Weak Airflow or Reduced Cooling/Heating

Often caused by dirty coils, filters, or fan components.

Unusual Noises or Vibrations

Grinding, clicking, or rattling can signal internal component wear.

Hot or Cold Spots

Inconsistent temperatures may indicate dirty or failing indoor units.

Higher Energy Bills
