Sweaty Ductwork: What Causes It & How to Deal With It


You know you’re dealing with something serious if you find condensation on your HVAC system’s ductwork. This issue can compromise the comfort of your living space and cause damage to other components of your equipment. Fortunately, Premier Comfort is here to address this issue. 

Read on to learn what causes sweaty ductwork and how to deal with it. 


Common Causes of Sweaty Ductwork

Condensation in ducts mainly occurs due to a temperature difference between the interior and exterior. Water beads can start forming on the outer surface of the ductwork if the air inside the ducts is significantly colder than it is on the outside.


When your HVAC system doesn’t drain water properly or gets too cold, condensation will form on the ducts. Water will also accumulate in your equipment if it’s not getting rid of air moisture effectively or if you have drainage problems. This issue can cause not only condensation, but also leaks and ice formation on various parts of your HVAC system. 


How Do You Deal With This Issue?

Metal ducts can’t insulate themselves. Since this material is an excellent heat conductor, the exterior surface of your ductwork reflects the temperature of its environment. It’s the same with the air that flows through it. Hiring a heating and cooling contractor to insulate your ducts can help prevent them from sweating. 


Addressing leaks in your ductwork is another way to deal with and prevent sweating. Sealing gaps, holes and cracks will significantly reduce the likelihood of condensation. Another thing that can help you avoid sweaty ductwork is using a dehumidifier. You’ll greatly benefit from this if your ductwork is in your attic or crawl space.
