Mold and mildew can grow on your ceilings and walls, as well as in your attic, basement or crawl space if your ductwork is covered with moisture. Your home’s structural integrity and your family’s health could also be put at risk if you have mold and mildew growing in your ducts. This is why it’s very important to learn how to prevent and treat condensation on your ducts. Fortunately, Entergis Testing and Sealing, LLC has provided a helpful guide to sweaty ductwork in this post.
What Causes Duct “Sweat”?
Condensation can be caused by a variety of factors, according to HVAC installation providers. It forms on your ductwork for two main reasons: first, uninsulated or inadequately-insulated ducts; and second, humid air regularly coming into contact with chilly ductwork. Condensation will begin to accumulate on the surface of your air conditioning ducts as the humidity level outside rises. Ductwork sweating is more likely when the air inside the ducts is cooler.
How to Prevent Ductwork Condensation
Ensure that you have proper insulation. Since ducts are mainly composed of metal and lack intrinsic insulating characteristics, they’ll absorb the majority of the heat that passes through them. Insulating them properly helps prevent condensation from forming and guarantees that your ducts will function effectively for years to come.
Keep your ducts properly sealed. This is to maintain safe humidity levels in your home. Cover holes and openings in the wall near your ductwork. The less moisture that travels through your ducts, the less likely condensation will be to form. Remove the register or return grill and plug the duct openings to seal your unit. Large duct openings can be secured by covering them with plastic sheets. Other high-humidity areas, such as the bathroom and kitchen, should also be thoroughly ventilated.
Install a dehumidifier. Dehumidifiers keep your home at an ideal moisture level all-year-long, preventing condensation in plumbing and ductwork that impacts your indoor air quality. For ductwork that runs through attics and crawl spaces, this is an excellent option.
