Air Duct Cleaning Before & After Photos

These real Zarts images show accessible sections of flexible duct, sheet-metal duct, room-side openings, and lined HVAC components before and after dust and loose debris were removed. The existing duct material was cleaned—not replaced or refinished.

Real Zarts service photos. Captions describe visible conditions. The photos do not establish a customer, city, property, date, measurement, health result, or whole-system outcome unless expressly stated. Select a photo to view it full size.
Field image 1Flexible duct inner liner: visible dust on the photographed section is substantially reduced in the After view. Cleaning removes accessible deposits; it does not replace the liner.
Field image 2Rectangular sheet-metal duct: the accessible side and upper surfaces show less visible dust in the After view. Existing marks and color variation remain because cleaning does not refinish the metal.
Field image 3Room-side metal duct opening: visible dust on the accessible surrounding metal and rear panel is reduced in the After view. The photograph does not identify the opening as supply or return air.
Field image 4Flexible duct inner liner: visible dust around the accessible interior is substantially reduced in the After view. The existing liner retains its original color and condition.
Field image 5Fibrous-lined rectangular duct: fewer loose particles are visible on the lower surface in the After view. Camera distance and lighting differ, and the lining itself was not replaced.
Field image 6Fibrous-lined rectangular duct: loose fragments visible on the lower surface in the Before view are largely absent in the After view. Existing spotting and color variation in the liner remain; cleaning does not renew or replace this material.
Field image 7Flexible branches at metal takeoff collars: visible dust on the accessible openings and surrounding plenum surface is substantially reduced in the After view.
Field image 8Fibrous-lined duct: loose particles across the lower surface are reduced in the After view. The lining retains its existing discoloration because cleaning removes debris rather than replacing the duct material.
Field image 9Lined duct corner: the After view shows less visible dust and loose material on the accessible surfaces. Existing color variation remains, and the different orientation limits a direct comparison.
Field image 10Lined plenum and two round branch takeoffs: visible dust on the accessible surfaces is substantially reduced in the After view. The underlying liner remains the original material.
Field image 11Lined HVAC interior: visible dust on the photographed surface is reduced in the After view. The public image does not establish the exact component, and cleaning does not restore the liner to a new appearance.
Field image 12Lined HVAC interior around a large round metal connection: visible dust on the accessible area is reduced in the After view. The photograph does not identify the exact cabinet or plenum section.
Field image 13Room-side metal duct opening: visible dust and loose debris on the opening and accessible interior are substantially reduced in the After view. The comparison documents only this opening.
Field image 14Rectangular duct section: visible dust on the photographed surfaces is substantially reduced in the After view. Camera orientation and distance differ, so the comparison is limited to those accessible surfaces.
Field image 15Rectangular duct section: visible dust on the accessible surfaces is substantially reduced in the After view. Lighting and camera orientation differ, and the image does not document the full branch.
Field image 16Fibrous-lined rectangular duct: loose white fragments across the lower surface are greatly reduced in the After view. The original lining, including its existing color and wear, remains in place.
Field image 17Bathroom exhaust fan: visible dust on the exposed blower wheel and housing is substantially reduced in the After view. The photograph does not document airflow or operation.
Field image 18Flexible duct inner liner: visible dust around the accessible interior is substantially reduced in the completed After view. The existing liner was cleaned rather than replaced; a separate in-process image is not used as the final result.
Photo context and evidence standards

Before-and-after photographs can document a visible change in a specific, accessible section of an HVAC system. They do not show every branch, prove a health outcome, or establish how the entire system performed. The captions therefore describe the component shown and the removable material that is visibly reduced.

These images come from real Zarts service work. Where complete job details are not available for publication, we do not assign a customer, city, property type, airflow measurement, or equipment setting to the image. The purpose of this gallery is to show realistic cleaning results without turning a close-up photograph into a whole-system claim.

Cleaning removes dust and loose debris—not the duct material: Air duct cleaning removes accessible dust, loose debris, and other removable buildup within the agreed service scope. It does not recolor, refinish, or replace flexible-duct liners, fiberglass duct board, insulation, or sheet metal. Existing stains, age-related color variation, wear, and permanent discoloration may remain after the loose material has been removed. An After photo should be evaluated by the reduction of removable material—not by whether the original duct looks brand-new. Making old or damaged material look new may require repair or replacement, which is a different service.

How to read a duct-cleaning comparison

Start by identifying the material and component. Flexible duct has an inner liner that requires different handling than bare sheet metal, while fiberglass duct board and internally lined sections require material-appropriate methods. A clean register cover also should not be confused with a cleaned branch duct, plenum, or return-air pathway.

Lighting, camera angle, and distance can change how a surface appears. The strongest comparison uses a similar view of the same accessible area and focuses on removable dust and loose debris rather than the color of the underlying material. Recommendations for a specific home should be based on inspection, system layout, material condition, and access—not a generic gallery image.
