Air conditioners (ACs) are essential devices for maintaining indoor comfort, especially during the hot summers. However, like any other electronic device, ACs can also experience problems over time. Don’t worry, many AC problems can be fixed without calling a technician, as long as you know the right steps. This article will discuss how to fix your AC with some easy-to-follow tips and tricks.

1. AC Not Cooling? Check the Temperature and Mode Settings

The first problem that is often encountered is an AC that is not cooling. If your AC is not providing optimal cooling, the first step is to check the temperature and mode settings.

Check the Temperature Settings: Make sure the temperature setting on your AC remote is low enough, around 16-20°C to ensure effective cooling.

Check the AC Mode: Make sure your AC is set to “Cool” mode. Sometimes, ACs can be set to “Fan” or “Heat” mode which reduces its ability to cool the room.

2. Clean the AC Filter

A dirty AC filter can block airflow, which ultimately makes the AC unable to cool the room optimally. For this reason, clean the AC filter regularly.

How to clean the AC filter:

Turn off the AC and unplug the power cord for safety.
Open the AC cover and remove the air filter.
Wash the filter with running water and mild soap. Make sure the filter is completely dry before reinstalling it.
With a clean filter, the AC air flow will be smooth, and the AC will work more efficiently.

3. Check the AC Drain

The AC also has a drain to drain condensation water that forms during the cooling process. If this drain is clogged, water can spill into the room, or the AC can stop working properly.

• How to clean the drain:
• Turn off the AC and unplug the power cord.

Check the drain under the AC unit, make sure there is no dirt or foreign objects blocking the water flow. Slot Online
Use a cleaning tool such as a small brush or spray low-pressure air to clean the drain.

4. Check the Condenser and Evaporator

The AC condenser and evaporator are two important parts of the cooling system.  The condenser is usually located outside the room, while the evaporator is inside the AC unit. Both of these components can become dirty and hinder the cooling process.

• How to clean the condenser and evaporator:
• Turn off the AC and unplug the power cord.
• Clean the condenser with a soft brush or spray low-pressure air to remove dirt or dust that sticks.
• For the evaporator, make sure there is no dirt or dust covering this part.
• If you find it difficult to clean this part, you should ask for help from a professional technician.

5. Check the AC Fan

A dirty or damaged AC fan can disrupt AC cooling. Check if the AC fan is working properly, and make sure there are no foreign objects blocking the fan movement.

How to check the AC fan:

Turn off the AC and unplug the power cord.
Check the fan part and make sure there is no dirt blocking the fan rotation.
If the fan sounds noisy or does not rotate smoothly, you may need to replace it or ask a technician for help.
6. Check the Freon Drainage System
If your AC is still not cold even though it has been cleaned, the problem could be with the freon. Freon is a liquid used in the AC cooling system. If the freon level is low or there is a leak, the AC cannot cool the air properly.

How to check freon:

Check for leaks in the freon line. Usually, freon leaks cannot be detected with the naked eye, so you need a professional technician to check and refill the freon.
7. AC Gives Off an Unpleasant Smell?
The unpleasant odor coming from the AC is usually caused by the growth of mold or germs inside the unit. To solve this problem, you need to thoroughly clean the inside of the AC.

How to deal with unpleasant odors:

Turn off the AC and unplug the power cord.
Clean the filter and the inside of the AC using a special cleaning fluid for AC.
Make sure the AC is dry before turning it back on.
8. Call a Technician If the Problem Is Not Resolved
If you have tried all of the steps above but the AC is still having problems, it may be time to call a professional technician. A technician can perform further inspections and fix more complex problems, such as freon leaks or damage to the AC's internal components.

Conclusion
Fixing a problematic AC doesn't always require a large expense or a technician call. By performing routine checks and maintenance such as cleaning the filter, checking the water drain, and maintaining other components, you can optimize the performance of your AC and avoid bigger problems in the future. However, if the problem persists, it doesn't hurt to
