For US HVAC contractorsA made-up unit. Not a real serial.
An AI receptionist for HVAC answers the call, books the job, and handles the change. Carrier gives you 90 days to register it. Trane, Goodman and Daikin give 60. A day late at Carrier and ten-year parts becomes five-year parts with no labor, and in year six that call comes to you. It is one of five jobs in an HVAC shop that nobody owns. Below, an AI does each of them on a made-up shop.

Sheet 01 / 07The 9pm call
It is 9pm and your on-call tech is already out. Somebody has to decide whether this one rolls a truck tonight, and if she gets 8am, whose tune-up moves.
Try itBe the homeowner. No cooling with a baby in the house, a noise that can wait, a gas smell. Wes decides, and the board moves.

A system signed in the kitchen at 11pm is a door-to-door sale with 3 business days to cancel, and the emergency waiver needs handwriting no software can produce. So Wes books the call-out and never closes the sale. 16 CFR 429 · Deeplathe does not give legal advice.
A seeded shop, not a real one. Wes runs on a real AI model, and nothing he sends, books or moves is real.
Trade businesses with fewer than 5 technicians turned 24% of their calls into jobs. Those with 25 or more turned 59%, and HVAC shops of every size 38%.

One truck stays in one town, so the sheet runs town by town (Chandler 14, Gilbert 13, Tempe 13), and inside a town the longest overdue with the oldest unit comes first. 5 members are on the shop’s do-not-call list and left off.

Sheet 06 / 07The rails
You run the shop now, and this is Wes on your side of the desk. Some of these he does. Three he will not, and the no is code that runs before any AI model is asked, so asking twice changes nothing. It is the reason you can put your own login behind him.
WesThis is Wes, the AI dispatcher on this page. Ask me what I would do in your shop, or ask about anything on Sample Street's board. It is a made-up shop.

Does Fills the registration from the data plate and watches the window.
Never Changes an install date, or says whether something is covered.
The submission is under your login, and coverage is their answer, not ours.

What actually happens
You have been sold to before, so here is the whole of it rather than a promise. Nothing below needs an integration we do not have.
The call
Fifteen minutes. Which brands you carry, which jurisdictions you pull permits in, and how many changeouts you did last month.
You talk, we listen.
Before you pay anything
A working board with your own last month of jobs on it: your brands, your windows counted from your install dates, and no customer names in it.
We build it. You look at it.
If it is wrong
You say so and we stop. There is no invoice and nothing to cancel, because nothing started.
Costs you the fifteen minutes.
If it is right
One monthly fee covers building your version and keeping it running. No setup fee. Stop at the end of any month, and thirty days back from go-live, prorated.
You press submit. It always was you.
The three things we would need from you
Your job list
A CSV, an export, or read access to Jobber, Housecall Pro, Service Fusion or Workiz. ServiceTitan does not permit it, so there it is an export.
Which brands you carry
The window is per brand, and it is the only figure here that is not yours.
Your jurisdictions
Permit portals are per city and per county, and each one is its own form.
And nothing from a manufacturer or a city, which is the point. They give nobody a way to connect, and that is the reason this work is still sitting on somebody’s desk.
The honest part
Nobody has bought this yet. You would be the first, and you would see it working on your own jobs before paying for it.
4 manufacturer windows are built and sourced: Carrier, Trane, Goodman, Daikin. Lennox, Rheem, York/JCI, Mitsubishi publish no window we could find, and the board says so rather than guessing one. The rest is your job list and your jurisdictions.
Take the fifteen minutesSheet 07 / 07What it costs
Move the sliders to your shop. Every figure comes off the published price list, and where the honest answer is custom it says so instead of guessing.
