Extend the Lifespan of Your Air Conditioner
Malfunctions in air conditioners are a common issue during usage. Power outage and damage occur due to a large amount of dust clinging to the condenser, obstructing the cooling process and causing an overload on the air conditioner. This is also the reason why air conditioners quickly break down, reduce operational efficiency, and have a shortened lifespan.
Therefore, cleaning the air conditioner helps eliminate dirt, quickly detect malfunctions for timely repairs, avoiding incidents and electrical risks.

Save electricity
When the air conditioner is subjected to a large amount of dust and microorganisms existing in the device, it will reduce its cooling ability. Normally, the cool air from the air conditioner operates simultaneously with the machine startup, so the cold source dissipates quickly. However, when the device is not regularly cleaned, it will interrupt the operating process and consume more electrical energy, affecting the family's finances. Therefore, regular air conditioner maintenance will help save living expenses for the family.
Protect health
In the family living space, the air conditioner is considered the 'lung,' helping to purify and make the air more comfortable. Regular cleaning minimizes lingering odors in the room, providing a refreshing and pleasant atmosphere. As a result, people can avoid respiratory illnesses and eliminate bacteria harmful to human health.

Guide to cleaning the air conditioner at home
Power Off
To ensure safety during the cleaning process, disconnect the power supply connected to the air conditioner.
Clean the Evaporator Coil
First, you need to remove the fan by opening the air conditioner cover from bottom to top and taking out the dust filter.
Use a screwdriver to remove the screws securing the machine casing on the evaporator and check for any insects or debris inside. If present, clean it up to ensure better airflow of the machine's cold air.
Use an air conditioner cleaning bag to cover the entire body of the machine, avoiding water splashing onto the floor. Next, use a spray hose and cleaning spray bottle to clean the details on the evaporator.

Clean the Condenser Coil
For cleaning the condenser coil, simply remove the protective cover on the front, then spray and wash this protective cover layer. Next, clean the fan blades as well as the corners with dust buildup inside. Use a dry cloth to wipe the entire condenser coil until there is no water or moisture remaining.

Check Air Conditioner Refrigerant
In addition to air conditioner cleaning, you should regularly check the refrigerant to see if there are any leaks in the pipes using a specialized gas measuring tool. If you find leaks or the gas is running low, you can address it at home. Alternatively, you can contact reputable, authorized service providers for air conditioner refrigerant refilling to ensure gas quality.

Install Components for Air Conditioner
Make sure that the components of the condenser and evaporator are thoroughly dry before reassembly. The reassembly steps are performed in reverse order of disassembly.
- For the Evaporator: Install the dust filter back into its original position carefully to avoid damaging the mesh. Next, install the fan by closing the air conditioner cover from top to bottom. Use a screwdriver to tighten the screws on the machine body.
- For the Condenser: Install the protective cover on the front so that the branches align with each other.

Double-check the Machine's Operation
After reassembling the components for the air conditioner, plug in and start the air conditioner to see if the device is operating normally. If the machine runs smoothly and shows no unusual signs, it means you have completed the home air conditioner check and cleaning process.

Air Conditioner Cleaning Cycle
The air conditioner is a device that should be cleaned first when you plan to clean your house. Regular cleaning according to a cycle brings many benefits. However, the frequency of equipment cleaning also depends on the environment and usage throughout the year, as follows:
- For households: Air conditioners should be cleaned every 3 – 4 months (if opened and used daily) or cleaned every 6 months (if used only 3 – 4 days a week, with an average daily usage of about 6 – 8 hours).
- For companies and restaurants: Air conditioners should be cleaned after about 2 – 3 months of use, depending on whether the environment has more or less dust.
- For businesses, factories, production workshops: Air conditioners should be checked and cleaned monthly because in this environment, air conditioners operate almost continuously at a high frequency. However, for air conditioners operating in a dusty environment, it is better to call for cleaning services.
In addition, you should perform air conditioner cleaning when the following signs appear:
- Reduced cooling capacity.
- The machine's filter is covered in dust.
- Noises, automatic stops, constant temperature fluctuations.
- The air conditioner leaks water and emits an unpleasant odor.
- Poor air quality, causing a sense of breathlessness for users.
- Air conditioner refrigerant deficiency.
