Why is my MrCool Universal MDU18048060 Inverter not cooling or heating well?

If your MrCool Inverter isn't cooling or heating properly, several factors could be the cause. First, check if the air inlet and outlet are blocked; clear any obstacles to ensure proper ventilation. Make sure the temperature setting and fan speed are appropriate for your needs. Adjust the air louvers to direct airflow correctly and close any open doors or windows. Reduce heat sources in the room, and use curtains to block direct sunlight. If the filter is dirty, have it professionally cleaned.
