Common Air Duct Problems

ENERGY STARÒ is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy to help save money and protect the environment through energy-efficient products and practices. Check their website for an article about common air duct problems. The suggestion to have a return duct in every room that has an air-supply duct is especially pertinent when you are considering buying a new house or updating an existing heating/cooling system.
