Impact of Dirty Ductwork on Indoor Air Quality

Posted in Air Duct, Commercial, Residential, Tips & Advice

Dirty air ducts can lead to dust, debris, pet hair, and other particulate matter clogging up the ventilation system in your home or office. This not only affects your health by making breathing more difficult (due to increased allergens), but also contributes to less efficient heating or cooling in your home. Today, Power Vac of Ottawa technicians go more in-depth about the consequences of dirty ductwork and why air duct cleaning is essential.

Do Dirty Air Ducts Contribute That Much to Indoor Air Pollution?

Air ducts work by moving air from one location to another. So, in short, yes. Uncleaned air ducts can contribute quite significantly to indoor air pollution and contamination.

Now, to be fair, unclean air ducts aren't the only thing that can contribute to poor indoor air quality. Other factors include poor ventilation, humidity control issues, and a lack of insulation, just to name a few. However, a good duct cleaning can still do wonders for your indoor air quality.

How Unclean Air Ducts Affect Air Quality?

The following are just some of the ways unclean air ducts can cause indoor air pollution.

Unclean Air Ducts Allow Pollutants in from Outside

When your air ducts are dirty, they'll allow more pollutants to enter your home, putting you and your family at risk of inhaling unclean air. Uncleaned ducts allow pollutants from the outside to enter our homes and be inhaled. This is especially true during the summer, when windows are typically open and you can't close all of your air ducts.  

Dirty Air Ducts are Sources of Contaminants

Dust and other contaminants from dirty ducts can spread allergens throughout a home or office.

It is critical to clean your ducts and filters on a regular basis in order to maintain healthy indoor air quality in your home. This can significantly reduce the number of contaminants you breathe in, while also improving air quality in your home or office.

Dirty Air Ducts are Sources for Mould

Dirty ductwork can also contribute to the growth of mould and bacteria. These micro-organisms can further worsen indoor air quality and pose health risks, especially for individuals with respiratory conditions.

What Are the Health Impacts of Dirty Air Ducts?

Below, we'll list some of the consequences unclean air ducts can have on your health.


If you have asthma, the quality of your indoor air is critical. Unclean air ducts not only contribute to indoor air pollution, but also increase the risk of asthma attacks.

Allergens or irritants such as dust mites, pollen, and mould spores can cause asthma attacks. When dust or dirt particles are not filtered out of your air system, they can enter your lungs and cause inflammation, making it difficult to breathe normally.

Eye Irritation

If you notice that your eyes are more irritated than usual, it could be due to clogged air ducts. This is because dust particles in the air increase your chances of getting an eye infection.

Sinus Issues

Sinus issues can also be a result of clogged air ducts. When dust and allergens circulate in the air, they can irritate the sinuses and lead to congestion, sinus pressure, sinus infections and even pneumonia.
