But the page "Benefits of A/C Cleansing" on the National Air Duct Cleaners Association (NADCA) site extends this benefit too far by stating: "According to the U.S. Department of Energy, 25 to 40 percent of the energy used for heating and cooling a house is wasted." That's misleading. Although much of the energy utilized to power heating & cooling devices is certainly squandered, that waste is because of inefficient equipment, poor insulation, leakages around windows and doors, and unsealed ductwork.

Running brushes or utilizing compressed air also runs the risk of breaking seals in the duct system, which can be specifically troublesome in the return-air part. Many forced-air systems are developed as closed loops, and leakages in the return-air circuit allow unfiltered air to be sucked from basements or attics, bringing with it dust and wetness.
Versatile coil-style ductsthe kind that appears like a Slinky toyare more susceptible to being punctured. Ductwork produced from fiberglass-insulated materialwhich is less expensive than metal ductworkhas end up being more typical in brand-new homes.
