How Do You Stop Condensation on Ductworks?
Ducts are like any part of a home in that they can be affected by many different things, including changes in seasons. When you get to the warmer months of the year and switch your HVAC system to the air conditioner or cooling mode, you may notice what's referred to as "ductwork sweating." This doesn't necessarily mean you have a serious HVAC problem. However, duct condensation is something you'll want to address sooner rather than later.

Reasons for Ductwork Condensation

Condensation is the process of water vapor turning into liquid form. It's what happens if you take a cold can of soda out of the fridge on a hot summer day. The same concept applies to your air conditioner and ductwork. When your air conditioner is running, your ducts are carrying cold air. Therefore, exposure to hot, humid air causes a clash of hot and cold that results in liquid water on your ducts. Ductwork sweating may also be caused by, exasperated by, or related to:
  • Poor or insufficient insulation
  • Excess moisture within your indoor environment
  • Dirty or clogged heater or air conditioner filters
  • Ductwork that's blocked in one or more sections
Condensation on ductwork could also be due to a leak. If your ducts are leaking, your air conditioner won't be as efficient as it could be, which could further contribute to or worsen condensation. Lack of sufficient HVAC maintenance is another possible factor, although it's more likely to apply if you have an older home.

Should You Be Concerned about Ductwork Condensation?

If you're only occasionally noticing condensation on your ducts when you run your air conditioner, there's not much to be concerned about. You'll still want to be mindful of any condensation you see, though. Persistent ductwork sweating, on the other hand, can contribute to an assortment of issues. Some of these include:
  • Mold or mildew issues
  • Am uptick in allergy or respiratory symptoms
  • Water damage

What Are Possible Air Conditioner Duct Sweating Solutions?

Wrapping your ducts is one possible solution. If you're going to do this to stop condensation on your ductwork, use fiberglass insulation if you have metal HVAC ducts. You want insulation materials to fit well as you wrap them around, but don't wrap them too tightly. Doing so will reduce the ability to minimize duct sweat. Additionally, lowering the humidity around your ductwork can be helpful. How you do this will depend on where your ducts are located. For instance, if they're in the attic, make sure your attic is insulated and well ventilated to lower humidity levels. You may also be able to reduce HVAC duct condensation issues by:
  • Getting your ducts unblocked if there are blockages
  • Regularly changing your HVAC filters
  • Having leaking ductwork repaired
  • Getting your air conditioner checked to make sure it's operating correctly and efficiently
