Easy Steps to Properly Clean Your Overhead Air Conditioner at Home

Your overhead air conditioner may not be maintaining its cooling efficiency after some time. It's time to clean your overhead air conditioner. Do you know the correct and safe way to clean it? If not, let's take a look at the following article!

Detailed Guide on Cleaning Overhead Air Conditioners

Currently, various types of air conditioners are being introduced by manufacturers to serve specific usage purposes. Among them, the overhead air conditioner is a type of unit installed flush with the ceiling. It's important to note that this type of unit differs from wall-mounted air conditioners, which are attached to the wall.

Overhead Air Conditioners

Typically, overhead air conditioners have high cooling capacity, powerful cooling capabilities, and a variety of cooling functions. Currently, there is a wide variety of models, designs, and prices available on the market, allowing users to choose according to their home space and usage purposes.

Some notable benefits of overhead air conditioners include:

- Modern and elegant design, suitable for installation in any room space.

Overhead air conditioners feature a modern design

- Capable of producing strong airflow while ensuring quietness for the room space.

- The unit is capable of withstanding changes in weather conditions effectively.

- The unit features a self-oscillating mechanism and allows for multi-directional blade adjustment.

- Wide air outlets help spread air quickly and evenly to every corner of the room.

- Additionally, some models are equipped with air filtration capability, contributing to the protection of users' health.

Similar to other electronic devices, after a period of use, overhead air conditioners also accumulate a lot of dust, leading to decreased cooling efficiency. When the room is not cool enough, you will lower the room temperature, causing the compressor to continuously operate, resulting in unnecessary energy consumption. Therefore, to save electricity costs, you should clean overhead air conditioners regularly.

Furthermore, long-term accumulation of dust in the unit creates conditions for bacteria and mold to grow, causing air pollution inside the room. This directly affects your health. Therefore, to have a comfortable space, you must keep the air in the room clean by cleaning overhead air conditioners regularly.

Regularly clean overhead air conditioners to maintain clean indoor air

Heavy accumulation of dust will cause overhead air conditioners to operate frequently at high power levels. This prolonged condition can easily damage and reduce the lifespan of internal components, both the condenser and evaporator units. Therefore, regular cleaning of air conditioners is necessary to ensure longer device durability.

Before cleaning your overhead air conditioner, you need to prepare the following tools:

- Specialized air conditioner maintenance kit.

- Water-absorbing cloth for cleaning the evaporator coil.

- Air conditioner cleaning solution.

- Air conditioner disassembly tools: wrench, screwdriver, pliers,...

- Air conditioner refrigerant cylinder (compatible with the type of air conditioner you are using at home).

Tools for cleaning overhead air conditioners

Before cleaning the unit, you should check the current condition of the air conditioner to see if there are any faults or damages. If so, you should address them before cleaning the device. Additionally, you should also check for any gas leakage in the gas pipes. If there is a leak, you should promptly address it to ensure safety and cooling efficiency of the unit.

Pre-cleaning inspection of the unit

- Step 1: Remove the outer protective cover and the device's faceplate to begin cleaning. When removing the signal eye and control keypad, you need to be careful to avoid water splashing and short circuits.

- Step 2: Remove the water collecting tray for cleaning. This part is quite long and has a foam component, so you should handle it carefully to avoid breakage.

- Step 3: Remove and clean the squirrel cage of the unit. Then, you should also lubricate the bearings to ensure smoother operation of the squirrel cage.

- Step 4: Clean the circuit board thoroughly and use a dryer to dry it.

- Step 5: Place a specialized cloth evenly at the 4 corners of the unit to collect dirty water during the cleaning process. Then, use a high-pressure water nozzle to clean the evaporator coil. If the dirt is too stubborn, you can use some detergent.

- Step 6: During the cleaning process, you should spray in the direction from top to bottom to avoid bending the cooling fan blades. Remember to clean both the inside and outside of the unit to push out all the dirt.

- Step 7: For the drain pipe, you should scrub it thoroughly to remove all the accumulated residue.

- Step 8: After rinsing, dry the components and reassemble them in their original positions.

Cleaning the Evaporator Coil

- Step 1: Tidy up the area around the condenser coil (if any).

- Step 2: Remove the outer casing of the condenser coil to clean the circuit board and starter. Then, use plastic bags to cover these two components to prevent water damage.

- Step 3: Use a specialized cleaning machine to clean the entire surface of the condenser coil. Be careful when cleaning the fan to avoid deformation.

- Step 4: Remove the heat sink fan to inspect, clean, and lubricate the fan motor.

- Step 5: Check the sockets, wire connections to the block, pressure relay, phase loss protection device,...

- Step 6: Dry and reassemble the components back to their original positions.

Cleaning the Condenser Coil

After completing the cleaning process, you should let the unit rest for a period of time to ensure it is completely dry. Then, proceed to test the unit and check if it operates normally. If any abnormal signs are noticed, stop the unit to inspect, identify the cause, and promptly rectify it.

Cleaning overhead air conditioners requires the performer to have specialized knowledge and necessary skills. Therefore, for safety reasons, you should contact professional and reputable air conditioner cleaning services for assistance.

Above are detailed instructions on how to clean overhead air conditioners safely and effectively. Hopefully, this information will help you observe and supervise the cleaning process more conveniently. Remember to clean overhead air conditioners regularly to maintain their cooling efficiency and save energy!
