In most cases, it has been noticed that people don’t feel good when the air conditioner is constantly running. Folks are facing sore throat or a nagging cough. There are a few more things that you need to know, for example, why does this happen? Before going for the solution, we will discuss the causes.

Cause of Coughing due to Air Conditioner

There can be different causes of coughing. We do not intend to give you medical advice, but when it comes to air conditioning, we can help you to determine the actual culprit for your coughing. There are a few different factors that initial this coughing:

  1. Cold And Dry Air

The major cause of coughing is cold and dry air. Now, what is this dry air? Well, in simple terms, dry air without humidity or moisture content is dry air. Air conditioners remove humidity and cool the air, thus can lead to dry air. This happens when people are exposed to cold air, leading to coughing variant asthma. 

Even though you don’t have any symptoms, you can still suffer from cough variant asthma. If you see that the cough is leading to congestion and less throat irritation, it could be due to the humidity. Generally, the air conditioner creates a thin balance in your home, and any environmental change can directly affect your health. 

  1. Dirty Air can Make You Cough

Another primary cause of coughing is mould which normally grows in a damp environment. Thus, the air conditioner collects standing water leads to a mouldy mess. In better terms, it could cause air conditioner lung problems. These different types of moulds or fungus growth can even cause hypersensitivity pneumonitis. 

It mainly occurs when you haven’t replaced the air conditioner on time. Thus, collect more dust, dirt, pet hair, mould and bacteria etc., which will blow back instead of getting removed. Particularly those who already have a history of difficult breathing or a history of respiratory illness, then they have a high chance of getting infected. 

  1. Leaking Air Conditioning

It might be possible that the air conditioner is the source of a leak. In general, the air conditioner removes the moisture from the air and drains water from the drainage passage. If there is any leak, clog, or other problem, the water redirects back into your home. 

This water becomes the root cause of mould and bacterial growth, and it can even lower the air quality, thus raising the humidity level. So, both issues can lead to coughing. Therefore it is very important to inspect the air conditioner and look for ways to prevent moisture. Thus, seeking help from professionals will be beneficial.
