HIGH UTILITY BILLS?
STUFFY ROOMS? DUSTY HOUSE?
IT COULD BE YOUR DUCTS.
A duct system that is well-designed and properly sealed can
make your home more comfortable, more energy efficient, and

Sealing and insulating ducts can help with common
comfort problems, such as rooms that are too hot in the
summer or too cold in the winter.
Sealing ducts can help improve indoor air quality by
reducing the risks of pollutants entering ducts and
circulating through your home. Fumes from household
and garden chemicals, insulation particles, and dust can
enter your duct system through leaks and can aggravate
existing asthma and allergy problems.
S a f e t y
During normal operation, gas appliances such as water
heaters, clothes dryers, and furnaces release combustion
gases, like carbon monoxide, through their ventilation
systems. Leaking ductwork in your heating and cooling
system may cause “backdrafting,” where these gases
are drawn into the living space, rather than expelled to
the outdoors. Sealing leaks can minimize this risk.
Leaky ducts can reduce heating and cooling system
efficiency by as much as 20 percent. 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.
Protect the Environment
Energy generation is one of the largest contributors to
greenhouse gases. By sealing your ducts and reducing
the amount of energy necessary to comfortably heat or
cool your home, you can reduce the amount of air
