As a rule, an unpleasant odor from the air conditioner appears after using it for some time. Often, even with this problem, the climate control equipment works properly, but all the benefits of using an air conditioner are reduced to zero, and the question also arises about the safety of inhaling such air.

Causes

Among the most common reasons why there is an odor from the air conditioner in an apartment, there are three main ones:

• Accumulation of dust and bacteriaThe split system constantly circulates air, and with it various bacteria, mold spores and other microorganisms. The moist and warm air inside the equipment is an excellent environment for their reproduction, so after a while there become a lot of “unwanted guests”. Together with the air, microorganisms and mold again enter the room in high concentrations. It is their accumulation that can cause an unpleasant odor, and it is not safe to inhale such air.
• Lack of siphon in the drainage systemSometimes the condensate from the air conditioner is discharged into the sewer. With this solution, it is necessary to install a special siphon; the use of a curved tube is not effective. In the absence of a siphon, the unpleasant odor from the sewer enters the air conditioner and then spreads throughout the room.
• Concentration of odors from the roomMost modern air conditioners do not absorb air from the street, but circulate it inside the apartment. That is, the air from the room constantly passes through the split system, thereby accumulating all the aromas that are inside. As a result, an unpleasant odor appears when the air conditioner is turned on. Most often, the cause is a high concentration of formaldehyde, which can be contained in plastic and other items found in the house. You can especially notice this phenomenon if you purchased new furniture.

Troubleshooting

Sometimes, in order to solve the problem of an unpleasant odor from an air conditioner, it is enough just to completely dry the system so that the moisture inside evaporates and bacteria and microorganisms are unable to multiply.

If the problem is not solved, it is necessary to carry out antibacterial treatment of the air conditioner using special products, often produced in the form of a spray, or use modern antibacterial filters or ionizers.
