  Jason SmithAug 23, 2025
  If your Mitsubishi Electric Air Conditioner isn't heating or cooling effectively, start by cleaning the filter, as reduced airflow from a dirty or clogged filter could be the culprit. Also, check the temperature settings and adjust as needed. Ensure that the outdoor unit has enough space around it for proper ventilation. Finally, make sure no doors or windows are left open, as this can impact performance.
