When dust builds up on the inside of air ducts, it can disperse throughout the home, causing allergic reactions and respiratory issues. With this in mind, the technicians at Perfect Plus Furnace & Duct Cleaning return air ducts to their original state so homeowners can breathe more easily. Air snakes and whips or a motorized rotary brush push dirt and lost Monopoly pieces into the main trunkline, where a HEPA vacuum sucks them away. The staff also mans the phones to answer homeowners' questions about what service is right for them and the likelihood of making a coat out of the lint trapped in dryer vents.
