The air ducts in your home provide a very important function. Think of them as the lungs of your home. They circulate the air from your heating and cooling system into and out of each room, which allows for consistent interior comfort regardless of the season. Air Duct Cleaning refers to the removal of dust and contaminants within the ductwork. This includes the supply and return air ducts as well as the registers and diffusers in each room. Powerful vacuums whisk away all dust and debris, preventing it from re-circulating throughout the home.
