Air Duct Cleaning Service
The EPA says your indoor air is 5x dirtier than outdoors — you get paid to fix that
Air duct cleaning businesses clean the HVAC ductwork in residential homes and commercial buildings using industrial vacuums and brushes. The EPA estimates indoor air can be 2–5x more polluted than outdoor air, and HVAC ducts accumulate years of dust, mold, pet dander, and debris. A single technician with a van and commercial equipment can generate $200K–$500K/year in revenue with margins of 30–40%. Commercial clients — hospitals, schools, property managers — provide repeat annual contracts.

How It Works
Technicians use truck-mounted or portable negative-air machines, rotary brushes, and compressed air whips to dislodge and vacuum debris from supply and return ducts. Residential jobs take 3–5 hours and run $300–$800. Commercial jobs (offices, hospitals, schools) run $1,500–$10,000+. Most operators build recurring commercial accounts that pay every 1–3 years per NADCA standards.
