What to Do About Moisture Around Your Air Conditioner Vents

If you start to notice water stains on the ceiling around your vents or even feel the vents and they are wet to the touch, you have a problem that needs to be addressed promptly. What you are seeing is condensation forming inside of your vents. Similar to a can of soda, the air inside your ducts is cold, but the air around it is hot enough to form condensation inside your vents. Not only can this cause water damage, water in your vents can also result in mold growth that can be even more difficult to deal with.

At JR Perkins Heating & Cooling, we often explain to our customers why this happens in the first place. Condensation inside of your air conditioner vents will typically manifest for two reasons:

1. The duct boot, or the part where the duct connects to the vent, is possibly not properly sealed. This means that air is leaking out and meeting warm air. Not only does this cause moisture, but it effects energy efficiency as well.

2. The second cause is because your ducts are not properly insulated. Insulation of your duct work serves to not allow the hot air outside of the properly sealed ducts to meet with the cool air inside as directly. Insulation is installed to specifically prevent condensation from forming. If you, for some reason, installed your own duct work and didn't use insulation because you thought it was only for cold weather, this is a problem and likely the reason you have wet vents.

Once you have discovered wet vents, it is important to call your JR Perkins Heating & Cooling HVAC service technician to fix the cause. If the cause is not immediately apparent, your technician can help you find it and fix it. They can ensure your ducts are sealed tightly and find signs of compromised insulation. Furthermore, your service technician can help you test and mitigate mold and mildew within your duct work.
