      Why Do HVAC Vents Sweat?

      Condensation occurs when humid air comes in contact with the cold air ducts. This is a common problem during summer because of high temperatures.  

      Why Do HVAC Vents Sweat?

      In this post, Superior Air explains the common causes of water spots around your HVAC vents and what you can do to address the problem.

      Causes of Moisture Around HVAC Vents

      • Insufficient Insulation

      If there’s not enough insulation in your attic or duct, moisture is more likely to form in your HVAC vents. This is because the warm and humid air coming from the attic can cause condensation to develop on the cold air ducts and leak. 

      • Air Leak

      An improperly sealed duct boot will enable cold air to escape. You should be aware of this because once the cold air mixes with humid air, moisture will build up around your HVAC vents. Additionally, it’s highly advisable to seal all the seams and connections in your ductwork. This will help you prevent condensation and lower your energy cost.

      Steps to Take

      • Check Ductwork for Moisture, Mold, and Mildew

      When there’s condensation in the air ducts, mold and mildew could form. If you suspect its presence in your HVAC system, consult an expert immediately. Mold and mildew can cause health issues, especially if the spores are being circulated throughout your home by your cooling system. 

      • Seal Gaps and Schedule Maintenance

      Even with your HVAC units, prevention is better than cure. Schedule annual maintenance to ensure that your air ducts and HVAC system are properly sealed. This way, you can optimize your appliance’s performance and reduce energy costs.
