In a typical ducted home in Gurnee, Illinois, somewhere between 20 and 30 percent of energy is lost due to leakage from ducts. This increases your home’s heating and cooling costs and creates health and comfort issues. Sealing ducts properly can improve energy efficiency, comfort, and indoor air quality in your home.

Energy Efficiency

In a centralized HVAC system, air passes through lengthy ducts before being circulated in your home. If these ducts have holes, gaps, or leakages, a substantial amount of treated air could escape from them. Lack of proper insulation also causes heat loss from ducts. In either case, your system will have to work harder and longer to reach your desired temperature. So sealing ducts saves big on utility bills.

In a study carried out by the Department of Energy, duct sealing was found to be the least expensive of 12 measures studied and also yielded the highest energy savings.

If you are installing a new system, proper duct sealing reduces the size of the system required to heat or cool your home, saving you money. Higher efficiency also means less pollution, which in turn contributes to a cleaner, greener environment.


Lack of sealing is often associated with a number of comfort issues. Some rooms might take longer to cool or warm than rest of your home, while others might feel stuffy and uncomfortable. Sealing ducts offers better dehumidification and keeps the temperature even throughout the home.

Indoor Air Quality

If ducts are not sealed properly, dust, debris, chemicals, and other pollutants can enter the ductwork and turn it into a breeding ground for mold, insects, and pests. This would pollute the air passing through the ducts and circulating through your home, making the indoor air unfit for breathing. Sealing ducts minimizes the risk of indoor air pollution.
