Field Wizard

Field service software for HVAC

Diagnostics that stay in a technician's notebook never get billed

Superheat and subcool readings, refrigerant logs, PM route sheets — the work your technicians already do carefully turns into billable, trackable, defensible records instead of a page of handwriting.

When it goes wrong

How a small gap turns into an expensive one

None of this is one bad day. Each one causes the next.

1

The tech knows what they found. The office knows what got invoiced. Those two things drift apart, and the difference is margin.

2

Refrigerant logs and PM histories are a compliance obligation and a renewal argument, and both are worthless if they're in a filing cabinet.

3

A truck arrives without the part because the parts list on the form was a spreadsheet somebody exported last quarter.

And then

You bill the visit and absorb the diagnosis — on every truck, every day.

The same job, the other way

Where that chain gets broken

The same three steps every trade runs. The difference is that each one leaves a record the next one can use.

1

A technician fills in the HVAC AC No-Cool Diagnostic on the roof — readings, photos, the recommendation — with the parts picker reading live stock, not a stale CSV.

2

It dispatches back to the office with the parts needed already listed, so a return visit is scheduled with the right part on the truck instead of a second diagnostic call.

3

The completed call feeds the invoice — parts used deducted from stock, labor recorded — and the PM history builds per unit automatically.

And then

Nothing gets re-typed, and the record exists before anyone asks for it.
