Why is My Ductwork Sweating During the Summer in Charlotte, NC?

September 19, 2018by Sophie The Dog

Have you noticed condensation on your air ducts and wondered whether you should be concerned? After all, it’s hot and humid in Charlotte which creates the right environment for condensation to form so you figure you shouldn’t worry, right? Charlotte summers do, indeed, create the right environment for condensation to form in a lot of places. The colder the air coming out of the ducts the more likely you’ll see condensation. Read on to find out when or if you should be concerned about sweating ductwork and what you can do about it.

It’s a Southern Thing in Charlotte

We live in the South and part of being a Southerner is sweat-dripping humidity. When warm, humid air meets cool air, water droplets form. This is condensation. Cool air runs through your ductwork in your attic or crawlspace and through the vents in your floor or ceiling where it meets warmer, humid air.

Occasional water droplets are not a cause for concern, especially when humidity levels are high, but when you notice persistent condensation around your vents, there are a couple things you will want to consider.

Mold and Mildew

Excessive amounts of condensation create the right environment for mold and mildew to grow. Mold and mildew may contribute to a range of health issues and damage to the inside of walls and ceilings. This can be expensive to repair and can be prevented.

Change Your Filters Regularly to Keep Your Ductwork Clean

Keeping your home cool and your air conditioner unit in good, working condition is very important to you. Taking care of your ductwork should be important as well. One way to keep air ducts clean is to replace your filters every month. Also, have a maintenance plan in place with a licensed HVAC contractor like Patterson Heating and Air Conditioning.

Make sure you check for leaky ducts by running your hands along the ductwork in your attic or crawlspace. If you feel any cold air, then you have a leak. You should call your Patterson to repair any leaks and check that you have the proper insulation around your ductwork.
