AI voice agent · heating & air conditioning
I’ll be straight: this is another “answers your phone” pitch — an AI voice agent, and I know how that reads. I’m not in HVAC. I install one thing and leave.
$2,500 once — payable the day it picks up on your shop’s number.
You own it. No subscription.
90-day full refund. No conditions, no partial credit.
Telephony and AI charge you what they charge, straight to you, under logins that belong to you and never to me. I make nothing on either meter.
Tell it your AC quit and see what it does with you. Dial it as often as you like: this end never rings back, and there is nobody on it to sell you anything.
Seth · CoilCall
Typed out from a real call. Stumbles left in. Two stretches are trimmed where marked above.
Do the same thing yourself.
Same part, my bench. This line answers on accounts and models of mine; yours gets built inside your own accounts, on the models sitting in them, so it can sound and handle a call a little differently.
If you dialed it already
Most people call the number first and read the page after. So this part comes before the sales pitch, not after it.
It booked you
Reasonable. The whole figure is printed twice — once in the first screen, once further down — one amount, one time, plus the usage that runs under your name. Nothing is held back until you agree to a call.
You hung up partway
The visit gets locked in the middle of the call, but the full date — weekday, month, day, year, hour — only comes out at the very end, right before goodbye. Ride it to the end and you’ll hear the whole thing spoken back.
You made up an email
Give it a real address and the confirmation reaches you — that’s the product, not a mock-up. The calendar invite rides along with it, dated and timed the way the agent said it.
Where the call goes
This line books; it doesn’t phone anyone afterward.
Nothing rings back at you afterward, and no salesman is parked behind it. The call is the whole demo.
Get a clean run out of it
Catch it doing something dumb and you’ve handed me a punch-list item — I clear it before yours takes a single call.
One-way traffic: you dial in, nothing dials back out, and there is nothing on the line to buy.
Ask it flat out if it’s a machine, and it says yes.
Nothing dressed up here
No human answers it — that’s the point.
Ask whether there’s a person on this line. It will say no. You’re not paying for a voice good enough to trick a homeowner. You’re paying for a line that answers at 9 on a Sunday night in July, keeps the address straight, and puts a tech in a window before the caller reaches the next shop on the list.
Push on it yourself (737) 312-4002It opens with a real question about the system — not a menu, not a beep.
It reads the callback number back and waits for a yes. A line that quietly invents a phone number is worth less than no line at all.
One article, installed
Your trade is yours. Nobody here is going to tell you how to schedule a route, price a coil, or when to send a tech. There is exactly one thing to hand over — the calls nobody in the shop gets to — and it rides on the number your customers already dial.
It stays on the trucks, the yard signs, the invoices and the fridge magnets. Your number stays yours — never ported, never changed, and nothing about it looks different from the outside.
It offers only the visit windows you set at install — never more jobs per day than you allow. It reads nothing of yours, decides nothing for you, and never squeezes a fifth call into a four-call afternoon.
You download nothing and set up nothing — no box on the wall, no screen for anybody to check between service calls. If a phone can ring, it works.
Nobody here is counting down anything. The figure reads the same next month, the line answers just the same, and you can dial it twenty times before you make up your mind.
The same call, laid flat
Each stamp below is a real timecode from that same test. None of it is a sketch of what might happen one day.
Answers every call, 24/7 — nights, weekends, the middle of a heatwave. No greeting menu, no beep, no “your call is important.”
“This is CoilCall front desk — is your system not cooling, not heating, or is this a maintenance visit?”
It asks what’s wrong, gets the address, and reads it back — street number, street, city, out loud, four seconds after hearing it.
“Got it. 2 2 1 8 East Riverside Drive, and that’s in Austin. Right?”
One question, and the tech knows before he rolls whether the person at the door can approve the work.
It offers real time windows and locks one in during the call. Only the windows you set at install, and never more jobs per day than you allow.
“Perfect. I can get a tech out to you tomorrow at 9 AM or 1 PM. Which works better?”
The number gets read back, out loud, and nothing moves until the caller confirms it. That read-back is left in on purpose: a line that writes down a number nobody confirmed is a line that sends a tech to an empty house.
“Just to confirm, that’s 7 3 7 5 5 5 0 1. I get that right?”
— “Oh, sorry about that. It’s 7 3 7 5 5 5 0 1 3 3.”
“No problem. Let me read that back. 7 3 7, 5 5 5, 0 1 3 3. Is that correct?”
The same read-back loop again, for the email address. Cut for length, marked where it was cut.
Weekday, month, day, year, hour and street — spoken back whole, so the caller can correct it while there is still someone on the line. The appointment date is resolved exactly — right year, right day, your time zone.
“All set. I’ve got you down for tomorrow, Wednesday, July twenty-second, 2026 at 1 PM at 2 2 1 8 East Riverside Drive in Austin. You’ll get a confirmation email in a minute…”
Nobody parked on hold, nobody transferred, nobody told that someone will be in touch. This line books; it doesn’t phone anyone afterward.
Every stamp on this rail is read off the console above — no averages, nothing rounded.
