Test protocol 04 · Air-duct cleaning

Can a 16-vent quote survive a change order and photo report?

The benchmark covers quantity-based pricing, technician permissions, add-on approval, before-and-after photo pairing, final reports, payment, and long-term evidence retrieval.

Illustrative field context

Canonical scenario

The 16-vent change-order test

  1. A synthetic home with two HVAC systems and 16 vents
  2. Three priced add-ons and one discovered change order
  3. Twelve before-and-after photo pairs
  4. A six-month retrieval test for every customer artifact

Evidence captured

What earns a claim

Quote
Quantity line items, setup time, add-ons, and revision clarity.
Approval
Customer response path, latency, technician permissions, and audit trail.
Photo proof
Pairing, metadata, compression, captions, and final report quality.
Reconciliation
Approved change order versus invoice and accounting export.
