The central air conditioner smells of smoke. What happened?

The central air conditioner smells of smoke mainly because there are fine particles such as smoke, dust and pollen in the air, which will gradually accumulate in the air conditioner over time. If these fine particles are small enough, they will enter the air filter, leading to the blockage of the filter screen and incomplete filtration, which in turn will lead to the odor at the air outlet of the central air conditioner, including the smell of smoke.

In addition to the particulate matter accumulated in the air filter, it may cause the air outlet of the central air conditioner to smell, and the long-term humid environment may also cause the filter screen or other parts of the central air conditioner to smell musty. However, in the process of use, if you encounter irregular use, such as opening the window for a long time, it will also lead to the accumulation of a large number of odor sources in the central air conditioner.

The following measures can be taken to solve the odor problem of central air conditioning:

First of all, the filter screen of the central air conditioner should be cleaned and replaced regularly. The filter screen can filter out most of the particles in the air. Replacing or cleaning the filter screen in time can ensure the normal air filtration effect, thus reducing the possibility of odor generation.

Secondly, keeping the indoor environment dry, especially in rainy season, using dehumidifier or keeping indoor ventilation, and regularly disinfecting and cleaning the inside of the air conditioner to reduce the chances of bacteria breeding are also ways to reduce the generation of odor.

Finally, you can also use an air purifier or air freshener to remove residual odor and eliminate indoor odor. However, when using the freshener, we should be careful not to use it too frequently and excessively, so as not to affect human health.
