How to Prevent Condensation in Your Air Ducts

Condensation can be a somewhat common problem with ac system ducts. Long term condensation causes numerous problems with your air conditioning system. Condensation can regularly be viewed as water drops gathering on the outside of air conditioning ducts and vent openings. It can also form small water pools on the flooring and other places in your home in severe cases. This results in health hazards and very costly repairs if not addressed quickly and properly.

Why Does Condensation Form in Air Ducts?
Main triggers for condensation happening in your a/c ducts include the temperature level differences in between the air outside and inside the duct, incorrectly sealed AC ducts, and lack of insulation around these air ducts.

Ductwork sweating can also be exacerbated by aspects like:

  • Stopped up ducts
  • Excessive Humidity in the home or attic
  • Unclean air filters

What Causes Air Vents to Drip?
Condensate drain issues cause water to drip from your AC’s ductwork. The function of the condensate drain system is to gather wetness removed from the air and dispose it into a drain. Water leak can be triggered when:

  • The drip tray is dripping
  • The condensate tube is blocked with dirt, algae, or minerals
  • The evaporator coil, which freezes on scorching days, starts to thaw

Are There Cases Where Too Much Insulation In a Home or Building Can Cause Condensation?
In some cases too much insulation can cause condensation. This is due to the fact that insulation warms the indoor location of your building. Normally, warm air holds more moisture and makes the inside of your building more humid. Temperature level modifications permit the structure to become cooler in the evening. This prompts the air inside to cool off and release moisture, which results in condensation.

Effectively Insulating The Ducts Themselves
Wrapping your a/c ductwork is an effective method to prevent condensation. Duct wrap has a foam insulation inner layer and a foil outer layer. Easily cover it around the air conditioning duct and attach with duct tape near the joints.

Can You Minimize Humidity in your HVAC System?
Here are some techniques to stop condensation on air ducts:

  • Attempt to reduce the humidity level in the air near the air ducts. You can opt for a dehumidifier if that helps to decrease the condensation.
  • Instead of metal, select fiberglass or other insulating materials for your ductwork. In case you have metal ducts, ensure they are appropriately wrapped with fiberglass insulation.
  • Repair leaking ducts as early as possible.
  • Unclog any ducts that are limiting air flow and have them cleaned regularly.
  • Routinely clean your air filters and be sure to change them when every 3 months.
