Why Cleaning Your AC Filter Matters
A clogged AC filter is one of the most common reasons your air conditioner stops cooling efficiently. Dust, dirt, and debris accumulate on the filter over time, blocking airflow and forcing the compressor to work harder. This not only reduces cooling performance but also drives up your electricity bill by 15-20%. In dusty cities like Jaipur, where summer temperatures regularly cross 45 degrees Celsius, a clean filter can make the difference between a comfortable home and a sweltering one.
What You Will Need
You do not need any special tools for this task. Keep a soft brush or old toothbrush handy, along with mild liquid soap or detergent, a bucket of lukewarm water, a soft dry cloth, and optionally a vacuum cleaner with a brush attachment. The entire process takes about 10-15 minutes and should be done once every two weeks during heavy usage months like April through September.
Step 1: Turn Off the AC and Unplug It
Safety comes first. Switch off your air conditioner from the remote and then turn off the power supply at the plug or MCB. Wait for a minute before you begin working on the unit. This ensures there is no residual electrical charge and the internal fan has stopped spinning completely.
Step 2: Open the Front Panel and Remove the Filter
For split ACs, gently lift the front panel of the indoor unit upward until it clicks into the open position. You will see one or two mesh filters sitting in a frame. Carefully slide them out. For window ACs, remove the front grille by unscrewing or unclipping it, then pull the filter out. Handle the filters gently as they can be fragile, especially in older units.
Step 3: Clean the Filter
If the filter has light dust, simply use a vacuum cleaner with a soft brush attachment to remove the debris. For heavier buildup, soak the filter in a bucket of lukewarm water mixed with a few drops of mild detergent for 10 minutes. Then gently scrub both sides with a soft brush. Rinse under running water until the water runs clear. Never use hot water or harsh chemicals as they can damage the filter mesh.
Step 4: Dry and Reinstall
Shake off excess water and let the filter air dry completely in a shaded area. Do not place it in direct sunlight as UV rays can make the plastic brittle over time. Once fully dry, slide the filter back into its slot, close the front panel, and power the unit back on. You should immediately notice better airflow and cooler air coming from your AC.
When to Call a Professional
If cleaning the filter does not improve performance, or if you notice the filter is torn, warped, or has a persistent odour even after washing, it may be time for a replacement or a deeper AC service. At Vishwakarma Aircon, we offer comprehensive AC servicing that includes deep coil cleaning, gas pressure checks, and drainage line clearing — everything beyond what a simple filter clean can address.
