and remove any obstruction. * Adjust the temperature, fan speed, and wind direction using the wireless or wired controller. * Ensure doors and windows are closed and that curtains or louvers are drawn to block direct sunlight. * Reduce the number of heat sources in the room. * Clean the filter if it's blocked with dirt.
