When the air filter is plugged, it restricts the airflow into the air conditioner. This reduced airflow can cause the evaporator coils to freeze up, blocking the airflow even further and preventing the AC from blowing cold air.
Additionally, a plugged air filter can put strain on the AC's blower motor, causing it to overheat and fail prematurely.
It is important to regularly check and replace your air filter to prevent these issues and maintain the efficiency and longevity of your AC unit.
