Are Unclean Air Ducts Responsible For Lung Infection?

If you think about it, air ducts are responsible for providing us with clean air. However, if the ducts are not properly maintained and cleaned regularly, then they can actually become a breeding ground for bacteria and viruses. 

This can lead to lung infections such as pneumonia, bronchitis and even tuberculosis. In this article, we will examine how unclean air ducts may lead to lung infections hence how crucial is it hire professional duct cleaning service.


Allergens, dust mites, mould and mildew, are just some of the contaminants that can make their way into your ducts. 

When you breathe in these particles as you sleep or work throughout the day, they can cause respiratory problems like asthma or even lung cancer. This is why it’s important to hire professional duct cleaning regularly to prevent any harm from occurring.

When cleaning your air ducts, make sure that they are completely dry before turning on your heaters or air conditioners again so as not to create moisture buildup within them, which could lead to mould growth and other health hazards such as allergic reactions due to exposure over time (especially if someone suffers from allergies).

Irritant Builds Up in the Ducts

If you don’t clean your air ducts regularly, the resulting buildup can harbour bacteria and mould. 

This can be problematic because the situation only worsens over time, so even if you start cleaning your system now, it may not be enough. If you have young children or people with compromised immune systems in your home, this is even more important.

The most common way that these airborne contaminants enter your body is by breathing them in while they’re still airborne around the house (which happens to be a lot). 

However, some of those nasty byproducts can also get into your lungs when they settle on surfaces like furniture and walls before being inhaled later on down the road when someone touches them again—or even years later during another cleaning cycle!

Dust mites are microscopic insects that live in bedding, furniture, carpeting and upholstered furniture. They thrive in warm, humid environments and attach to humans when they sleep or sit on contaminated surfaces.

Dust mites feed on skin scales and other organic matter they find while crawling around your home. These allergens can trigger an immune response that causes symptoms like sneezing and coughing as well as asthma attacks.

Dust mites are very common allergens found in homes throughout the world—in fact, it is estimated that 90 per cent of homes have these tiny arachnids present at any given time! The most common dust mite is called Dermatophagoides pteronyssinus; however, there are many different types, including Dermatophagoides farinae, which prefer warmer climates than those preferred by D pteronyssinus but still thrive at room temperature (71 degrees Fahrenheit). 

These two types typically live near each other but not necessarily together unless conditions allow for this (elevated humidity levels). 

Other common household pests may also harbour these tiny critters, including cockroaches or even mice if they’re close enough proximity—although these pests tend not to be born with them, so they aren’t considered vectors like cats/dogs would be if infected themselves by bites from another animal carrying them.


Viruses can cause flu and other respiratory infections. They are very small and can pass through ducts easily. Viruses live for a long time, even in cold temperatures. They are not destroyed by disinfectants, so they could still be present in the ductwork after cleaning.

While there is no evidence that unclean air ducts can make you sick, there is some evidence that the viruses in them may cause illness if you have an existing respiratory condition or weakened immune system (such as diabetes).


A lot of people don’t realise that the air in their homes can be just as dirty as the water they drink. Many of us are breathing in dust mites, moulds and other allergens that cause irritation to our lungs and sinuses.
