If you run a plumbing company in Prosper, the phone rings most when nobody can answer it: both hands on a water heater, head under a sink, halfway through a slab leak. The caller gets voicemail, and most people with water on the floor don't leave one. They call the next plumber.
An AI receptionist is a program that answers your business line, or texts back the moment a call goes unanswered, and handles the first part of the conversation the way a good dispatcher would. For a plumber, it explains your services and service area, asks where the water is and whether it's shut off, collects the address, gate code and a photo by text, books the job into the calendar your crew actually uses, flags emergencies to a person, and sends the customer a confirmation.
Who sets one up? We do. Deca Digital is based next door in Celina and builds AI receptionists for plumbing and other home-service companies across North Texas, starting with a free discovery call.
What an AI receptionist does for a plumbing company
The receptionist is a kind of AI assistant trained on your own material: services, service area, the prices you publish, and the questions your best dispatcher asks. Most plumbers start with text-back rather than voice, because someone in a wet kitchen reads a text within seconds and can send a photo.
Its first job is sorting. A slab leak, a water heater leaking from the tank, a burst pipe or sewage backing up is handled differently from a dripping faucet, a slow drain or a running toilet, and you decide which problems count as urgent.
Its second job is asking what a dispatcher would ask:
- Where is the water: which room or fixture, or coming up through the floor or yard?
- Is it still running, and is it shut off? If not, it gives your wording for the shutoff.
- For a water heater: gas or electric, tank or tankless, roughly how old.
- The address, a gate code, and pets or parking.
- A photo by text of the leak and, for a heater, the label.
Prosper has grown from about 30,000 residents at the 2020 census to roughly 44,500 at the Census Bureau's July 2024 estimate, with new homes still going up along Preston Road and the Dallas North Tollway. Every one of those homes has a water heater, and the company that answers first tends to get the call.
A worked example: one missed call during a water heater swap
Say a two-truck plumbing company is replacing a water heater at 10:15 on a Tuesday, both plumbers on the job. A call comes in, and twenty seconds later the caller gets a text.
- Receptionist: Hi, this is the plumbing company's assistant. Sorry we missed you; the crew is on a job. What's going on?
- Caller: Water heater leaking from the bottom, in the garage.
- Receptionist: Pouring or a slow drip? If you can, turn the valve on the cold pipe above the heater clockwise, then text me a photo of the heater and its label.
- Caller: Slow drip, valve's off. [photo] Label says about twelve years.
- Receptionist: Thanks. I can't tell you what it needs; the plumber checks it on site, and anything beyond the service-call fee is priced before work starts. Today 1 to 3 pm, or tomorrow 8 to 10 am?
- Caller: Today.
- Receptionist: Booked, today 1 to 3 pm. What's the address, and is there a gate code or a dog?
- Caller: [address]. Gate code 4471, no dog.
- Receptionist: You're set. Confirmation coming now, and an "on our way" text when the plumber is heading over. If it gets worse, reply URGENT and a person will call you.
The owner's phone buzzes once with the summary: 1 to 3 pm, heater leaking from the tank, about twelve years old, water off, photo and gate code attached. Had the caller written "water is pouring across the kitchen floor," the receptionist would have skipped the booking, sent the shutoff instruction and rung the on-call phone.
The rules you set before it goes live
What it must not do
- Quote a repair. It can state the service-call or diagnostic fee you publish. Beyond that: "the plumber prices it on site."
- Promise a time the schedule can't hold. It offers only the windows you've released. If none fit, it takes a request and says when a person will confirm.
- Diagnose. "Sounds like your pressure relief valve" is a plumber's sentence. The receptionist writes down what the caller said; it doesn't conclude.
It says plainly that it's an assistant, and "Can I talk to someone?" ends the automated part every time.
The handoff to a person
An urgent call rings your cell or the on-call phone while the receptionist stays with the caller, gives the shutoff instruction you wrote, and sends whoever picks up the address and a one-line description. If nobody answers, it tells the caller what happens next and when.
Booking into the calendar your crew actually uses
The booking has to land on the schedule your plumbers look at, usually the one inside your job software. If the software connects directly, the receptionist writes the job in; if not, a booking page or a request-and-confirm step does the same with one tap from you. You set which windows are open, the window length (two-hour arrival windows, not thirty-minute slots) and which jobs need a two-person crew, so a repipe doesn't land in a one-truck gap. What runs after the booking, from confirmations to invoices and review requests, is in our Prosper home-service automation post.
Nights and weekends
After hours the same receptionist runs with different rules: the first morning window, a shorter urgent list, a different on-call number. We've covered what an after-hours assistant should escalate separately.
AI receptionist, answering service or voicemail?
Voicemail costs nothing, but people with an active leak rarely leave one, and those who do leave a name and number with none of the details.
A human answering service puts a real person on the line, which some callers prefer and which handles odd situations better than software. The downsides: the operator reads a script and usually doesn't know your trade or service area, most take a message rather than booking into your calendar, and you pay per call or per minute.
An AI receptionist answers every missed call within seconds, asks your questions in your words and books into your real calendar. Its downsides: it can mishear a name in a noisy garage, some callers want a person immediately, it needs your rules written down first, and it has a setup cost. Our published ranges are $3,000–$5,000 for an assistant with booking and $5,000–$9,000 with phone and job-software integration, fixed quote after the discovery call.
The receptionist is only as good as the rules you give it, so write the rules first.
What to have ready before setup
- Services and service area, including what you don't do (septic, wells, gas lines).
- Your urgent list: which problems ring a person now, and which number.
- The prices you're willing to state: service-call fee, diagnostic fee, and the sentence for everything else.
- The calendar or job software your crew uses, with access, and the windows you'll release.
- Five example exchanges written the way your best dispatcher talks.
- A phone system that forwards unanswered calls and sends texts.
