Leaky supply ductwork causes <br /> expensive conditioned air to be lost before it can be delivered to the house, forcing your system to run longer to <br /> keep you comfortable. <br /> Leaky ductwork can seriously degrade indoor air quality by pulling pollutants and irritants directly into your <br /> house. <br /> Leaky return ductwork can also pull moisture into your home, making it feel uncomfortable even when the air <br /> conditioning is running. <br />
