What a commercial duct cleaning estimate covers
A commercial estimate should cover the air-distribution system being cleaned: supply and return ducts, accessible components, and the evidence of contamination that prompted the call.
It should also name the system count, the areas served, and how occupants or operations will be protected during the work. A building with one rooftop unit is different from a facility with several air handlers.
Building details that change the estimate
- Street address and building use, such as office, retail, restaurant, or light industrial.
- Number of HVAC systems and the areas each one serves.
- Ceiling, roof, or mechanical-room access for equipment and hoses.
- Occupied hours and any quiet periods when work would be less disruptive.
- Visible contamination, recent water events, or prior cleaning and repairs.
- Who can approve the work and any additional items found during the project.
How commercial work is coordinated
- Agree on access windows before the visit, including elevator, loading, or roof access.
- Plan containment and collection so dust and debris stay controlled in occupied spaces.
- Confirm which system components are included and which are excluded.
- Set a written process for approving extra work if the condition is different from the estimate.
- Close service openings properly and leave a record of the areas cleaned.
What is outside a standard cleaning estimate
Ask whether moisture assessment, mold remediation, asbestos handling, pest control or HVAC repairs need a separate specialist. Do not assume a cleaning estimate includes those services, UVC devices or sanitizing treatments.
Cleaning removes accessible debris and contamination from the air-distribution system. It does not repair broken ducts, replace wet insulation, or certify indoor air quality.
