Duct Work and Sealing
Duct work is an essential part of a home's energy performance as it is the distribution system of conditioned, filtered air throughout your house. Most duct systems are located outside your conditioned space, usually in the attic or crawlspace.
During the heating and cooling seasons, your heating and air units are working hard and the duct system is the delivery system that conditions your home. If your ducts are leaking, you are conditioning the outside space your ducts are located — such as the attic or crawlspace. In other words, those are dollars out of your pocket. And because you are conditioning extra space, your unit works even harder with a final result of comfort issues, air quality problems, high bills, or all of the above.
Types of Duct Sealing
Prescriptive Seal
Used when your duct system has low-to-moderate leakage. Our crews perform certain pressure tests to determine the high leakage areas and only hand seal those areas. This is a great low-cost and effective option.
Strip-and-Seal
A complete system seal. The current duct insulation is removed, our crews hand seal every seam and connection by hand, and then the system is re-insulated. This is usually the most expensive option but usually more effective.
AeroSeal
A new technology that seals ducts from the inside. Our AeroSeal-certified crews pressurize the duct system that allows them to inject a sealant. As the sealant tries to escape through all the leakage areas, it closes it and then hardens like cement. This is a great option where ducts are inaccessible or the insulation is still in good condition.
Sometimes duct efficiency work involves new duct work installation. When ducts are rusted and in terrible condition, new duct work is generally the solution versus duct sealing.
