The answer to 'how to maintain air conditioner' is to perform regular maintenance tasks like cleaning the air filters, clearing debris around the outdoor unit, and scheduling annual professional tune-ups. Proper maintenance helps your AC system run efficiently, extend its lifespan, and avoid costly breakdowns.
Start by checking and cleaning the air filters every 1-3 months, depending on usage and environment. Dirty filters restrict airflow and make the system work harder, reducing efficiency. Gently vacuum or rinse the filters to remove dust and dirt. Replace disposable filters as needed.
