Elevated indoor humidity is one of the key contributing factors to sweating ducts or ductwork condensation. Moisture from condensing ducts can be a serious issue if it is not properly addressed in a timely manner. Duct condensation may seem like a minor problem because it can be hard to imagine that a few droplets of water on your ducts can really do that much damage. However, with time, even the most minor moisture sources can lead to serious damage and widespread mold growth.


“Sweaty Ducts” With High Humidity in Cleveland Ohio

Moisture buildup from duct sweat (or condensation) can be a serious problem that can cause various secondary problems in your Cleveland home or business like the following:

  • Water Damage
  • Failing Insulation
  • Structural Issues
  • Mold Growth

Most ductwork is often installed in and routed through inconspicuous areas of the Ohio structure (i.e.: your basement, crawl space, attic, behind building materials, within your ceiling voids, etc.), meaning condensation buildup is often undetectable until secondary problems begin to surface. While difficult to find, once it is found, condensation on your ductwork is often manageable. Contact a trained professional to take a look at your sweating ducts and provide an adequate solution.

What is Condensation?

Condensation presents when water vapors in the hot, humid air comes into contact with the cold surface of your ductwork. The sudden and immediate cooling of the water vapors forces the vapors to convert from a gas state to a liquid state. This leaves behind water droplets or “sweat” on the cooler surface– similar to water droplets on the outside of a cold pint of beer on a hot day.

What Causes Condensation on my Ductwork?

Humidity is common problem plaguing most homeowners. High indoor humidity can be difficult to manage. Elevated humidity means more water vapors in the air around us. The extreme temperature difference between the warm, moisture air around us and the cold surface of your air conditioning ducts make condensation more likely to occur. The warm water vapors fall out of suspension as they come in contact with the surface and leave behind water droplets or “sweat.”

Condensation buildup on your non-porous, metal ducts may seem harmless. However, if the condensation remains unaddressed, it can eventually affect the surrounding porous building materials. Heavy condensation will drip onto or flow to your porous building materials like wood, drywall and insulation and lead to problems like: non-functional insulation, water damage, compromised structural integrity and widespread mold growth.

  • Water DamageAgain, it may be difficult to wrap your brain around the idea that a few drops of condensation can really do that much damage to your home. Well, alone, they can’t. However, lots of droplets of condensation overtime can be a serious problem. When water condenses and drips off of your ductwork onto your porous building materials, it can lead to costly water damage if left unaddressed.
  • Failing Insulation- Water will drip off your condensing ducts and onto your insulation. Moisture buildup in your insulation will diminish its ability to effectively do its job. Water can compress your insulation, which decreases it’s R-value, or ability to insulate. Over time, this can lead to even more problems.
  • Structural IssuesMoisture buildup within porous building materials can compromise the structural integrity of your ceilings, walls and flooring. For example, when condensation collects within your ceiling void or wall voids, the surrounding drywall can rot and collapse over time.
  • Mold GrowthHeavy condensation on ducts (left unaddressed) will eventually drip off your ducts and can feed mold spores. With time, this can lead to a widespread mold contamination. If heavy condensation on your duct work has left you with water damage and mold growth, you may need professional help. A trained mold remediation professional in your Cleveland area can help.
