Duct Cleaning Contractor App: Documenting the Work Clients Can't See (2026)

John Dutton

Manifold is a field documentation app for duct cleaning contractors. It captures GPS-tagged, timestamped before and after photos automatically, supports photo-required service checklists for every vent and register, works offline, and exports branded PDF service reports in one tap. It starts at $16/user/month with no seat minimums.

This guide covers the field documentation workflow for duct cleaning contractors — residential service calls, commercial HVAC cleaning, and dryer vent cleaning.

Why documentation matters for duct cleaning

Duct cleaning services are invisible to the client. They can’t see inside the ductwork before or after. Without documentation, the client is taking the invoice on trust. Before and after photos of accessible duct interiors, equipment setup records, and a completed service checklist transforms an invisible service into a documented one. It also reduces disputes and supports upsell conversations — showing a client duct condition before cleaning is more persuasive than describing it.

Service documentation workflow

Before cleaning starts

Photograph accessible duct interiors at representative locations — main trunk, return air plenum, supply registers. Document visible contamination, buildup, or damage. Photograph equipment setup: negative air machine placement, access points, hose routing. GPS-tagged and timestamped automatically in Manifold.

During service

For commercial or larger residential jobs, photograph access point cuts (before and after sealing), brush agitation passes, blowout of individual runs. For dryer vent cleaning, photograph the vent exterior, lint trap area, and accessible duct sections before and after.

Completion checklist

Use a photo-required checklist: each vent or register serviced with before and after photo, access points sealed and photographed, equipment removed, site clean. Every item locked until the photo is attached. The completed checklist is the service record.

Client report

One tap generates a branded PDF with before and after photos and the completed service checklist. Useful for recurring maintenance contracts, building management records, and IAQ compliance documentation.

Frequently asked questions

How do duct cleaning contractors prove the work was done to clients?

Before and after photos of accessible duct interiors, photographed at representative locations with GPS timestamps, provide visual evidence of the service. Combined with a completed photo-required checklist showing each vent serviced, clients have a documented record of exactly what was done — which a PDF report presents professionally.

What should duct cleaning contractors photograph on every service call?

Before cleaning: accessible duct interiors at main trunk, return air plenum, and supply registers showing contamination level. Equipment setup in place. During: access point cuts, agitation passes for larger jobs. After: the same duct locations post-cleaning, access points sealed, site clean. Each step photographed and tied to a checklist item.

Does Manifold work for commercial duct cleaning documentation?

Yes. For commercial jobs covering multiple zones, mechanical rooms, or large ductwork systems, Manifold’s photo-required checklists ensure systematic documentation across every section. The GPS photo timeline organises all photos to the correct job automatically. The Photo+Scan plan includes Orbit Measure 3D scanning, useful for documenting mechanical room layouts.
