How Do Air Ducts Get So Dirty?

Posted by Lisa Pixley

Dirty air ducts can have a major effect on your health and on the way that your air conditioner works. When the ducts are dirty, there’s a chance that the air from your blower fan can kick up some of the dust and debris and send it back to the air in your home, aggravating your allergy symptoms or making things worse if you have asthma or an immune system disorder. Additionally, airflow may be restricted through the system due to friction from the buildup in the pipes, which can lower AC and heating efficiency.

But Doesn’t the Air Filter Help?

You do have an air filter in your AC system to help eliminate particles from the air you breathe. This is typically located in the return grille of your AC system, the part where air first enters as a blower fan behind the filter sucks air into the system. That means that your air is filtered before it ever reaches the system.

However, that doesn’t mean that all of the dust and particles get trapped in the filter. The filter’s main purpose is to protect the air conditioning and heating units from the potential damage of incoming debris. Particles that are so small they are tough to see with the naked eye often are not of concern when it comes to this. So the filter might not be effective enough with trapping tiny dust particles and other allergens.

So Where’s All This dust Coming From?

There is likely a lot more dust in your home than you realize. You keep a clean house, you vacuum often, and you pay attention to surfaces like the tops of ceiling fans. But no matter what you do, you cannot stop the dust entirely from getting into your home in the first place.

The dust is composed of skin flakes, pet dander, insects, the roads outside and the wind that kicks it up, and all around your home. Dust is everywhere, but air duct cleaning helps to keep it under control.
