Hey Neighbors!
With summer’s heat and humidity in full swing, we’ve been running into a lot of homes dealing with a sneaky problem: Sweating Ducts. If you’re wondering what that means or why that happens, don’t worry – it’s a pretty common issue but definitely something to keep an eye on and be aware of.
What Are Sweating Ducts?
Sweating ducts occur when warm, humid air meets the cold surface of your ductwork, causing condensation – which is similar to when you have a cold glass of iced tea on a hot day. This moisture can collect and drip — as it would on your tea glass — and run down your ducts to cause damage to other aspects of your home.
Why Should I Care About Sweating Ducts?
The moisture running off of your ducts can potentially lead to drywall damage, peeling paint and even mold growth. These issues can potentially build up and lead to costly repairs.
How Can I Tell if My Ducts Are Sweating?
Some of the most common signs your ducts are sweating is if you see damp spots near your vents, water droplets on the ducts, increased indoor humidity or a constant musty smell. These are usually early signs prior to major damage occurring.
What Causes Sweating Ducts?
High indoor humidity and poor insulation / sealing of your ductwork is typically the reason for sweating ducts. This allows warm summer air and humidity to meet the cold surfaces of your ducts.
What Can I Do to Prevent or Fix Sweating Ducts?
The most important action you can take to prevent sweating ducts is to control your home’s humidity by either utilizing a dehumidifier or ensuring your home’s HVAC system is regularly maintained. Properly sealed ducts can also stop any condensation before it starts and causes larger problems.
