The Air Doctor has a duct cleaning division. Ductwork is often one of the main sources of poor indoor air quality. Every time the HVAC system runs, it pulls air containing dust, pet dander, odors, and other impurities through the HVAC system and ductwork. These contaminate build up over time creating an ideal breeding ground for growths, bacteria, and other microbes. Not only can your home and business’s HVAC system benefit from clean ducts but so can family, customers, and staff members who may suffer from asthma, allergies, and other respiratory ailments.