Somebody rambles, somebody calls about a bill, somebody wants a price over the phone. You get a recap of every call, booked or not — so the ones it couldn’t book are still written down and waiting for you, instead of being a voicemail nobody plays back. Anything it misses on my line is mine to work out, and it is worked out before yours takes a call.
What gets written, and to whom
Both leave on their own. Neither one waits for you to type anything.
A structured recap of what happened — the facts the agent captured, written the same way every time. You get a recap of every call, booked or not.
Your customer gets a confirmation email under your shop’s name, with a calendar invite attached.
A calendar invite comes attached to the confirmation email.
The appointment date is resolved exactly — right year, right day, your time zone.
CoilCall’s name appears nowhere on it — it’s your front desk, not ours. What the customer sees is your shop, the address they gave, and the hour they picked.
Your figures, not mine
I have no idea what your book looks like and I won’t invent a statistic to guess at it. The four start low — lower than I’d guess for most shops. Drag them onto yours and the meter moves with you.
Everything that rings, not just the ones you picked up.
Out on a call, up in an attic, or it just rings out.
Set low, and low is where I’d leave it.
A service call and the fix on it. Not a system swap.
On the meter
The four I loaded are set low, and low is where I’d leave them. A figure you can argue with is worth nothing to either of us, so I’d rather sit under than over. Push them up if your shop runs bigger — nothing here will stop you.
The bar under the figure runs to fifty thousand a year and no further. Past that it stops measuring and says so, because a bar pinned to the end tells you nothing.
What the meter shows you is what got away, not what you’ll collect. I can’t promise you the second one and I’m not going to pretend otherwise. Not one number in it is mine either, and you won’t find a borrowed industry statistic anywhere on this site — the ones in circulation have no source anyone can follow back.
Nobody sweating in a living room waits politely. They’re holding a phone with four more shops still on the screen.
The whole cost, in one place
Not a plan, not a tier, not a seat. One install, paid for after it works, and it’s yours outright from that day — the same as the truck.
$0 today.
$2,500 once. The bill comes the day it starts taking calls on the number your customers already dial, and not a day earlier.
You own it. No subscription.
No contract. That’s the last invoice you get from me.
No deadline, no discount.
Because the build is automated — the expensive part was the machine that builds them. So yours gets built first, and you pay once, the day it goes live. So I go first. That’s arithmetic on my end, not generosity on yours — building yours costs me very little.
Two services keep a meter running once the line is up: the phone carrier and the AI. Neither one is mine to resell. They bill you themselves, at list price, on logins you set up on the very first day of the build — I am on that call with you, reading out every field. None of that money detours through me.
Any day inside the first ninety after go-live, tell me you’re done and I send the whole amount back. No conditions, no partial credit.
Fixes are part of the deal. Those ninety days include the help. New service area, a greeting you want reworded, a question it should handle better — I adjust it. No ticket, no invoice.
Say the word and I come take the part off again. Your number keeps ringing the way it rings today, with nothing left on your end to unwind.
The agent, everything written into it, and the setup that puts it onto your line — every piece is yours at go-live. Nothing has to be moved anywhere to get there — it has sat under your name since the build started. It’s under your login, and you can remove my access from it.
Asked with arms folded
Because the others are renting you a phone service and I’m installing a part. The ones I’ve seen bill monthly. Mine is one price, once — and at the end of it the thing is yours, running under your own name, and you can remove my access from it.
None of that has to be taken on faith, either. The line is live and it will book you a visit inside of two minutes.
It offers only the visit windows you set at install — never more jobs per day than you allow. You fix both of those the day it goes in, and nothing in it can push past them.
No. It reads nothing of yours. It offers the windows you handed me, takes the one the caller picks, and emails out the appointment with the invite attached. Whatever you use to run your week keeps running your week.
No. Your number stays yours — never ported, never changed. It keeps ringing on the trucks, the magnets, the old invoices, and the listing your regulars saved fifteen years ago.
Ask it outright whether it’s a machine and it will say yes. No human answers it — that’s the point.
Nothing here pretends otherwise and neither does the line. Trust your own ear over anything written on a website — mine included.
It asks what’s wrong, gets the address, and reads it back — the call printed here has it doing exactly that, and doing the same with the callback number, where it waits for a yes before moving on. That is why I’m comfortable putting it on a real shop’s line.
You get a recap of every call, booked or not. The ones it couldn’t place are written down with the number and what they wanted, waiting where you read your mail rather than in a voicemail box nobody opens.
Nothing up front. One payment the day it starts answering your own number, and from that day the thing is yours outright. The full structure sits one screen up, with the usage costs and the refund window beside it.
There is no second invoice from me, no renewal, and no line item that turns up later.
90-day full refund. Tell me inside the first ninety days after go-live and the money goes back whole. I pull the part back off your line, and your phone goes back to ringing the way it always has.
Seth. CoilCall is mine: I make them, I fit them, and the mail comes to me. I’m not in HVAC. I install one thing and leave.
That console at the head of the page is replaying my own test.
Two minutes, one phone
All of this comes down to one thing: whether the line holds up when you lean on it.
Tell it the house isn’t cooling and follow it all the way to the date. The line takes your call and stops there — no callback, nobody waiting behind it with a pitch.
