How to Handle Water Around Air Conditioning Vents


Having water or condensation around your air conditioning vents might not seem like a big deal, but it can lead to some serious problems. This vent moisture can cause problems that affect your homeandrsquo;s structural integrity and your own health. Find out more about why this moisture builds up.

Reasons for Vent Moisture

Moisture around air conditioning (A/C) vents can happen for different reasons. You might not have enough insulation around your ducts, which leaves them more vulnerable to having condensation build-up. There might also be too much moisture in the air inside your home, resulting in high humidity levels and water around your A/C vents. Other possible causes include clogged condensate drain lines and air leaks around these vents.

Problems with Vent Moisture

Why is this type of moisture bad for your home and your health? Having moisture present increases the risk of the following problems:

  • Mold growth: mold thrives in damp or moist conditions, which could lead to a serious mold problem when you have vents and ducts covered with water. Some types of mold can cause health issues, especially if you have asthma or another respiratory ailment.
  • Structural damage: water around A/C vents in your attic can leak onto your ceilings. Over time, this can weaken these structures and cause them to rot and eventually collapse when the damage is severe enough.
  • Poor insulation: moisture around vents and ducts can also affect the insulation in your home. When this insulation is damp, it isnandrsquo;t able to insulate your home as well as it normally should.

What to Do About Moisture Around A/C Vents

In order to prevent vent moisture, youandrsquo;ll need to know why itandrsquo;s happening. Depending on the cause, you might need to have your ducts better insulated, fix air leaks, repair clogged condensate drain lines or reduce the amount of moisture in the air inside your home. Itandrsquo;s best to let a professional determine the cause of this problem and handle it for you.
