Before approving an unexpected $1,500+ mechanical repair or replacing a condemned unit, have an active trade service manager independently audit the contractor's diagnostic logs, manufacturer warranty records, and repair scope.
Why third-party diagnostic verification is necessary
Every submitted invoice and diagnostic ticket is examined against four trade benchmarks.
Verification of recorded electrical measurements or visual evidence required to condemn high-value parts.
Manufacturer database decoding (Carrier, Trane, Lennox, York, Weil-McLain) by serial number to confirm active warranty coverage before parts are purchased.
Cross-examination of low-cost components ($20–$100 capacitors, pressure switches, expansion tanks) that commonly mimic catastrophic equipment failures.
Turnkey labor benchmark and copy-paste pushback script, backed by 48 hours of written contractor rebuttal review to ensure you are never left without answers.
Enter the diagnosis provided by your mechanical contractor to assess industry misdiagnosis frequency.
Clear, flat fees for documented technical evaluations. No retainers or hidden costs.
For active service calls, claimed component failures, or unexpected repair invoices.
If the contractor pushes back with technical jargon or excuses, forward their reply via SMS/Email within 48 hours. We analyze their rebuttal and craft your written counter-response at no extra cost.

Subject: Trane XR14 Compressor Diagnostic Sanity Check
Status: High Overpay Risk
"I have submitted the diagnostic paperwork to an independent trade advisor for third-party review. Verification of our Trane serial number confirms the unit is under active factory parts warranty through June 2027, covering the compressor at zero equipment cost. Please provide the recorded C-R-S resistance Ohm readings and verify the run capacitor under load before we discuss authorizing compressor replacement."
If the contractor pushes back, disputes the warranty, or responds with trade jargon, do not argue or authorize repairs. Forward their response via SMS/Email. We will evaluate their reply and provide your written counter-response at no additional charge within 48 hours.
Our ethical commitments regarding supported and unsupported mechanical systems.
We audit boiler and hydronic heating diagnostics across gas, oil, and electric systems—including safety relief valve discharge, expansion tanks, auto-fill valves, circulators, and zone valve controls.
Because ductless multi-zone systems depend heavily on on-site architectural variables, we do not audit mini-split quote pricing. We offer our $49 Q&A consult to assess equipment capacity, turndown modulation, and brand selection.
