Some homeowners have saved up to 40% of their energy bills after having the Aeroseal air duct sealing system their central air duct system. A typical homeowner should expect to see measurable reduction in energy use for Heating and Cooling.In houses with forced-air heating and cooling systems, ducts are used to distribute conditioned air throughout the house. The result is higher utility bills and difficulty keeping the house comfortable, no matter how the thermostat is set. Duct leakage is a significant problem in many residential buildings that can contribute to energy waste, reduced comfort, poor indoor environmental quality, and moisture problems. Duct sealing alone can save up to 20% of home heating and cooling energy expenditure; therefore, it is important for enhancing building performance. Unfortunately, ducts can be difficult to access (for example, when located in floors, in cramped crawlspaces, or under low, sloped roofs), making the repairs expensive or impossible with traditional manual methods.
How do you know that your home has poorly performing ducts?
You have high summer and winter utility bills.
You have rooms that are difficult to heat and cool.
You have stuffy rooms that never seem to feel comfortable.
Your ducts are located in an attic, crawlspace, or the garage.
You find tangled or kinked flexible ducts in your system.
Benefits of Duct Sealing
A duct system that is well-designed and properly sealed can make your home more comfortable, energy efficient, and safer.
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.
Indoor Air Quality
Fumes from household and garden chemicals, insulation particles, and dust can enter your duct system, aggravating asthma and allergy problems. Sealing ducts can help improve indoor air quality by reducing the risk of pollutants entering ducts and circulating through your home.
During normal operation, gas appliances such as water heaters, clothes dryers, and furnaces release combustion gases (like carbon monoxide) through their ventilation systems. Leaky ductwork in your heating and cooling system 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.
Leaky ducts can reduce heating and cooling system efficiency by as much as 20 percent. 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.
Protect the Environment
Energy used in our homes often comes from the burning of fossil fuels at power plants, which contributes to smog, acid rain, and climate change. Simply put, the less energy we use in our homes, the less air pollution we generate. 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 pollution generated.
