Home Health: Don’t Let Condensation in Ductwork Make You Sick

Condensation In Ductwork

When it comes to a long life for your HVAC system, condensation in ductwork can be a big concern. Being proactive is an important way to keep problems from raising with condensation.

Here are several things you need to know regarding condensation in your ductwork and how it may affect your home.

What Is Condensation In Ductwork?

Condensation forms when the water vapor in the air drops out of suspension and condenses into a liquid form. The colder the air, the more likely it is that water will condense. Condensation forms when warm, humid air comes into contact with a colder surface like your air conditioner’s ductwork. This colder surface then chills the surrounding air to a temperature below it’s dew point which causes the water vapor to condense into a liquid, just like on the outside of a glass filled with a cold beverage on a hot day.
When the ducts in your home are filled with cool air and the air on the outside is warm, water droplets will form and create damage if not prevented. The droplets that form can cause mold and mildew. Also, it can cause stains on walls or ceilings that may bleed through and cause more damage. The condensation that forms within these ducts can also cause structural damage if not properly repaired.

So How Exactly Is Condensation In Ductwork Prevented?

Insulation – Proper insulation levels can actually prevent condensation form occurring in your ductwork. Proper insulation will ensure that the regulated temperature will be maintained as the air makes its way to your living areas. The ductwork in unconditioned areas, such as attics, floors and ceilings is where ductwork insulation is imperative.
The ductwork in your home should be constructed with special insulation that helps in cutting down and getting rid of the formation of harmful water droplets.
Over time, insulation can become aged or damaged. This leaves gaps that allow water condensation to form within your home’s ductwork. This situation is correctable by adding additional insulation in these problem areas. However, DO NOT USE DUCT TAPE to try and fix these damages.

Keep Your Home Dry and Cool – In order to prevent condensation in your ducts, it is important to keep your home cool and dry during hot and humid weather. To do this, make sure your air conditioner is properly dehumidifying your home.
