The truth about DIY duct cleaning
Shop-vac and a coat hanger vs. professional truck-mounted equipment. Spoiler: it's not close.
You can absolutely improve your indoor air yourself. What you can't do with household tools is clean a duct system.
What DIY does well
Vacuuming registers, wiping grilles, replacing filters, and clearing the area around the air handler. All worthwhile, all safe.
Where it breaks down
A shop vac has a fraction of the airflow needed to capture dislodged debris, so most of it travels deeper into the system or into the room.
Household vacuums don't have HEPA filtration, which means fine particulate goes straight back into the air you breathe.
Rigid rods and brushes can puncture flex duct or crush insulation, creating leaks that cost more than the cleaning would have.
What professional equipment adds
Negative-pressure containment on the system, agitation tools sized for each duct type, HEPA collection, and camera verification so you can see the result rather than trust it.
