We guarantee that when we finish cleaning your air duct system there will be no visible dirt in the system and you will be able to turn on your air conditioner or furnace, without having dirt or debris blow out.  To make this guaranty, we must clean every square inch of the duct system from beginnng to end, which includes the air conditioner and furnace.  In Texas, a contractor must have state Air Conditioning and Refrigeration Contractors license in order to clean air duct systems, to international standards established by the Natonal Air Duct Cleaners Association (NADCA).
