What are Air Ducts and How do They Work?

Air ducts are a network of tubes that distribute heated or cooled air throughout a building or home. They are typically made of metal or insulated material and range in size from small, flexible ducts to large, rigid ductwork. The air that circulates through the ducts is filtered with your HVAC unit's air filter to remove pollutants, but over time, the ducts themselves can become a breeding ground for mold, bacteria, and other harmful substances.

The Risks of Dirty Air Ducts

Dirty air ducts can have a significant impact on indoor air quality, causing respiratory issues, allergies, and other health problems. In addition, dirty ducts can also increase your energy bills and reduce the efficiency of your HVAC system because of build-up and blockage in the ductwork.

Mold in Air Ducts

Mold is a common problem in air ducts and can cause serious health problems if left untreated. Mold can cause respiratory issues, including asthma and allergies, and can even trigger life-threatening reactions in people with mold sensitivities. When your HVAC system runs and sends heated or cooled air to rooms in your building or home, spores can be spread from room to room inside of ductwork.

Bacteria and Viruses

Bacteria and viruses can also thrive in air ducts, especially in moist or damp conditions. These harmful substances can circulate through the air in your home, putting you and your family at risk for respiratory infections and other illnesses.

Dust and Debris

Dust and debris can accumulate in air ducts over time, reducing the air quality in your home and potentially causing respiratory issues and allergies. Not only is the dust unsafe to breathe, but it also can result in a consistent accumulation of dust around your home on furniture, blinds, or on the ground.

How to Ensure Safe and Clean Air Ducts

To ensure the air in your home is safe and clean, it is important to have your air ducts inspected and cleaned regularly by a professional HVAC company.

Here are a few tips to keep your air ducts in top condition:

Regular Inspection and Cleaning

Having your air ducts inspected and cleaned every three to five years is the best way to keep them in top condition. During this process, a professional will remove any mold, bacteria, dust, and debris that may have accumulated in the ducts. They will also inspect your ductwork and make recommendations to make your HVAC system more safe and more efficient with a product like aeroseal.

Proper Ventilation

Proper ventilation is crucial for preventing mold and other pollutants from accumulating in air ducts. Make sure your HVAC system has adequate ventilation, and be sure to have any leaks or cracks in the ducts repaired promptly. Without ventilation humidity and moisture can build up and lead to a breeding ground for mold.

Regular Filter Changes

Regularly changing your HVAC system's filters is one of the easiest ways to maintain the air quality in your home. Be sure to change your filters every three to six months, or more often if you have pets or allergies.


Air ducts are an essential part of every building's HVAC system, but they can also pose a significant health risk if not properly maintained. By following the tips outlined in this article, you can ensure that the air you and your family breathe is clean and safe.
