What is the cause of the air conditioner blowing a sour smell?

“Turn on the air conditioner and it smells sour”

The cause of the unpleasant odor is due to the accumulation of dust and dirt inside the air conditioner. Those dirt can be of the following types:

Mold

The air we breathe every day consists of many different tiny particles. Mold spores are also one of them. These spores are sucked into the air conditioner along with the air, using the moisture and organic substances inside the air conditioner as food to grow. We may think that the cause of the air conditioner smelling sour is mold.

House dust

In addition to mold, pollen, house dust or other bacteria that exist in the form of tiny particles floating in the air are also the causes of bad odors in the air conditioner.

Room smelly and dirty

 If your room is dirty or there is smoking in the room, odor particles in the room can be sucked into the air conditioner and accumulate inside causing a bad smell.

Method to remove air conditioner odors immediately

To prevent bad air conditioner odors, high pressure washing to remove mold, which is the main cause of unpleasant odors, is extremely important. However, it takes a lot of time to call a cleaning company and almost no cleaning company can respond on the same day.

Suddenly there are guests coming to the house or there is no time to clean... in such urgent cases, what should we do to deodorize the air conditioner?

In this section, we will explain temporary treatment methods to remove air conditioner odors.

Use deodorizing spray for air conditioners

You can buy deodorizing sprays for air conditioners at home appliance centers. These deodorizing sprays contain antibacterial ingredients that weaken the activity of mold and bacteria. Spray on the air conditioner while the machine is running, the active ingredients penetrate inside to help eliminate mold and eliminate odors. However, these deodorizing sprays also contain ethanol, which can dissolve styrene, which is a component of the drain, so special attention should be paid when using it. Furthermore, those who are allergic to chemical compounds should also pay special attention because they contain ingredients that cause allergic symptoms.

Use aromatic essential oils

Using aromatic essential oils to suppress the bad smell coming from the air conditioner is also a very effective temporary solution. After removing the dust filter and cleaning, spray aromatic essential oil on it and reinsert it into the air conditioner. Thus, the air sucked into the air conditioner also contains aromatic essential oils and the air blown out from the air conditioner will also be improved.

Open the window and let the air conditioner run at 16 degrees for a few minutes

Air conditioners have a characteristic that when using the air conditioner, the heat exchanger will be cooled and the inside of the air conditioner will also have a low temperature. People use this feature to weaken mold activity inside the air conditioner and help eliminate unpleasant odors. In case you feel an unpleasant odor from the air conditioner, reduce the temperature to 16 degrees, increase the wind level to the highest and let the air conditioner run for a few minutes. Doing so will reduce mold activity and reduce unpleasant odors. Additionally, to eliminate odors that accumulate in the room, open windows and doors completely to allow quick air exchange.

Air conditioner cleaning method to prevent odors

The cause of bad air conditioning is tiny particles flying in the air. To keep these small dust particles from sticking inside the air conditioner, regular cleaning is extremely important.

In this section, we will explain regular cleaning methods to prevent bad air conditioner odors.

Clean the dust filter screen

 The air conditioner filter is a very important part that helps filter dust particles in the air and prevent dirt from accumulating inside the air conditioner. Please remove and clean it once a week. Furthermore, once a month, use a brush and neutral detergent to wash, helping to maintain better dust filtering properties.

Clean the ventilation door

 Periodically clean the air blowing part called the ventilation door. Clean the gaps between the louvers and the area around the exhaust fan using a damp, wrung-out cloth and a disposable stick like a chopstick. The wind direction adjustment blade is very fragile, so clean it gently. Cleaning tools made from melamine sponges and disposable chopsticks are also very useful, so give them a try.

Clean the room

Even if the air conditioner is clean but the room is dirty, there is still a risk of odorous ingredients accumulating inside the air conditioner. Regularly clean your home several times a week by vacuuming floors and using wipes to remove dust build-up on furniture and interiors.
