How Your Ducts Become Dirty

How clean are the ducts in your home? If you haven’t scheduled regular professional cleaning for them in two years or more, you might be in for an unpleasant surprise if you reach down inside one of the vents with a handheld mirror to get a view of the interior. No matter how clean a home you try to keep, your ducts will get dirty over time to the point that the dust, dirt, and other debris inside can have a negative impact on your indoor air quality and lower the performance of your heater and air conditioner, even leading to damaging them.

We’ll explain how your ducts get this way to help you understand why regular, professional duct cleaning in Marietta, GA is essential for maintaining clean air and a working HVAC system. To schedule quality ductwork cleaning, contact our air quality specialists at Cool Air Mechanical today.

How a Home’s Ductwork Becomes Dirty

Although a cleaner house will slow down how fast dust and dirt gather inside a ventilation system, no amount of cleanliness can stop the eventual build-up. The reason for this is that the ventilation system is constantly circulating the air inside your home, and any dirt and dust inside the rooms will eventually find their way into the ductwork. Since the ducts are sealed along their length to prevent the loss of air pressure, they are basically dust traps: as dirt and other particles enter the ducts, they become trapped inside with no way to escape (except to get blown back out into your air or dragged into the AC). Dust that you sweep up will fly into the air and into the return vents, joining the rest of the dust. Homes have such effective air sealing on them today to make them more energy efficient that there are few places to which the dust inside your house can escape.

You can ventilate your home with open doors and windows, but this 1) will not reach into and clean out the ducts, and 2) may bring in more foreign particles which will then become trapped in the house and circulated through the ventilation with the rest of the dust.

There is another potential threat to the interior of your ducts: mold. Mold spores can enter the ventilation system and take hold and start to grow in humid weather. If your home suffers from unusually high humidity, this can become a serious issue.

However, you have help available for all these problems: the indoor air quality experts at Cool Air Mechanical.
