Starducts, Seattle

From time to time, the technicians of StarDucts Air Duct Cleaning recover cultural artifacts from inside their customers' walls. They have found soda bottles, toys, and paper in vents, along with the standard debris that blocks the passages through which clean air should travel. These treasures aren't exactly typical, but they bespeak a larger need for at-home duct maintenance. In the interest of efficient furnaces and an untainted indoor atmosphere, the StarDucts team wields an arsenal of advanced tools to expel dust, pollutants, and allergens in addition to the odd can of pop.

Negative-pressure vacuums strip away these grimy remnants during cleaning visits, and purge dryer vents of lint that can hinder the machine's function. Furnace inspections pinpoint potential maladies, and electrostatic filters enhance air quality even further by collecting particles with magnetic charges. The staff also installs germicidal UV lights, whose beams shut down bacteria and viruses from inside the duct system. The locally owned business only dispatches seasoned employees on house calls, each of whom must undergo hands-on training while living in vents to learn the culture and language of dust bunnies.
