FOR HVAC, ELECTRICAL, PLUMBING & COMMISSIONING

The reading is the verdict.

Tolerance bands locked on the work order. Instruments post their own readings, checked against the band by arithmetic. Draws release the day the record verifies.

SOUND FAMILIAR?

Hand-logged readings are your word

A number typed into a form is the technician's account of an instrument. Two years later, a warranty claim is argued from memory.

Commissioning reports nobody can check

Forty pages of readings in a PDF, signed at the bottom. The owner can't verify a line; the carrier can't price it.

Retention drags the last 10%

Final payment waits on a walkthrough and someone's confidence. Retention sits for months on work that was in spec the day it was done.

HOW IT WORKS FOR YOU

From work order to released draw

1

Bands on the order

Each criterion names a quantity and its tolerance band — airflow, static pressure, voltage drop — locked before any reading exists.

2

Instruments post

Connected meters and hoods write readings straight to the record. Prompted photos back them up. Nothing records your screen.

3

Arithmetic decides

Inside the band holds. Outside goes to the owner with both numbers. A unit the line didn't name goes to a person, never a conversion.

4

Draw releases

Owner approval, or a verified reading set, releases the draw the same day. The record travels with the payment.

THE DIFFERENCE

A verdict you can recheck with a calculator

Elsewhere a model reads evidence against criteria. Here it doesn't have to: band, reading, and comparison are all on the record.

  • Instrument-posted readings settle on their own; hand-logged ones go to a person with the instrument-face photo
  • Every capture is signed on the device and addressed to the diffuser or circuit it proves
  • A reading outside its band is 'not enough', never a failure of the technician
  • Pick the capture profile per job: instrument-connected, by hand, or full audit trail

PLUGS INTO YOUR STACK

Keep your tools. Add the proof.

Work orders sync in from the field-service system you already run; verified readings and draw status post back.

STRAIGHT ANSWERS

What service and commissioning firms ask first

Our meters don't connect to anything.

Use the by-hand profile: enter the reading and photograph the instrument face beside it. Hand-entered numbers go to a person to settle; the photo makes them checkable.

What about mixed units?

No conversion, anywhere. A kPa criterion and a psi gauge are sent to a person — never to a formula that looks like a pass when it's wrong.

Does this replace the commissioning agent or inspector?

No. Licensed sign-offs stay the authority. Northn puts the readings on a record they can verify line by line, and their approval can trigger release.

Is this another lead site?

No leads, no directory, no cut of your revenue. You bring the contract; Northn runs the money and the proof underneath it.

Technicians build a verified record of readings that were in spec when they took them — their defense in a warranty fight, not a camera on the van.

FOR CARRIERS AND WARRANTY PROGRAMS

A receipt an underwriter can hold

Each month the record freezes one claim per firm — engagements run, policies locked, which adherence conditions held — and anchors it publicly.

Counts and condition names only. No client, no filename, no amount. It sits in an underwriting file without a redaction pass.
