Professional Assessment Before Cleaning80%
The industry consensus, supported by bodies like the EPA, is that air duct cleaning is not a routine maintenance task for every building. A professional inspection to identify specific problems—such as visible mold, pest infestation, or significant contaminant buildup—is the most recommended first step before committing to the service.

What the Pros Say
"In residential, you're mostly dealing with dust, pet dander, and maybe some light mold. For commercial, the scale is massive. We use robotic cameras, industrial-grade negative air machines, and have to work around complex fire dampers and VAV boxes you just don't see in a house."

Mike Johnson
HVAC Technician, 15 years"For us, it's not optional. It's about compliance, liability, and employee health. We schedule our duct cleaning annually, after hours, to minimize disruption. It's a significant budget item, but the cost of non-compliance or a sick building is far higher."

Sarah Chen
Commercial Property Manager"The biggest difference is the standard of care. A residential job might take a few hours. A commercial project like a hospital or factory can take weeks and requires strict adherence to NADCA ACR standards to ensure containment and prevent cross-contamination. You can't just 'wing it'."
C
Carlos Rodriguez
NADCA Certified Master Technician"Homeowners call us when they see dust or have allergies. Business owners call us because their insurance requires it or they need to meet an industry standard like TR19 for kitchen grease extract systems. The motivation is entirely different, which dictates the process and documentation we provide."
