In typical houses, about 20% 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. Like a leaky faucet that slowly and steadily wastes water, your HVAC system’s ducts can prove a sure place to lose dollars, waste energy, and sacrifice air quality.Insulating pipes with the insulating material aluminum foil tape can help solve this problem.
