Do you know that the duct is a crucial component of your heating and cooling system? Unfortunately, it is most often overlooked during home improvement and maintenance service. With this, they become prone to leaks and connection gaps that allow air to escape. Do you have these issues in your duct system? See how duct sealing and maintenance helps!

How Does Duct Sealing and Maintenance Works?

Duct maintenance includes cleaning and checking the entire duct system. When it identifies the presence of leaks, you need to provide an immediate sealing solution. Duct leaks take place due to improper installation or years of normal use of the ducts. According to the US Department of Energy, duct leaks can cause up to 30% loss in the total output of your comfort systems.

Painting mastic into the leaks is the most common duct sealing solution in residential homes. Mastic is a stiff but flexible epoxy that can seal the hole while moving without cracking. For complex leaks, mastic needs to be supplemented with metallic regulation tape to seal the holes fully. Duct sealing is recommended at least twice a year to cope with the new-formed leaks.

Benefits of Duct Sealing

A well-designed and properly sealed duct offers a lot of benefits:

Comfort. Duct sealing fixes hot and cold spots in rooms. It provides even, comfortable temperature in the house.

Indoor Air Quality. The leaks in the ducts can serve as a passageway for fumes, chemicals, and dust to enter your space, compromising your indoor air quality. No matter how vigilant you are in replacing the filters, still, you won’t get a healthy IAQ with leaks in your ductworks.


Combustion gases are released by gas appliances during their normal operation, and these should be vented out properly. With leaks, however, “backdrafting” occurs which allow these gases to enter and circulate in your home. Sealing the leaks will minimize this risk.

 Save Money

The efficiency of your unit can reduce by up to 30% with leaky ducts. Sealing them will boost your unit’s efficiency and save money on your heating and cooling costs.
