Similar to other devices, an air conditioner achieves optimal performance when regularly cleaned and maintained. Mold in air conditioners is a common issue if you neglect its hygiene. So, how do you identify if your AC has mold, and what are the effective remedies? Let's find out in this informative article!
Mold in Air Conditioners and Effective Solutions
1. Signs of Mold Presence in Air Conditioners
Not always can we visibly detect mold in air conditioners unless it has appeared on the outer surface of the device. Particularly, air conditioners are often mounted at a height, making it challenging to spot mold with the naked eye. However, you can still identify mold in the air conditioner through the following signs:
1.1. Cold air emits a foul smell
This is a relatively easy sign for you to recognize mold in the air conditioner. When the AC is running, you will notice an unpleasant smell accompanying the cold air flow. This odor is most noticeable right after you turn on the air conditioner.

1.2. Respiratory patients show more severe symptoms
If there is someone with respiratory issues in the family, you will notice an increase in symptoms such as coughing, sneezing, wheezing, etc., occurring more frequently over time. Even when they spend time in an air-conditioned room, they may experience more headaches or a sore throat. At this point, you should consider checking whether there is mold inside your air conditioner.
Although not a definitive sign of mold in the air conditioner, it serves as a reminder to regularly clean and maintain the equipment.

2. How to check if the air conditioner has mold
Before conducting the check, it is advisable to wear a mask to avoid inhaling dirt and accumulated particles into the body. Typically, mold can appear in black, white, green, orange, pink, or yellow colors. Recognizing mold by color helps prevent confusion with regular dirt. Sometimes, mold may also appear as black dust clinging around the air vents.

If you don't see mold on the outside, it doesn't mean it's not present deep inside the device. Therefore, use a flashlight to make it easier to identify.
To identify accurately, you can follow the steps below:
- For wall-mounted air conditioners: Firstly, disconnect the power and remove the front cover. Then, take out the filter mesh and check for any signs of mold. If not visible, use a flashlight to carefully observe deep inside the unit for signs of mold growth.
- For central air conditioning systems: This type of AC system is more complex, so avoid dismantling any parts. Instead, identify mold by using a flashlight to peer into the device. Pay close attention to areas such as the fan, air vents, or ducts, as these are common spots for mold growth. Also, don't forget to check the outdoor condenser unit.
3. Effective Solutions for Mold in Air Conditioners
Once you detect mold in the air conditioner, it's crucial to temporarily stop using the device and address the issue as soon as possible. Continuing to use the AC will spread mold and various pathogens throughout the room.
If the wall-mounted air conditioner has a significant amount of mold, deeply embedded and scattered in various components, professional cleaning services are the only solution. However, they may not completely eliminate all mold inside the AC. If you want a mold-free air conditioner, opting for a complete replacement is a viable option.
If mold has only appeared in the filter mesh, you can easily handle it yourself. Before cleaning, wear a mask and gloves to limit exposure to dirt. Here are the steps to clean mold on the filter mesh:
- Step 1: Disconnect the power to the AC, then remove the front cover and gently take out the filter mesh. Next, use a soft-bristle brush to clean the dirt and mold clinging to this filter mesh.

- Step 2: Prepare a large basin and add a cleaning solution with a ratio of 1:10, then dissolve them.
- Step 3: Place the entire filter mesh into the solution and let it soak for at least 10 minutes.
- Step 4: After soaking, thoroughly rinse the filter mesh and let it dry completely before reinstalling it in its original position. Note that before reinstalling the filter mesh, clean the external surface of the evaporator to eliminate any remaining mold.
- Step 5: Run the air conditioner for a test. If the foul odor persists after about 15 - 30 minutes, contact an air conditioner cleaning service for inspection and assistance.
If your household uses a central air conditioning system and you notice mold, contact the warranty center for support. These systems are highly complex, and handling them yourself is not advisable.
As you can see, dealing with mold in the air conditioner is challenging and can be costly, especially when it has formed extensively. Therefore, scheduling regular air conditioner cleaning is essential to minimize mold formation. Additionally, don't overlook cleaning the outdoor condenser unit, as it is a common breeding ground for mold.
