A well designed and properly sealed duct system can make your home more comfortable, more energy efficient, and safer. Duct improvements can be an excellent investment in your home.


Leaky ducts can reduce heating and cooling system efficiency by as much as 20%. Duct sealing and insulating increases efficiency, lowers your energy bills, and can often pay for itself in energy savings. Plus, if you’re planning to install new heating and cooling equipment, know that a well-designed and sealed duct system may allow you to downsize to a smaller, less costly heating and cooling system.

During normal operation, gas appliances such as water heaters, clothes dryers, and furnaces release combustion gasses like carbon monoxide through their ventilation systems. Leaking ductwork may cause “backdrafting” where these gasses are drawn into the living space, rather than expelled to the outdoors. Sealing leaks can minimize this risk.

Sealing ducts will improve indoor air quality. Leaky ductwork not only leaks air out - untreated and unclean air, dust, insulation particles and other contaminants from crawlspaces and the attic can actually be pulled in to the duct system and circulated into your home aggravating existing asthma and allergy problems.

Energy generation is one of the largest contributors to greenhouse gasses. By sealing your ducts and reducing the amount of energy necessary to comfortably heat or cool your home, you can reduce your carbon footprint.

Sealing and insulating ducts can help with common comfort problems, such as a rooms that are too hot in the summer or too cold in the winter.
