Duct Doctor

What Duct Doctor does

Duct Doctor USA, founded in 1985 by Dr. Gerald Vanderpool, a board-certified allergist, is a Norcross, Georgia-based franchisor of residential and commercial air duct cleaning services. The company's core offering is professional cleaning of HVAC ductwork and dryer vents, delivered through a nationwide franchise network that spans two countries, 11 states, and more than 150 cities.

Service delivery is built around proprietary, patented truck-powered vacuum systems driven by on-board diesel engines, capable of moving up to 8,700 cubic feet per minute of airflow (claimed to be 30–40x more powerful than portable rotary-brush units) and supported by a 200 PSI air compressor system used for source-removal agitation. All Lead Technicians are required to hold NADCA Air Systems Cleaning Specialist certification, and management includes two Board Certified Allergists, a positioning unique within the indoor air quality trade.

The business model is a hybrid of franchisor economics and end-customer service revenue. At the franchisor level, Duct Doctor collects initial franchise fees (minimum $25,000 per territory, scaled by size) plus ongoing monthly royalties, and provides franchisees with a 24/7 call center, training, marketing materials, and operational systems. End-customer pricing is quote-based, typically ranging from $200 to approximately $900 per residential job depending on home size, duct type, and accessibility. The customer base is split between residential homeowners served via direct-to-consumer channels (phone, website zip-code lookup, franchisee marketing) and commercial/institutional clients (office buildings, hospitals, schools, hotels, military installations) served through a dedicated commercial bidding department. Dryer vent cleaning is offered as a complementary recurring service, particularly to property management companies.
