Field Super Intelligence for HVAC service

Your whole service company. One app. Zero chaos.

Dispatch, the tech's phone, quotes, maintenance agreements, purchasing, job cost and billing, in one app built for HVAC service. From the first call to the paid invoice, every job runs on the same live data, and AI handles the busywork.

Built by an operator. Made for the field.

FieldSI was built by an operator who built an HVAC service company from the ground up, so it works the way the field actually works. Every screen follows how a real shop dispatches, quotes, closes out, pays and bills.

What it does

Less typing. More turning wrenches. More money on every job.

Every tool a service shop lives in, wired into one set of data. Anything not built yet is tagged Coming

PM proposals for sales

Snap the nameplate. Walk out with the proposal.

Point the phone at the unit. The AI reads the model, the serial and the tonnage off the nameplate.

The proposal builds itself from your equipment library: the tasks, the hours and the price.

Send it from the roof. Get the signature before you are back in the truck.

Tech AI troubleshooting Coming

A master tech in every pocket.

Ask the phone, not the office. The assistant knows the exact unit: model, serial, refrigerant and its service history.

Step by step diagnosis for that unit, in plain words, while the tech is standing in front of it.

Fewer callbacks. Fewer second trips. Newer techs fixing it the first time.

Fan runs, compressor won't start. Calling for cooling.
On this unit, start at the contactor. Check for 24 V across the coil. The last visit noted a pitted contactor.
24 V there. Contactor pulled in.
Next, the compressor run capacitor:
  • Power off, discharge the cap
  • Rated 45/5 µF. Read each side
  • Under 41 µF on Herm: replace it

Dispatch board

The whole day on one board. Drag. Drop. Done.

Drag a job onto a tech and a time. The board flags lunches, time off and overlaps before you drop.

Live status on every lane: en route, on site, paused, wrapping up, with the minutes since it changed.

Breaks and hours at a glance: 7.5 of 8 hours booked, lunch on the line, and a lockout when nobody ate.

True job cost

Know what every hour really costs you.

Actual wages plus the burden: payroll taxes, workers' comp, benefits and overhead, on every approved hour.

Overtime and double time done right. The multiplier hits the wage. Taxes follow the wage paid. Flat burden never gets multiplied.

See the real margin on every job before you bid the next one.

Union ready

Union shop? Built in, not bolted on.

Load the wage schedule once: journeyman, foreman and apprentice scales, PTO, every fringe fund and dues.

Every hour costs at the agreement in force on the day it was worked, with the funds flat per hour, the way the trust counts them.

The monthly remittance report is one click: hours, gross, each fund, dues and the total due, as CSV or a PDF ready to sign.

Maintenance agreements

Set it up once. The PMs make themselves.

Build the contract once: the sites, the units, the visits a year and the price.

PM work orders are created automatically when each visit comes due, straight into the dispatch backlog with their hours.

Billing is your choice: auto bill up front, or bill on demand when the work is done.

Purchasing and truck stock

Buy it, receive it, cost it. One tap.

Create the PO from the work order: the job, the site and the tech fill in for you.

Buy for the job or for truck stock. Every van is a warehouse with its own counts and minimums.

Save and receive in one step, and the cost lands on the job before it ever reaches billing.

Also in the box

Talk, don't type

Techs tap the mic and dictate their notes and the description of work. AI cleans it up into a clear, professional write-up before it reaches the office.

QuickBooks sync

Customers and invoices sync to QuickBooks Online, so nobody types an invoice twice.

See it live

Three seats. One system. Watch the day happen.

The tech on the roof, the dispatcher at the board and the office closing the sale, all on the same live data.

Big buttons. Zero paperwork.

The tech sees only their own day: the job, the address, the unit, the checklist and the budget. Never a sell price.

  • En route, On site, Pause run the clock, so the timesheet writes itself.
  • Checklists and photos on the job, findings straight to the office.
  • 30 min left tells dispatch when the next job can start.

Questions
