What Health Concerns Are There If You Don’t Keep Your Air Ducts Clean?

Dirty air ducts can lead to poor indoor air quality, with dust, allergens, bacteria, pollutants, pet hair and other airborne particles circulating around your home. These harmful particles can lead to a range of health problems, particularly in children, older people and those with a history of allergies.


Asthma is a long-term health condition that causes a variety of respiratory problems, including wheezing, coughing and tightness in the chest. Serious complications can occur if the condition is not adequately controlled. Asthma can be aggravated by dust mites, pet hair, pollen and other airborne particles, leading to a worsening of symptoms and an increase in acute asthma attacks. Keeping your air ducts clean and free of debris is essential for reducing air pollutants in your home.

Respiratory Problems

Respiratory problems, such as breathlessness, wheezing, a persistent tickly cough or a tight chest, can be caused or aggravated by poor indoor air quality. Mold spores, dust mites and pet hair circulating around your home can irritate your respiratory system, particularly if you already have an underlying medical condition that affects your lungs. Chronic lung disease and acute respiratory conditions, such as bronchitis, can be aggravated by poor air quality.


Pet hair, dust mites and other allergens can cause a whole range of symptoms, including skin conditions, sinus problems, eye irritation, respiratory conditions, tiredness and digestive problems. Hayfever, also known as allergic rhinitis, is caused by pollen and other pollutants, which can enter your home through open windows, on your clothing and on your pets.

Sinus Headaches

Sinus headaches are caused by inflammation of the sinuses, which leads to painful throbbing around the sinuses and face. Mold spores, pet hair, pollen, dust mites and other airborne pollutants can all cause sinus problems and inflammation, particularly if you have a history of allergies. Keeping clean air circulating around your home and reducing indoor allergens is one of the best ways to prevent chronic sinus problems and the associated sinus headaches.


Bacteria, viruses and airborne contaminants circulating around the home can be a serious health risk, particularly for babies, children, older people and those with some health conditions, such as diabetes, asthma and heart disease. Clean air is essential for helping to reduce the spread of airborne infections. Airborne contaminants can also cause skin infections and long-term skin complaints.

General Health

The human immune system provides a powerful defense against infection and disease. However, if the immune system is continually fighting off allergens and pollutants, it can leave you feeling tired, run down and unwell, increasing the risk of chronic health problems, such as headaches, digestive problems and irritable bowel syndrome (IBS). Reducing indoor pollutants takes some of the pressure off your immune system.

In addition to improving air quality in your home and helping to prevent health problems, cleaning your air ducts helps to increase the efficiency of your heating and cooling system, reducing the long-term costs of your system.
