The ductwork running throughout your home is an important part of your HVAC system. The ducts transport conditioned air — whether heated or cooled — throughout your entire home. Over time, it’s not uncommon for the ducts to become damaged, which allows the air inside the ducts to leak out. Even if the leaks are small, it can cause a major increase in your energy costs. Fortunately, duct sealing will repair any cracks, holes and damage to the ductwork while reducing air loss. Duct sealing not only keeps your energy costs low, it also provides other benefits for you, your family and your home.


Damaged ductwork is problematic not only for your utility bills, but also for your health and well-being. Leaky ducts can increase the amount of impurities and contaminants in the air, lowering your home’s indoor air quality. When there are holes or cracks in the ductwork, tiny air particles, including fungal spores, dander and dust, can make their way into the ducts, which then distribute the contaminants throughout your home. These particles can cause allergy and asthma symptoms for your family, as well as headaches, nausea and fatigue. Fortunately, duct sealing helps reduce the amount of particles contaminating your home’s air.

Duct sealing

The ductwork is often hidden in walls, attics, basements and other out-of-the-way areas. This can make it difficult to tell whether the ducts are damaged and need sealing. There are certain signs that will alert you when the ductwork is damaged, improperly sealed or not functioning correctly. For example, if there is a sudden increase in your heating and cooling costs, rooms begin to feel uncomfortable, the home doesn’t stay warm or cool or rooms feel stuffy, duct sealing may be required.
