- Air Conditioners
- Hot Water Heaters
In houses with forced-air heating and cooling systems, ducts are used to distribute conditioned air throughout the house. In a typical house, however, about 20 percent of the air that moves through the duct system is lost due to leaks, holes, and poorly connected ducts. The result is higher utility bills and difficulty keeping the house comfortable, no matter how the thermostat is set.
Your home may have poorly performing ducts if:
- You have high summer and winter utility bills
- Rooms are difficult to heat and cool
- Rooms are stuffy and never seem to feel comfortable
- Ducts are located in an attic, crawlspace, or the garage
- There are 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. Some homeowners choose to take on duct sealing as a do-it-yourself project. Start by sealing air leaks using mastic sealant or metal tape and insulating all the ducts that you can access (such as those in attics, crawlspaces, unfinished basements, and garages). Never use duct tape, as it is not long-lasting. Also, make sure that the connections at vents and registers are well-sealed where they meet the floors, walls, and ceiling. These are common locations to find leaks and disconnected ductwork.
The Aeroseal Duct Sealing Process
How does Aeroseal Work? Aeroseal is a patented breakthrough technology that tackles duct leaks from the inside out. The Aeroseal process puts escaping air under pressure and causes polymer particles to stick first to the edges of a leak, then to each other until the leak is completely sealed.
To start the Aeroseal duct sealing process, all room ceiling or floor registers are replaced with foam plugs. A small access hole is cut into the supply or return air plenum and a temporary collar is attached. The air conditioning indoor coil, fan, and furnace are temporarily blocked with a foam plug to avoid the entrance of any sealing particles into this equipment.
Once the system is properly sealed, the patented injection machine is connected to the air duct system using a flexible plastic tube. The exclusive Aeroseal duct sealing system injects adhesive particles into the air duct system. The particles travel through the air duct system seeking holes and cracks that are located throughout the ductwork. The adhesive duct sealing particles attach directly onto the edges of any hole and crack effectively sealing it without coating the inside of the ductwork.
