How to Stop Condensation on Your AC Ducts


Condensation on Your AC Ducts

Condensation is a fairly common issue with ac system ducts. Long-term condensation causes a variety of issues with your air conditioning system. Condensation is commonly seen as water drops accumulating on the outside of air conditioning ducts and vent openings. In severe cases, it can also form small water pools on the flooring and other areas of your home. If not addressed quickly and properly, this poses a health risk and necessitates costly repairs.


What Causes Condensation on AC Ducts?

The main causes of condensation on ac ducts are temperature differences between the air outside and inside the duct, improperly sealed AC ducts, and a lack of insulation around these air ducts.


Ductwork sweating can also be exacerbated by factors such as:

  • Ducts that have become clogged

  • Excessive moisture in the home or attic

  • Air filters that are dirty

Avoiding Duct Condensation

Ductwork Insulation

If you don't already have duct insulation, it's best to get it installed before the summer. Warm air will not be able to reach the cold surfaces of the ducts in this manner. There will be no condensation if these two do not come into contact.


Replace Any Damaged Insulation

If you have insulation but it is cracked or torn, have it repaired or replaced. Warm air can still seep in if the insulating materials do not fit snugly around the ducts.


Maintain The Cleanliness Of Your Air Filters

New or clean HVAC filters can help you save between 5% and 15% on your energy bill. Filters that are dirty can contain pollutants that reduce the quality of the air in your home.


Is it Dangerous to Have Condensation On Your Air Conditioning System?

Small amounts of water on your ducts are not dangerous, but excessive sweating on your vents can raise the humidity levels in your attic. The hot, humid environment promotes the growth of mildew and mold on the drywall and insulation.


Your vents may freeze if water droplets are rolling off your cold ducts and your refrigerant levels are low. Ice-filled ducts are very heavy. If they become too heavy, they may fall through your attic.


As a result, it's a good idea to keep an eye on your duct system and condensate drip pan on a regular basis. If you notice an excessive amount of water on your air ducts and in the drip pan, you should have your system inspected by Beam HVAC today.
