An AI receptionist for heating, plumbing and electrical firms

Your callers are standing in the problem — a cold house, water where it should not be, a tripped board. They want somebody coming, and a straight answer about when.

what the phone is costing you

Five missed calls a week, at a $340 job, is about $32,640 a year — if 60% of those callers wanted to book and 60% of them never ring back.

Trades lose more revenue to the phone than any other business on this list, for one structural reason: you cannot answer it. You are under a sink, on a roof, or driving. Meanwhile the caller with a leak is working down a list of numbers and stopping at the first one that picks up.

And what that number is not →

It already knows how your callers talk.

“No heat” vs “no hot water”
Different faults on the same boiler. It notes which, because the engineer needs to know before they arrive.
“A leak”
It asks whether it is a drip they can catch in a bowl or water they cannot stop. The second is an emergency, and it treats it as one.
“The electrics tripped”
Half the sockets off is a fault. A burning smell from a socket is an emergency, with a different answer.
“Just a ballpark?”
Repair prices depend on what the engineer finds. If you list a call-out or diagnostic fee, it quotes that and only that.

A call it takes while you are busy

Incoming callwhile you were working

“I've got water coming through the kitchen ceiling.”

“That is one to deal with now rather than book in. First — do you know where your main water shut-off is? Turning the water off will stop it getting worse while we get to you.”

“Yeah, I've turned it off already.”

“Good. I am flagging this as an emergency and someone will call you back within minutes. Can I take the address and a number to reach you on?”

What is waiting for you afterwards

  • An emergency message, raised immediately rather than sitting in voicemail — a callback row with the number on it, open until somebody clears it.
  • The address and number captured, so the callback takes ten seconds.
  • Everything else that came in today — the quotes, the routine jobs — waiting in order.

What it writes down without being asked

  • The full address of the property. A job without an address cannot be dispatched, and it does not end the call without one.
  • A working phone number, read back and confirmed.
  • The problem in the caller's own words — what is happening, since when, and anything they have already tried.
  • Access details they volunteer: keys, tenants, parking.

Gas, carbon monoxide, water and wiring

A smell of gas or a CO alarm gets the safety instruction before any booking talk — out of the property, no switches or flames, then 911 and the gas company from outside. Water they cannot stop gets the main shut-off valve; scorching or sparks get the circuit switched off at the breaker panel where it is safe to reach. Then the urgent message.

the part nobody else prints

What it will never do

  • Quote a repair price for a fault nobody has seen.
  • Treat water somebody cannot stop, or a burning smell, as a routine booking.
  • Book a slot next week for a home with no heat in freezing weather and a baby or an elderly person in it.

These are hard limits in the brief your agent runs on — not a tone setting you can turn off by accident.

The questions your callers actually open with

  • “My boiler's stopped and I've got no heating.”
  • “How much do you charge for a call-out?”
  • “There's water coming through my kitchen ceiling.”
  • “Can someone come out today?”

Whatever your diary is

Trades rarely run booking software. This is a phone number that answers while your hands are full, structured job requests you confirm with one tap from the van, and a connected calendar so it never offers a morning you have already committed. It also rings out: confirm tomorrow's appointments, or tell a customer the part arrived.

Questions owners in your industry ask

Can it quote a job over the phone?

It quotes your call-out fee and your hourly or fixed rates — the figures you set. It will not price a job it cannot see, because a number quoted on the phone and contradicted on the doorstep costs you the job and the goodwill.

Does it know what counts as an emergency?

Yes, in the vocabulary of the trade: a leak, no heat in winter, a gas smell, an electrical fault, no water. Those stop being bookings and become urgent messages, and it reads back your own emergency instruction — including telling somebody with a gas smell to get out and call 911 rather than waiting for you.

Can it call people back for me?

Yes. Write a note — “tell him the part arrived, we can fit him Thursday” — and it rings them from your own number and reports what they said. It also confirms tomorrow's jobs by phone so you are not driving to an empty house.
