HVAC
No ReKeying — Every Field Change Order Captured and Approved Digitally
A tech discovers extra scope on-site — a corroded pipe, an unplanned material upgrade, an additional hour of labor. He calls it in verbally. The customer nods. The invoice comes out two weeks later with line items nobody recognizes. No ReKeying means scope changes captured in the field flow directly to the invoice with a digital approval trail.

How Change Order Management Actually Looks in HVAC
The Scenario
A tech is replacing a condenser coil and discovers the wiring to the disconnect is deteriorated and needs replacement. He calls the office, the service manager verbally approves the extra $320 in materials. The customer gets an invoice two weeks later with a line item they don't recognize.
The Real Impact
Verbal change order approvals on HVAC repairs result in invoice disputes on 15–25% of multi-line service jobs, with average disputed amounts of $400–$1,800.
Does This Sound Like Your HVAC Operation?
- !Customers dispute invoice line items they don't recall approving
- !Verbal scope approvals don't hold up when the customer pushes back
- !Techs add scope without realizing it needs a separate authorization
The Cost of Doing Nothing
Undocumented change orders are the #1 source of invoice disputes. The average disputed amount is $1,200–$4,000 per incident. At 5 disputes per month, that is $72K–$240K/year in contested revenue.
