The Residential vs Commercial Decision Defines Your Entire Business
Residential duct cleaning (homes, apartments) and commercial duct cleaning (restaurants, office buildings, hospitals, factories) are fundamentally different businesses. They require different equipment, different marketing, different pricing, and produce different margins. This guide compares every dimension so you can make an informed choice.
Residential: Portable HEPA vacuum unit, air compressor with whip system, agitation devices (manual brushes, air snakes), basic inspection camera. Entry-level equipment package: $3,000-$8,000. Professional package: $12,000-$18,000. Most residential work uses negative air with manual agitation — robotic equipment is rarely cost-justified for single-family homes.
Commercial kitchen exhaust: CR360 robotic cleaning system with 360-degree brush, 1080P camera, pressure washer capability. HEPA vacuum (K8). Chemical sprayer (D2 or D7-5). This equipment package ($8,000-$15,000 factory-direct from Gaolijie) enables 2-person crew to clean commercial kitchen exhaust systems in 2-4 hours versus 4-6 hours with manual methods.
Commercial HVAC/industrial: K7S or E200 robotic system depending on duct size. HEPA H13 dust collection. Full video documentation system. Package: $6,500-$18,000 factory-direct.

Which Market Should You Choose?
Start with residential if: You have limited capital (under $15,000), want faster cash flow, and have strong local marketing skills. Residential has lower barriers to entry but also lower margins and more competition.
Start with commercial if: You have industry experience, can invest $20,000-$40,000, and are comfortable with longer sales cycles. Commercial offers higher margins, higher customer lifetime value, and less price competition.
Run both if: You have the equipment for both markets (K7S handles residential HVAC and light commercial; CR360 handles commercial kitchen exhaust) and can manage two different marketing and sales approaches. Many successful Gaolijie customers operate residential and commercial divisions under the same brand, cross-selling between them.
