Leaky air ducts can bring unwanted contaminants into your living space, reduce heating and cooling efficiency by up to 20%, and make it harder to heat or cool rooms. Sealing your air ducts can help with all of these problems.
Here are some of the benefits of sealing your air ducts:
Sealing and insulating your ducts helps get conditioned air where it’s designed to go, helping to eliminate hot and colds spots. It also speeds up the pace, getting your home to the desired temperature level a lot faster. This is because air is no longer leaking into other areas of the home, such as attics, basements, and crawlspaces.
Indoor Air Quality
The contaminants that enter your duct system through gaps and openings, including dust, pests, and chemicals, eventually get distributed throughout the home. Sealing air ducts reduces the chance of pollutants getting inside.
When gas appliances like your furnace and water heater are running, combustion gases (carbon monoxide, etc.) are designed to be released outdoors. Sealing your air ducts helps prevent “backdrafting,” which is when combustion gases are drawn back into the building.
According to the U.S. Environmental Protection Agency, “about 20 to 30 percent of the air that moves through the duct system is lost due to leaks, holes, and poorly connected ducts.” These leaks can reduce your HVAC efficiency by as much as 20%. Sealing and insulating your air ducts is an investment that pays for itself in energy savings.
Every time you run a heating or air conditioning system, fossil fuels are burned and greenhouse gases like carbon dioxide (CO2) are released into the atmosphere. Sealed air ducts increase HVAC efficiency and lower your energy use. You can reduce your carbon footprint by sealing and insulating your air ducts.
