Check for Proper Fit: Ensure the filters fit properly within the unit to avoid gaps where dust can bypass the filter.

4. Frozen Evaporator Coils

Frozen evaporator coils can severely affect the cooling efficiency of your air conditioning unit. This issue typically occurs when airflow is restricted, causing the coils to become too cold and ice to form.

Causes of Frozen Coils:

Clogged Air Filters: Restricted airflow can cause coils to freeze.

Low Refrigerant Levels: Insufficient refrigerant can lead to coil freezing.

Blocked Air Ducts: Obstructions in the air ducts can reduce airflow.

Prevention Tips:

Regular Maintenance: Ensure regular maintenance checks to clean and inspect the evaporator coils.

Maintain Proper Refrigerant Levels: Have a professional check and top up refrigerant levels as needed.

Clear Air Ducts: Regularly check and clean air ducts to ensure unrestricted airflow.
