How To Get Rid Of The Cough From Air Conditioners





Coughing can be a nuisance, especially when it's persistent and triggered by your air conditioning. The air quality in your home can play a significant role in the development of respiratory issues and coughing. In this article, we discuss the possible causes of an AC cough and explore some cures that can help alleviate the symptoms. We also look at the benefits of using air purifiers and humidifiers to improve air quality in your home.


What's Causing Your Cough?

There are a few things to consider when trying to determine what's causing your cough. First, it's important to know that when the air is dry or cold--and especially if you have certain conditions like asthma and COPD--the moisture in your lungs can't be expelled as easily. This means that if you're feeling a little under the weather, lowering humidity levels may make your symptoms worse.

Dirty air conditioner filters could be to blame.

According to several sources, a dirty air filter can lead to dust and dirt buildup that can trigger allergies and other respiratory problems, including coughing. 

When the HVAC filter is dirty and maxed out, it can no longer capture air particles, and these particles pass through the filter, cycling back through the HVAC and into the air you breathe, lowering the air quality. 

If you are experiencing coughing due to a dirty air filter, it is recommended to change the filter or add a humidity machine to the room. In case the culprit is mold or extra dusty ductwork, calling in a professional to clean it properly is advised.

Leaking Air Conditioners could be the issue

Air conditioners can contain refrigerants such as Freon, which can be harmful when leaking. Freon can cause respiratory issues such as coughing, shortness of breath, and lung inflammation when inhaled. 

In addition to refrigerant leaks, air conditioners can also harbor mold and other allergens that can worsen respiratory issues and cause coughing. 

It is recommended to have air conditioning units regularly inspected and maintained to ensure they are functioning properly and not leaking any harmful substances into the air.

Cures for an AC Cough

If you're suffering from an AC cough, there are several cures that you can try.

  • One of the most important things to do is to replace the air filter regularly, as dirty filters can lead to irritation and coughing. Additionally, turning on the TCL Auto-clean feature can help keep your unit clean and free of debris.
  • It's also important to maintain your air conditioner, ensuring that it's in good working order and free of leaks.
  • To prevent coughing, try using your A/C less frequently and turning on comfortable cooling mode to maintain a comfortable humidity level.
  • Consider buying a new air conditioner as well, which can help relieve respiratory problems brought on by dry or stale indoor air by introducing outdoor air that is rich in oxygen and suitable for humidity.

Consider an air purifier or a humidifier

Installing air purifiers and humidifiers can be an effective way to improve air quality and potentially alleviate coughing caused by air conditioning.


Air purifiers work by removing allergens, pollutants, and other harmful particles from the air, which can reduce the risk of respiratory issues and coughing. Some air purifiers also have UV-C lights that can kill germs and bacteria in the air, which could be beneficial for people with weakened immune systems.


Humidifiers, on the other hand, add moisture to the air, which can help to alleviate dryness and irritation in the throat and respiratory system caused by air conditioning. Dry air can also make it easier for airborne particles to travel, potentially worsening respiratory issues.


It is essential to note that while air purifiers and humidifiers can be beneficial for improving air quality and reducing coughing, they are not a cure-all solution. It is recommended to have regular maintenance and cleaning of both the air filters and air conditioning system to promote better air quality.
