Correct way to service a window AC

What is the correct way to service a window AC?

Window ACs are a common and effective way to provide cooling during the summer season in homes and offices. However, to maintain optimal performance, periodic and proper servicing is crucial. Without proper maintenance, AC cooling capacity decreases, power consumption increases, and the machine's lifespan decreases. In this article, we'll explore the proper way to service a window AC so you can keep it in good condition for a long time.

1. Why Window AC Servicing is Important

Timely servicing of a window AC has many benefits, such as

Improved cooling

Energy savings

Longer life of the machine

Relief from bad odors or dust

Protection from germs and bacteria

2. Preparations Before Servicing

Before starting AC servicing, some important preparations must be made:

First, turn off the power supply. This is essential for safety.

If you need to remove the AC from a window or wall, have a helper help you.

Have the necessary tools ready, such as a screwdriver, brush, water sprayer, and cleaning solution.

3. How to Clean the Outdoor AC Unit

Cleaning the exterior surface of the window AC is the first and most important step.

Clean off dust and grime with a brush or dry cloth.

Then, rinse the surface with a damp cloth or water spray.

Pay special attention to ensure that dirt does not accumulate in the AC grill and fins, as this can obstruct airflow.

4. Proper Cleaning of the AC Filter

The AC filter is the most contaminated part because it filters the air.

Open the AC's front cover and remove the filter.

Wash the filter by mixing the cleaning solution with lukewarm water.

Gently remove dirt with a brush and let it dry completely.

Replace the filter only when it is completely dry.

5. Cleaning the Aluminum Fins and Coils

Cleaning the fins and coils is crucial for cooling quality.

Accumulation of dust or fungus on them negatively impacts AC performance.

Clean these parts with a soft brush or fin cleaner.

The fins are very delicate, so avoid applying excessive pressure.

6. Check and Clean the Drainage System

Window ACs have a drainage pipe or a drain hole through which water drains.

If this becomes blocked, water can accumulate inside the AC, causing a leak.

Clean this hole with a thin wire or brush and ensure that water can drain easily.

7. Fan Blade and Motor Care

Cleaning the fan blades improves airflow.

Remove any dust from the blades and wipe them with a damp cloth.

A light lubricant should be applied to the motor to ensure smooth rotation.

If there is any problem with the wiring or noise of the motor, seek professional help.

8. Check Electrical Connections and Wiring

All wiring should be thoroughly checked.

Loose connections or burnt wires can be dangerous.

Also, have a technician check the insulation and earthing.

Also, check that the power button, remote, and other controls are working properly.

9. Reinstalling and Testing the AC

After all cleaning and testing is complete, reinstall the AC.

Carefully fit the unit into the window.

Tighten all screws and reconnect the power connections.

Turn on the AC and check its cooling, noise level, and water drainage.

10. Servicing Frequency and Tips

Window ACs need to be serviced every 3 to 6 months, especially before the onset of summer.

If your area is very dusty, clean the filters monthly.

Professional service once a year is also beneficial, especially if there are problems like gas leaks, poor cooling, or noise.

Conclusion

Regular and proper window AC servicing not only increases the life of your unit but also controls your electricity bill. By following the methods mentioned above, you can clean and service your AC yourself at home and enjoy cool air in every season. If you encounter a more complex problem, it's best to seek the help of a professional service engineer.
