Cleaning your AC filter is the single most impactful 10-minute job you can do for your air conditioner. A clogged filter restricts airflow, forces the compressor to work harder, raises your bill by 10–15%, freezes the indoor coil, and pushes dust and allergens back into the air your family breathes.
How often should you clean it?
During heavy summer use (May to September in Islamabad), clean the filter every 2 weeks. In moderate weather, once a month is enough. If you live near a construction site, busy road, or in a dust-prone area like parts of Rawalpindi or PWD, clean it every week.
What you'll need
A soft brush or toothbrush, a tap with running water, a few drops of mild dishwashing liquid, and a clean dry cloth. That's it — no chemicals, no special tools.
Step-by-step
1) Switch off the AC at the wall socket. 2) Open the front panel of the indoor unit. 3) Slide out the two mesh filters carefully. 4) Tap them gently over a bin to remove loose dust. 5) Rinse under cold running water from the back side. 6) For greasy buildup, brush with a little soapy water and rinse clean. 7) Shake off water and let them air-dry completely in shade. 8) Slide them back, close the panel, and run the AC on fan mode for 10 minutes.
When to call a professional
Filter cleaning handles dust, but it doesn't touch the evaporator coil, drain pan, or fan blower. These need a deep chemical service every 6 months. AF Tech Fix's single-visit deep service costs less than a single month of inflated electricity bills caused by a dirty system.
