  If your Mitsubishi Electric Air Conditioner isn't heating or cooling effectively, start by checking the air filter. A dirty or clogged filter can significantly reduce airflow, so cleaning it may solve the problem. Also, ensure the temperature is properly adjusted. Make sure there's enough space around the outdoor unit for proper ventilation. Check if the indoor unit's air intake or outlet is blocked. Finally, ensure all doors and windows are closed to prevent drafts.
