Condensation Attic Ductwork

It can also feed mold growth and cause ceiling joists to rot and sheetrock to disintegrate leading to unhealthy air quality in your home and the need for costly structural repairs.

Condensation attic ductwork.

Condensation forms when warm humid air comes into contact with a colder surface like your air conditioner s ductwork. So if you see unusual water staining on any of the ceilings in your home and the roofer has eliminated roof leaks it is likely coming from some fault with the duct system in your home. Let s say your ductwork is in your attic. Ductwork located in an attic must be hung properly so that the insulation can do its job.

Dripping condensation may also lead to a ceiling leak which not only looks bad but also rots drywall and can cause your ceiling to collapse over time. Persistent ductwork sweating may eventually lead to water damage. Condensation on air ducts can be a serious problem. Occasional condensation on a c ducts is not a problem but keeping an eye on the situation is recommended.

When ductwork is touching it forms a very cold spot where they are touching thus condensation begins. The 1 746 square foot house has r 19 insulation between the rafters and between r 15 and r 20 of rigid foam above the roof sheathing. Over time condensation dripping from your ductwork onto attic insulation can cause it to compress which lowers its r value. Excessive condensation can also create conditions favorable to mold or mildew forming in areas surrounding the duct itself.
