Certified technicians draw on more than 20 years of experience as they scour ducts with airbrushes and HEPA-filtered, negative-airflow machines. This process removes large accumulations of dust, debris, and allergens that have built up over the course of years. In addition to purging air pipes, the techs' services include free inspections, vent cleaning, and mold and mildew removal. They can also sanitize entire systems to expel the lingering traces of germs and four-letter words.
