Who needs this
- An audit or EHS inspection flagged duct hygiene
- Visible dust discharge from supply diffusers
- Persistent odours or stale air complaints from occupants
- Post-fitout or post-construction debris in the system
- No documented cleaning in the last 3–5 years
Standards note. Work follows the NADCA ACR standard for assessment, cleaning and restoration of HVAC systems. Project supervision by a NADCA-certified Air Systems Cleaning Specialist (ASCS #12775637).
How we do it
- 1
Camera inspection
A robot crawler with onboard camera surveys the duct interior and records the baseline condition. You receive the photo log before any cleaning starts.
- 2
Containment and negative pressure
Negative-air machines with HEPA filtration put the duct run under suction so dislodged debris cannot enter occupied space.
- 3
Mechanical agitation
Rotary brushes and air whips — sized to your duct gauge — dislodge settled dust and debris, robot-driven through the run.
- 4
Extraction and HEPA capture
Debris is pulled to the collection unit and captured in HEPA media, not vented to the floor.
- 5
Post-clean verification
The camera pass is repeated on the cleaned run. You receive matched before/after photos and a cleaning log for your audit file.
Proof, not promises
Every robotic hvac duct cleaning project closes with matched before/after photos and a written report. See the documented process and the evidence page for what that file looks like — or check the credentials behind it. Case-specific documentation is shared during scoping.
Robotic HVAC duct cleaning — common questions
How often should commercial ducts be cleaned?
NADCA recommends inspection-driven intervals rather than a fixed calendar: typically an inspection every 1–2 years for offices, with cleaning when the inspection finds measurable contamination. High-occupancy and process environments need shorter cycles.
Does duct cleaning disrupt office operations?
Most work is scheduled after hours or on weekends, zone by zone. Containment and negative pressure mean occupied areas next to the work zone stay usable.
Will you show evidence of what was cleaned?
Yes. Every project closes with matched before/after photos of the same duct sections and a written cleaning log. That documentation is the deliverable, not an extra.
Can robots reach every part of the system?
Robots cover the main horizontal runs; access panels, air whips and manual tools handle branch ducts, risers and terminal units. The inspection report maps what each method will cover before work starts.
