Air Duct Sealing

Air Duct Sealing in Atwater, CA

— Indoor Air Quality Solutions You Can Trust

An air duct leak creates an extremely vulnerable spot in your home or commercial HVAC system. It can make your space extremely uncomfortable and keep your AC from running efficiently. Improperly sealed air ducts can also strain your air conditioning system and accelerate wear and tear, leading to costly repairs and replacements.


You could be losing up to 30% of heated or cooled air in your system through holes, cracks, loose connections in ductwork, poorly designed ducts, and inadequate insulation. Fortunately, Universal Air HVAC provides air duct sealing to minimize air loss and ensure your HVAC system is reliable and efficient.

Why Professional Duct Sealing Is Important

When it’s time for air duct sealing, a professional touch is extremely important. An expert in duct sealing will use the proper materials and techniques to ensure your ductwork is adequately sealed. We use latest tools to test for air loss and find exactly where leaks are. We can address any type of leakage to restore energy efficiency and performance. With professional sealing, we aim for the lowest air loss rate that can be achieved with your system, providing you with short-term and long-term savings.

Signs That You Require Duct Sealing

In the vast majority of homes, ductwork is installed behind walls, in the ceiling, and under the floor. However, there still ways to detect leaks in your duct system, including the following signs:

  • Decreased Heating or Cooling Performance: If one room or area isn’t getting enough hot or cold air, the ductwork serving that location may have a large hole or leak, or it may have collapsed.
  • Higher Utility Bills: An increase in home energy usage and a higher monthly utility bill can mean your heating and cooling system is working harder to compensate for a significant loss of air.
  • Loud Noises: Leaky ducts tend to make noise such as whistling, flapping, rattling, hissing, and rumbling. If you hear any of these sounds, contact Universal Air HVAC for a ductwork inspection.
