Cleaning Air Ducts for Better Indoor Air Quality

As dust, debris and other particles accumulate inside heating and air conditioning ducts, they can negatively affect indoor air quality.


As dust, debris and other particles accumulate inside heating and air conditioning ducts, they can negatively affect indoor air quality. Regular air duct cleaning removes these contaminants, improving the efficiency of your HVAC system and the air you breathe.

The buildup of contaminants in ducts occurs gradually over time. Dust, pet dander, pollen, hair, skin cells, mold and bacteria stick to the interior surfaces (1). Chemical off-gassing from materials inside the ductwork also pollutes the air (2). If left unaddressed, this accumulation of particles and pollutants gets pulled through the ventilation system into occupied spaces.

Fortunately, proper air duct cleaning can effectively. Nonetheless, having your ducts professionally cleaned by an HVAC company ensures a thorough job . Professionals have the right equipment, chemicals and expertise for maximum contaminant removal.

Some key benefits of regular duct cleaning include:

Improved indoor air quality:

First, by removing particles and pollutants from ducts, trapped contaminants are no longer recirculated into the building. This results in cleaner, healthier air throughout.

Reduced allergens and irritants:

Also, allergens like dust mites, pet dander and mold can build up inside ducts, triggering reactions in sensitive individuals. Thorough duct cleaning captures and removes these allergens.

Increased HVAC efficiency:

In addition, a buildup of dust and debris on the interior surfaces of ductwork causes airflow restrictions and lowers HVAC performance. Professional cleaning restores airflow and efficiency.

Lower energy bills:

Furthermore, when HVAC ducts are clean, the system can run at optimal efficiency. This means the unit has to work less hard to properly heat and cool spaces, saving energy and lowering utility costs.

To maximize the benefits of duct cleaning, have it performed every 1 to 5 years, depending on conditions. Indicators that it’s time for a cleaning include:

Visible dust or debris around supply registers after running the HVAC; noticing an increase in allergens indoors; and a decrease in heating/cooling capability or air circulation.

In summary, regular air duct cleaning is an important maintenance task for anyone concerned with indoor comfort and health. Provided by an experienced HVAC contractor, duct cleaning can improve air quality throughout, benefiting your whole family.
