What the Pros Say
"A DIY kit is like using a toothbrush to clean a garage floor. We use truck-mounted vacuums that create negative pressure, so dust and debris are pulled directly out of the house, not just stirred up. There's simply no comparison in power or safety."
M
Mike Johnson
HVAC Technician, 15 years"We often get calls from homeowners who tried a DIY kit and now have more dust in their house than before. They've loosened debris deep in the system that their shop vac can't capture, and it ends up blowing out of every vent."
S
Sarah Chen
Service Manager, Clean Air Solutions"The biggest risk with DIY kits is damaging the ductwork, especially modern flex ducts. A spinning brush on a drill can easily tear the inner lining, creating air leaks that destroy your system's efficiency and integrity. It's a repair that costs far more than a professional cleaning."
C
Carlos Rodriguez
Master Technician & NADCA Member"A proper air duct cleaning is a whole-system process. It includes the blower motor, coils, and the entire duct network. A DIY kit only touches the first few inches of the vents, which is less than 5% of the job. It's not a real solution."
