Duct Sealing

In houses with forced-air heating and cooling systems, ducts are used to distribute conditioned air throughout the house. According to the EPA, in a typical house,however, about 20 to 30 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.
