Air Conditioner Maintenance Tips: It is common for people to question a mechanic's work just days after getting their AC serviced. They often complain that cooling efficiency dropped again quickly, feeling their money was wasted; however, most are unaware that the primary cause isn't the mechanic's error, but rather the dust and dirt that re-accumulate within a short time. Regular cleaning not only significantly improves cooling performance but also helps curb excessive electricity consumption and extends the machine's lifespan. The good news is that you don't need to call a mechanic repeatedly for this simple maintenance; you can enhance your AC's performance by following the easy and smart methods outlined in this article...

**First, Clean the Front Grille and Screen**

If dust has accumulated on your AC's front panel or screen, airflow can be obstructed, directly impacting cooling efficiency.

**How ​​to clean:** Before starting, turn off the AC and unplug it for safety. Then, carefully open the front panel; in most AC units, this is secured with clips or screws.

Next, remove accumulated dust using a soft brush, vacuum cleaner, or dry cloth. If there is significant dirt, you can use a cloth dampened with a mixture of lukewarm water and a little dish soap, or a brush, to clean it gently. Afterward, allow it to dry completely before reattaching it.

**Cleaning the AC Filter is Crucial**

If you want optimal AC performance, cleaning the filter should be a top priority.

**What to do?** To clean the filter, first turn off and unplug the AC. Then, open the front panel of the indoor unit and remove the filter.

**Step 3:** Remove the accumulated dust from the filter using a vacuum cleaner or a soft brush. If the filter is heavily soiled, you can wash it using lukewarm water and a mild detergent.

Ensure you do not dry the filter in direct sunlight, as this could warp its shape. Reinstall it only after it has dried completely.

**Cleaning the indoor coil improves cooling**

If cooling does not improve despite these measures, the issue might lie with the indoor coil. The evaporator coil is a crucial component of the AC; dust accumulation on it can impair cooling efficiency.

How do you clean the indoor coil? First, switch off the AC's power supply. Then, remove the front panel and the filter. Gently remove loose dust using a soft brush or a vacuum cleaner. Next, apply a commercially available coil cleaner foam and let it sit for about 10 to 15 minutes.

The foam loosens the dirt. Afterward, you can clean it with a gentle stream of water or use a no-rinse cleaner. While you are at it, clean the blower fan and the drain tray as well. Do not rush; turn the AC back on only after everything has dried completely.

**Don't overlook the outdoor unit's coil**

Many people assume that cleaning only the indoor unit will ensure better cooling, but dirt can also accumulate in the outdoor unit.

What should you do?

First, turn off the power and clear away any leaves, dust, or debris accumulated around the unit. Then, clean the condenser coil and fins using a soft brush or a vacuum cleaner. If necessary, apply coil cleaner spray and rinse gently with water after 5 to 10 minutes.

Be careful not to bend the fins during cleaning, and strictly avoid using high-pressure water jets. Also, ensure water does not come into contact with electrical components.

**The self-clean feature can also help**
Many modern AC models come equipped with a self-clean or 'i-Clean' feature. In such models, the internal cleaning process can also be activated by pressing this button.

How often should it be cleaned?
Many people open the unit every week hoping for better cooling, but experts warn that doing so can be detrimental. Specialists recommend cleaning the AC filter every 15 to 30 days. If you live in a dusty area, you may need to perform this task more frequently.

Follow these simple tips for better cooling.
To enjoy your AC effectively alongside regular cleaning, you should also make some adjustments to your habits...
Keep the AC temperature between 24°C and 26°C.
Keep the curtains closed during the day to minimize heat entry.
Clean the drain line periodically.
