Why Before/After Photo Proof Matters in AC Duct Cleaning

Once vent covers go back on, you can't see inside the duct. A photo report gives you evidence of what was there and what was removed.

• A before photo and an after photo of the same duct section, from the same angle
• Photos for each thermostat zone, not just one room
• Vents and diffusers as well as duct interiors
• The date of the visit

• They show only the sections photographed, not every metre of duct.
• They don't measure air quality, allergens or microbes.
• Lighting and camera angle affect how dirty or clean something looks.

Use photos as evidence of the work done, not as a health test.

Check that each pair matches the same spot, look for the texture of settled dust in the before shot, and ask the technician about any area that still looks dirty. For a gallery of real job photos, see our Before & After page.
