What Is a Duct?

These ducts are the conduits that supply your home with cool or heated air. They are connected to your AC or HVAC system. They are crucial in helping your AC work properly and contribute to improving the quality of the air in your home.


There are three different ductwork variants and all of them have their respective advantages and possible drawbacks. These are:

  • Sheet metal ducts: These are usually the least prone to harboring mold and the most durable. 
  • Fiberboard ducts: Usually the least expensive, these two-layered ducts (fiberglass and foil) are well insulated but can harbor mildew and mold. Also, rough fiberglass can compromise airflow a bit.
  • Flex ducts: Extremely flexible, lightweight, and inexpensive. Flex ducts are immensely popular, even though, less sturdy than metal systems.

How Do They Work?

In an HVAC system, the air goes through a cycle, with negative pressure in the ducts that sucks the air in passing it through the filters. The air is either cooled or heated and sent back to your rooms.

Low Air Quality

When dust is collecting in your house, and when you see your loved ones sneezing more often, your AC ductwork might need cleaning because the air quality is compromised in your home. 

AC Ductwork Tear and Wear

Ductwork installation might seem like a simple process, but moving air is takes a toll on the system. This means that even a high-quality system is prone to issues over time. Knowing how to prepare for air duct cleaning and knowing the telltale signs of potential problems can improve the lifespan of your system and can help you with keeping your home nice and cool.

Before we get started, you should know that different duct types will have different expiration dates. Naturally, metal ducts are the sturdiest, but even they are susceptible to problems.

As the system gets older, these are the most common problems that may arise:

Corroded and Leaky Ducts

Regular air duct cleaning is necessary to avoid corrosion, as moisture can also get into the ducts. Humid spaces are more susceptible to letting moisture in, and sagging ducts may also have this problem as condensation may gather in the dips of the duct lines.

Dirty and Clogged Ducts

Loose connections, irregular maintenance, duct inspections, holes, and even dirty indoor air can lead to clogged air ducts that will compromise airflow and will make the overall problem even worse. To avoid this, aim for first-class ductwork installation services and work with a professional team for regular maintenance.

Mold and Mildew

Knowing how to prepare for air duct cleaning starts with making sure there’s no way of moisture entering the ducts. When moisture manages to get into the system, mold will appear over time. This won’t cause any physical problems in the system, but it will compromise air quality which can lead to potential health problems.

The supply vents blow the spores from the mold in the house, which can also damage the walls and your favorite pieces of furniture.

If you suspect that mold may be collecting in your ductwork, hiring a professional as soon as possible is essential.

Pest Problems

Apart from mold and debris, sometimes pests are those that compromise your ductwork from working properly. When the ductwork installation process was previously carried out poorly, disconnected parts, tears, and wear can serve as openings for bugs and rodents that can create nests in the duct system and multiply. This can compromise airflow leading to unwanted noises, unpleasant smells, and a myriad of other concerns in your home.
