Indoor Air utilizes the “source removal” method of cleaning air ducts. So big deal, what does that mean, in English? Source removal is a term used in the duct cleaning industry which means one removes the dust and dirt from the duct system by employing two basic pieces of equipment. First, a vacuum powerful enough to pull the debris out of the duct system. Second, some sort of agitation system which will actually get the dust off the inside walls of the ductwork. But don’t be fooled here, source removal is a very general term and has been used very loosely by unscrupulous duct cleaners looking to rip you off. Many claim to use the correct methodologies, yet few take the time or use the elbow grease required to do the job as thoroughly as Indoor Air.
