Five Air Quality Hazards Found in Your Ducts

Do you know what’s in your air ducts? If you’re like most homeowners, you’re probably unaware of just how much could have found its way into your ducts over time. While you may not realize it, the truth is your ductwork is home to a number of air quality ruining hazards that could cause a number of issues in your home ranging from foul odors to asthma attacks and allergic reactions. On this blog, we’ll explore some of the most common things you can find in your air ducts and demonstrate why it’s a good idea to have your ducts cleaned regularly by a professional Palm Beach County duct services team.

Dirt & Dust

Perhaps the most common thing in your air ducts? Dust. Microscopic particles of dirt that find their way through your air filter and spread throughout your duct network. Dust is everywhere, gets everywhere, and is particularly difficult to clean out unless you have the right cleaning tools. The good news is that your air filter should be able to screen out the majority of it, but the bad news is that dust which settles in your ducts could stay there for years, even with regular usage of your HVAC system.

Mold & Mildew

Mold requires three things to form: a source of moisture, a source of food, and protection from potentially lethal radiation. It’s not uncommon for the inside of your air ducts to fulfill these three conditions, and as a result mold and mildew can grow inside your ducts fairly easily. Once mold takes root, it takes about three days to show up, and once it does, getting it out can be a real nuisance. Mildew is similar, and produces that familiar musty smell that’s pretty much unmistakable. While many people mistake it for mold, the truth is the two often come together so odds are if you have one, you probably also have the other.


Bacteria can build up in your air ducts with ease. Airborne bacteria is everywhere, and it gets into your air ducts with ease, especially when air isn’t being forced through the ducts by a fan. While most bacteria won’t necessarily harm you, high concentrations of it can develop into issues that can cause respiratory problems, allergic reactions, asthma attacks, and plenty of other issues to boot. To make matters worse, combined with the effects of mold bacteria could make you ill, which means it’s best to get rid of it quickly.


Pollen is fairly common in air ducts, particularly in high-pollen places or homes which have a high number of indoor plants. Pollen levels tend to peak around springtime, when most plants are flowering and pollen is plentiful, and levels then reduce throughout the year until they’re at their lowest during winter. High-wind seasons can also kick up an abundance of pollen, which means more could find its way into your home, and thus into your air ducts, where it could be recirculated throughout your home.

Pet Hair & Dander

Do you have a dog or a cat? If you’re like most American homes, the answer is “yes,” and could even be “multiple.” While our furry, four-legged best friends are without question members of our family, they could be leaving pet hair and dander floating through the air in your home. In most cases, this hair gets trapped in your air filter, but the occasional small strand can squeak through, especially if your filter has been clogged up and not changed for some time.

Pet dander is even more commonly found in air ducts, and is one of the leading causes of allergy and asthma triggers. When it gets into your air ducts, it can cause allergic reactions in every room in your home, even if you’re doing everything you can to contain it to a limited area.
