Do your ducts seem to be raining water? First off, we do want to mention that water isn’t used in any part of the cooling process, and if any part of your air conditioner seems to be “leaking water” this is not the case. But what is happening is that there is excess moisture from humidity–something we’re all too familiar with here in Mooresville and the surrounding areas–and that moisture causes condensation to form.
When it does so on your HVAC air ducts, this is known as duct sweating, or in some cases “raining ducts.”
At this point, you might be thinking, “Phew, so it’s not a problem!”
That’s where you are wrong, unfortunately. Excess moisture–humidity–can cause a host of problems, from property damage to unhealthy mold growth. This is true no matter where your ductwork is located and is especially problematic in basements and crawlspace. But, how and why does this condensation occur, and what can be done about it? Read on!
