Duct Sealing

If your home uses a forced-air system such as a central air conditioner or furnace, you’re using ducts to stay comfortable – and you’re probably wasting money. After all, the average system loses 30 percent of conditioned air (and the energy it takes to heat or cool it) to leaks in the duct system. Those leaks not only inflate your energy bills, they also put added wear and tear on your system.

Aeroseal®: available only from Hurley & David

While we provide several options for duct sealing, by far the most accurate and efficient is the Aeroseal system, of which Hurley & David is the exclusive provider in the region. The Aeroseal system uses advanced technology to determine the exact degree of ductwork air loss: we will show you in no uncertain terms exactly how wasteful your installed system is. Aeroseal then injects a polymer particles that attach themselves to the areas of leakage, sealing them from the inside. (This technology was originally developed by research funded by the U.S. Environmental Protection Agency and U.S. Department of Energy.) We will then run the same test to show you the degree of efficiency gained — usually, nearly 100%, meaning the virtual elimination of duct leakage.

More About Duct Leaks

As you might expect, the joints in your duct system are some of the most vulnerable places for leaks to show up, although holes can appear just about anywhere. In addition to energy loss and reduced comfort, duct leakage can lead to the distribution of air that has not gone through the system’s filter into the spaces where you live and breathe. It’s not just a waste of energy; it’s a legitimate health issue where allergies or asthma is concerned.

Leaks for the system to work extra hard to deal with unconditioned air from your attic, basement, or crawlspaces that leaks into the ductwork, leading to maintenance issues down the road. Inefficient ducts sometimes lead homeowners to purchase unnecessarily large systems in an effort to improve comfort, which can be an expensive mistake.

Efficient HVAC performance, depends on balanced airflow; in other words, the amount of air your system takes out should match the amount of air it takes in. Leaks cause an air pressure imbalance, and the resulting low-pressure areas act like a vacuum cleaner, pulling in air from outside or from unconditioned spaces in the home. This leads to drafty or uncomfortable rooms and, again, poor energy performance.

Finding the leaks themselves is important because it helps us determine the right way to solve the problem. The best technique to seal your ducts depends on the type of ductwork and the size and accessibility of the leaks. In addition, we can add insulation around the ducts proper to make sure that conditioned air maintains its temperature as it cycles around your house, eliminating another source of energy loss.
