It’s something most Baltimore area homeowners just don’t think to check, but leaky ducts can reduce heating and cooling system efficiency by as much as 20%. Think about 20% of your heating and cooling bills. Sealing and insulating ducts 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, a well-designed and sealed duct system may allow you to downsize to a smaller, less costly heating and cooling system that will provide better dehumidification, making your home feel more comfortable at any setting.

Benefits of Duct Sealing Services

Besides money savings, there are many other benefits to sealing your ductwork. A duct system that is well-designed and properly sealed can make your home more comfortable, energy efficient, and safer:


If you have rooms that are too hot in the summer or too cold in the winter, duct sealing can help. The conditioned air that is going to those rooms may be escaping along the way and never making it there. Sealing and insulating ducts can help eliminate this problem.

Indoor Air Quality

Allergy and asthma sufferers definitely don’t need particles of dust, pet dander, mites, or chemicals floating in the air every time your furnace or air conditioner kicks on. Sealing your ducts can reduce the risk of pollutants entering ducts and circulating through your home.


Gas appliances such as water heaters, clothes dryers, and furnaces release combustion gases (like carbon monoxide) through their ventilation systems. This is normal, but these gases must be vented to the outside for safety. Leaky ductwork may cause “backdrafting,” where these gases are drawn back into the living space, rather than expelled to the outdoors. Sealing leaks can minimize this risk.

Protect the Environment

All homes use energy and this energy often comes from the burning of fossil fuels at power plants. This contributes to environmental issues like acid rain, smog, and climate change. Obviously, the less energy we use in our homes, the less air pollution we create. By sealing your ducts, we increase our energy efficiency, thereby reducing the amount of air pollution generated.
