Air conditioners, or AC units, are common household appliances used for cooling and regulating indoor air temperature, especially during hot summer days. Regularly cleaning your air conditioner can bring about unexpected benefits. Let's explore how to clean your AC unit at home in this article.
Why is it Important to Clean Your Air Conditioner at Home?
When using an air conditioner, it's essential to have a regular cleaning routine. This not only ensures the efficient functioning of the appliance but also prolongs its lifespan and safeguards the health of your family.
Extending the Lifespan of Your Air Conditioner
Common issues like malfunctions are frequently encountered during air conditioner usage. Power interruptions and damages occur due to excessive dust accumulation on the condenser coil, hindering the cooling process and causing overloading. This leads to rapid breakdowns, reduced operational efficiency, and shortened lifespan of the air conditioner.
Therefore, cleaning the air conditioner helps eliminate dust and quickly identify any damages for timely repairs, avoiding electrical incidents and risks.

Save Electricity
When an air conditioner accumulates a large amount of dust and microorganisms, its cooling efficiency decreases. Typically, the cool air is released simultaneously with the machine startup, ensuring rapid cooling. However, if the device is not regularly cleaned, it disrupts the operation process and consumes more electricity, affecting the household finances. Therefore, regular air conditioner maintenance helps save on household expenses.
Protect Health
In the family living space, the air conditioner is considered the 'lung,' helping to regulate fresher and more comfortable air. Regular cleaning minimizes existing odors in the room, bringing a refreshing and pleasant air. As a result, people can avoid respiratory diseases and eliminate bacteria harmful to humans.

Guide to Cleaning Your Air Conditioner at Home
Turn Off Power
To ensure safety during cleaning, switch off the power connected to the air conditioner.
Clean the Evaporator Coil
Firstly, you need to remove the air circulation fan and then open the air conditioner cover from bottom to top, 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 them up to improve air circulation.
Cover the entire machine body with an air conditioner cleaning bag to prevent water from splashing onto the floor. Then, use a spray nozzle and cleaning spray bottle to clean the components on the evaporator.

Clean the Condenser Unit
For cleaning the condenser unit, simply remove the protective cover from the front, then spray and wash this protective cover layer. Next, clean the fan blades and any dusty corners inside. Use a dry cloth to wipe the entire condenser unit until there is no water or moisture remaining.

Check Air Conditioner Gas
In addition to cleaning the air conditioner, you should regularly check the air conditioner gas to see if there are any leaks in the pipes using a specialized gas gauge. If you detect leaks or the gas is running out, you can troubleshoot at home. Alternatively, you can contact reputable, authorized gas refill services at stores to ensure gas quality.

Install Air Conditioner Components
Ensure that all components of the condenser and evaporator are thoroughly dried before reinstalling. The installation steps are performed in reverse order of removal.
- For the evaporator unit: Carefully install the dust filter back into its original position to avoid tearing the mesh. Next, install the air circulation fan and cover the air conditioner from top to bottom. Use a screwdriver to tighten the screws on the machine body.
- For the condenser unit: Install the protective cover on the front so that the branches align with each other.

Double-check the Machine's Operation
After reinstalling the air conditioner components, plug in the power and start the air conditioner to see if the device operates normally. If the machine runs smoothly and there are no signs of abnormalities, it means you have completed the home air conditioner check and cleaning process.

Air Conditioner Cleaning Cycle
The air conditioner is an appliance that needs to be cleaned first when you intend to clean the house. Regular cleaning according to a cycle brings many benefits. However, the frequency of cleaning the device depends on the environment and frequency of use throughout the year, as follows:
- For households: Air conditioners should be cleaned every 3 - 4 months (if used and opened daily) or cleaned every 6 months (if used only 3 - 4 days a week, with an average daily usage of 6 - 8 hours).
- For companies and restaurants: Air conditioners should be cleaned after about 2 - 3 months of use, depending on the amount of dust in the environment.
- For businesses, factories, workshops, manufacturing plants: Air conditioners should be checked and cleaned monthly because in these environments, air conditioners operate almost continuously at high frequencies. However, for air conditioners operating in dusty environments, it is better to call a cleaning service.
Additionally, you should perform air conditioner cleaning when you notice the following signs:
- The cooling capacity decreases.
- The air conditioner filter is heavily covered in dust.
- It emits noise, automatically stops, and experiences frequent temperature fluctuations.
- The air conditioner leaks water and emits unpleasant odors.
- The air quality becomes poor, causing discomfort for users.
