How to Properly Clean Your Air Conditioner in Summer

Wash the Filters Regularly

The filters are among the parts of an air conditioner that accumulate dust and dirt the fastest. During the summer, it is recommended to inspect and clean them every few weeks. On most models, the filters are easy to remove and can be washed with lukewarm water.

If they are heavily soiled, a small amount of mild detergent may be used. Before reinstalling the filters, make sure they are completely dry. Otherwise, mold and unpleasant odors may develop.

Don't Forget the Indoor Unit

It's not just the filters that need regular cleaning. Dust also builds up on the indoor unit's air vents, housing, and other surfaces over time. These areas can be cleaned with a soft, slightly damp cloth.

Avoid using abrasive materials or harsh chemical cleaners, as they may damage the unit's components.

Check the Condensate Drainage System

When an air conditioner operates, the condensation it produces is discharged through the drainage system. If the drain becomes clogged, water may begin leaking indoors. If you notice water stains around the indoor unit or detect unpleasant odors, it is advisable to contact a qualified technician to inspect and clean the drainage system.

How to Clean the Outdoor Unit

Before starting any cleaning, always disconnect the air conditioner from the power supply.

Remove leaves, twigs, and other debris from around the outdoor unit. The exterior can be cleaned with a soft brush or rinsed using low-pressure water. High-pressure washers are not recommended, as they can damage the condenser's delicate metal fins and other sensitive components.

Also, make sure there are no bushes, tall grass, furniture, or other objects blocking airflow around the outdoor unit. Proper ventilation is especially important during hot summer days to ensure efficient operation.

When Is Professional Maintenance Necessary?

Routine cleaning can easily be done at home. However, experts recommend having your air conditioner professionally serviced at least once a year.

During a maintenance visit, a technician checks the refrigerant level, inspects the internal components and drainage system, and ensures the unit is operating correctly. Regular servicing reduces the risk of breakdowns, improves energy efficiency, and helps extend the lifespan of the air conditioner.
