This visual field note describes the photographed component or setup. It is not a complete customer case study.
What you can see
- The Before view shows visible buildup along the flexible inner liner.
- The After view shows less surface buildup and a clearer view of the liner.
- This is a before-and-after comparison from the Zarts service gallery.
Why flexible duct needs careful handling
Flexible duct has a thin inner liner supported by a wire helix, with insulation and an outer jacket around it. The existing condition of that liner helps determine which tools and access points are appropriate.
Before cleaning, the scope should account for brittle, torn, collapsed, or disconnected sections. Those conditions may call for repair. Zarts pairs controlled compressed-air agitation with negative-pressure collection for accessible duct cleaning; the method is matched to the material and condition found.
What to discuss for your home
Share any visible buildup or recent remodeling, along with your home size and number of HVAC systems. Ask which registers, returns, and duct sections are included, how the work area will be protected, and how completed work will be reviewed with you.
Photo context and limits
- The customer, location, property type, service date, and job identifier are not documented with this image.
- The photo does not show the complete system or establish which components outside the frame were cleaned.
- Airflow readings, tool settings, cleaning duration, and customer outcomes are not recorded here.
A surface photo does not establish health effects, energy savings, or whole-system performance. Read about our field notes and case study standards.
