  If your Mitsubishi Electric Air Conditioner isn't cooling well, start by cleaning the filter, as reduced airflow can occur when it's dirty or clogged. Also, check the temperature adjustment and adjust the set temperature. Ensure there's plenty of space around the outdoor unit, and that the indoor unit's air intake or outlet isn't blocked. Finally, make sure no doors or windows have been left open.
