Why is my Mitsubishi Electric Air Conditioner not cooling or heating well?
- D
  Daniel Wall DDSAug 19, 2025
  Your Mitsubishi Electric Air Conditioner might not be heating or cooling well due to several reasons. Reduced airflow from a dirty or clogged filter is one potential cause, so clean the filter. Check the temperature adjustment and adjust the set temperature. Also, ensure there is plenty of space around the outdoor unit and that neither the indoor unit's air intake nor outlet is blocked. Finally, check if a door or window has been left open.
