Ducts are used to distribute conditioned air throughout a home with forced-air heating and cooling systems. A duct system is the collection of tubes that distribute this air to each of the home's rooms. It can make a big difference in both the cost and the effectiveness of heating and cooling your home. It also has an important effect on the comfort and health of your home's occupants.

About 20 percent of the air that moves through your home's duct system may be lost due to leaks, holes and poorly connected ducts. The likely result is higher utility bills and more difficulty keeping your house comfortable, no matter how the thermostat is set. The performance of your air flow system may be compromised and in need of repair or replacement if: You have high summer and winter energy bills; You have rooms that are difficult to heat and cool; Your ducts are located in an attic, crawlspace, or the garage; Or you find tangled or kinked flexible ducts in your system.
