An answering service built for HVAC companies.
Kaico Voice is an AI receptionist that answers your phones 24 hours a day, books service calls straight onto your calendar, and hands real emergencies to a human. We built it in Tulsa, Oklahoma, where we know exactly what a 100-degree July afternoon does to a phone line. It works the same anywhere weather breaks equipment.
That phone number is the AI agent itself. Ask it whatever a customer would ask you.
The calls you lose are the ones you never hear ring.
HVAC demand is weather, and weather doesn't keep office hours. The system that limped through the afternoon dies at 9 pm. The furnace that short cycled all week finally quits on the coldest night of January. Your heaviest call windows are exactly the hours when nobody is sitting near the phone: evenings, weekends, and the middle of a heat wave when every tech you have is already committed.
Even during business hours, your people physically cannot answer. Nobody picks up a phone from the top of an attic ladder, or halfway through a condenser swap, or while brazing a line set. If the owner is the one answering, the owner is the one not billing. The phone rings when you are least able to reach it. That is not a staffing failure, it is just the shape of the trade.
Meanwhile, the homeowner with a dead AC in July isn't leaving a voicemail and waiting patiently. They are working down a list. They call you, hit voicemail, hang up, and dial the next company. Whoever answers first usually gets the job, along with the repair, the replacement quote if the unit is done, and the maintenance relationship that follows. Voicemail does not lose you a phone call. It loses you the customer.
What it actually does.
Six behaviors, no mystery. This is the whole product.
Answers every call, 24/7.
Nights, weekends, holidays, heat waves. Every call gets picked up, whether it comes in at 2 pm on a Tuesday or 2 am on Christmas Eve. No hold music, no voicemail.
Books straight onto your calendar.
It checks real availability and puts the job on the calendar your dispatcher already uses, with the caller's name, address, callback number, and a plain description of the problem.
Texts back callers it could not help.
If someone hangs up early or asks for something the agent could not resolve, they get a text follow-up so the lead does not go cold while you are in an attic.
Screens spam and robocalls.
Robodialers, solicitors, and junk calls get filtered out before they reach you. The calls that make it through are actual customers with actual problems.
Transfers real emergencies to a human.
A gas smell, or no heat with an infant in the house, is not something we let software handle alone. Those calls get transferred to a person on your team immediately.
Sends a transcript of every call.
Every conversation shows up in writing. You can read at 7 am exactly what happened overnight, word for word, and catch anything that needs a human follow-up.
What an after-hours call sounds like.
It is 9:40 on a Tuesday night in July, and a homeowner's AC has quit. She calls your number. Instead of voicemail, the line picks up on the first ring with your company name. The agent asks what is going on, and she explains: the unit is running but blowing warm air, and the house is at 84 degrees and climbing.
The agent collects her name, address, and callback number, then asks the clarifying questions you told it to ask, like whether a breaker has tripped or the thermostat batteries are fresh. It checks your schedule and offers the first real opening: a technician can be out tomorrow between 8 and 10 am. She takes the slot. The appointment lands on your calendar with the full details, and the transcript is waiting for you in the morning.
One important exception: if at any point she mentions a smell of gas, the booking flow stops and the call is transferred to a human immediately. That is the standing rule for anything that sounds like real danger.
The proof, stated honestly.
Our documented case study is not an HVAC company. It is Tri-Tech Auto Tinting, an auto services shop here in Tulsa. We think that makes it more useful, not less, because the mechanics are identical to yours: a call comes in, nobody can answer it, and the job is either captured or lost to the next shop down the list.
In 30 days on Kaico Voice, Tri-Tech had about 7 appointments booked from calls that would otherwise have been missed. At the shop's $280 average ticket, that is roughly $1,960 per month recovered.
The basis matters, so here it is plainly: the bookings were confirmed from system data on June 27, 2026, and the dollar figure uses the shop's average ticket, a number the owner provided, not a projection. The full breakdown is on our proof page.
An HVAC service call is its own math, and we are not going to invent a number for your ticket sizes. You already know what one lost after-hours call costs you, especially when the repair turns into a replacement conversation.
Pricing that fits the math.
Month to month. No contract. Cancel whenever you want.
One flat subscription, no setup fee, no contract. The price in a slow shoulder season is the price in the middle of a July heat wave.
We will not pretend to know your average ticket, but you do. Take what one lost service call actually costs you, including the repair you never did and the replacement quote you never got to give, and weigh it against $250. The service does not need to save many calls in a month for the math to work. And if it is not obviously paying for itself, cancel. That is the whole pricing conversation.
Frequently asked.
Will callers know they are talking to an AI?
It sounds natural, and it never pretends to be a human if someone asks directly. Most callers just want their problem handled: a clear answer, an appointment, a callback. The fastest way to judge it is to call (918) 359-2644 yourself. That number is the agent, answering live.
What happens with real emergencies?
The agent does not handle real emergencies on its own. Calls like a gas smell, a suspected carbon monoxide problem, or no heat in dangerous cold with an infant or an elderly person in the home get transferred to a human immediately. You decide who that human is and how the escalation works.
Does it work with my scheduling software?
The agent books appointments directly onto your business calendar, such as Google Calendar. If your schedule lives inside field service software, tell us on the setup call and we will map out the cleanest handoff for your dispatcher before the agent takes a single live call.
What if it cannot answer a question?
It does not guess, and it does not invent prices. If a caller asks something outside what you have approved, the agent takes a message and texts the caller back so the lead stays warm. You get a transcript of every call, so you can see exactly what was asked and follow up yourself.
How long does setup take?
About a week. We learn your services, service area, hours, and the questions your customers actually ask, then test the agent with you before it ever answers a live call.
Is there a contract?
No. Kaico Voice is $250 per month, month to month. You can cancel any time. There is no long-term contract to sign.
