Air Duct Condensation: Causes and Simple Remedies

There are a few things no home or building owner wants to deal with when it comes to the HVAC system, and several of these involve the presence of moisture in places it shouldn’t be. One great example here, and one that many have dealt with in the past: Condensation building up in or around the air ducts that are meant to transport air to and from various parts of the structure. 

At Green Line Heating & Air, we’re happy to help with a wide range of HVAC services for our Herriman clients, including themes like air duct cleaning and several others that speak to the health of these important components in your system. What are some reasons why condensation in or around your ductwork may be taking place, and what can be done about it? This two-part blog series will discuss everything you need to know.

Why Condensation Forms Around Ducts

There are a few different reasons for condensation forming around your air ducts, but the most common and well-known is a major temperature difference between the air inside the duct and the air outside of it. If the temperature inside the duct is much colder than the temperature of the air around it, this can cause water vapor to condense and form droplets on the surface.

There are other potential causes as well, such as if there’s a leak in the duct itself that’s allowing humid air from outside to seep in. There are certain cases where a lack of insulation around the duct can cause this same issue. There are even situations where too much humidity in the home or building is contributing to the condensation.

Whatever the reason for your condensation, it’s important to take steps to address it as soon as possible, as this moisture can lead to a number of secondary problems. Our next few sections will discuss some methods for limiting or preventing condensation around your ducts, either on your own or with the help of our HVAC professionals.

Insulate the Ducts

In many cases, condensation around the ducts is caused by a lack of insulation, so this is one of the first places you’ll want to start if you’re having this issue. By adding insulation, you can help keep the temperature inside the duct consistent, which will in turn limit or prevent condensation from forming.

There are a few different ways to insulate air ducts, so you’ll want to consult with our team to determine the best method for your particular setup. We can also help with the installation process to ensure it’s done correctly and that you’re getting the most out of your insulation.
