Booking a duct cleaning for the first time? Here's exactly what a professional job looks like from start to finish — so you know what you're paying for and how to tell a thorough cleaning from a rushed one.
1. Inspection first
A good technician starts by inspecting your system — the vents, returns, furnace, and the state of the ductwork. This confirms what needs doing and gives you a baseline for the before-and-after photos.
2. Sealing and setup
The technician connects a powerful vacuum to your duct system to put it under negative pressure. That way, when the dust is loosened, it's pulled straight out — not blown into your rooms.
3. Agitation and vacuuming
Using brushes and compressed-air tools, the technician loosens dust and debris from the duct walls while the vacuum captures it. Every vent and register is cleaned, one by one.
4. Natural sanitizing
Finally, a natural, non-toxic sanitizer is applied to treat the duct surfaces. Ours is included in the Basic Package and is safe around children and pets.
5. Before-and-after photos
This is the step that separates quality companies from the rest. You should see photos of the inside of your ducts before and after — proof of the work, not just an invoice.
How long does it take?
A typical home takes 2 to 3 hours. Larger homes, two-furnace systems, or ducts that haven't been cleaned in many years can take a bit longer. Your family and pets can stay home throughout.
