Condensation on Ductwork – What Causes It

If you are one of those homeowners who take condensation in the ductworks so lightly, you probably need to change your viewpoint. This is a serious issue in your air conditioning system that can branch out to secondary problems like mold formation and water drippings in the ceiling.

Read on and find out how this problem takes place and what you should do about it.

What Causes Duct Condensation?

An increase in humidity outside allows for condensation to form on the surface of the ducts. The colder the air that flows inside the ducts, the greater amount of condensation builds up. This activity is the same as taking out a chilled soda from the refrigerator. After a couple of minutes, you will notice sweat forming on the surface of the bottle.

However, condensation in the ducts can be also caused by the following factors which are attributed to the negligence of proper and regular maintenance.

  • Inadequate insulation in the ductwork

Insulation is important especially in the ductworks to prevent the warm, moist air from getting in contact with the cold air ducts. With poor insulation, these factors are able to touch each other and cause condensation to build up. Always check your duct’s insulation and provide a replacement if needed.

  • Excessive moisture in the air

There is a greater risk of condensation buildup if there is excess moisture near the ducts especially in the attic and crawlspaces. And since summer season calls for a very hot outdoor temperature, expect that the condensation level will rise. It is best to have proper ventilation in these areas to remove excess moisture from the air.

  • Blocked air ducts and dirty filters

Blocked air ducts and dirty filters cause the restriction in the airflow. If this happens, the air cannot circulate freely inside the air conditioning system and will turn the temperature cooler. With a higher temperature inside, there is a greater chance for condensation to form. Be sure to schedule regular duct cleaning and replace air filters at least once every three months.

  • Leaking ducts

It is important to find those leaks in the ducts and have them sealed. If the cool air comes out and gets in touch with the warm air outside, condensation will form.

There are several things that you can do to fight condensation buildup. But the best among them is a regular professional maintenance schedule with your trusted HVAC service company.
