For an HVAC or plumbing company, the after-hours phone is a sorting problem. Some of those calls are real emergencies worth a premium dispatch, some are customers who want to be first in line tomorrow, and some are people asking whether you install water softeners. A voicemail treats all three the same, which means you lose the first kind and your on-call tech gets woken up by the third. An AI receptionist solves this only if it triages with rules you wrote, escalates to a human on the calls that deserve it, and never plays technician.
Here is the triage model we set up for trade businesses, what the receptionist says, and where it hands off.
Three tiers, written by you
Before the receptionist takes a single call, the owner or dispatcher answers one question for each common situation: does this get a tech tonight, a first-thing callback, or a normal-hours callback? The answers become the rules. A typical plumbing set looks like this:
Tier 1, dispatch tonight. Active leak that cannot be shut off, sewage backup inside the home, no water to the whole property, a burst pipe, water near electrical. For HVAC: no heat with an infant or elderly person in the home during a cold night, no cooling during a heat advisory for a medically vulnerable person, a suspected gas smell (which is a 911 and gas-company call first, not a dispatch).
Tier 2, first-thing callback with a flagged brief. A leak the caller has managed to shut off, one non-working bathroom in a house with another, a water heater that is out but not leaking, an AC that is struggling but running, a furnace short-cycling.
Tier 3, normal-hours callback. Estimates, new installs, maintenance plans, a dripping faucet, "how much do you charge," and anyone calling about a job already scheduled.
The receptionist asks the questions that separate the tiers: Is water still coming out? Can you find the shutoff? Is anyone in the home at risk from the temperature? Do you smell gas? It does not decide what the problem is. It decides which of your three rules applies.
What the receptionist says on a Tier 1 call
The goal on a real emergency is speed and one clear action for the caller. A good exchange sounds like this:
Caller: There's water pouring out from under the kitchen sink and I can't get it to stop.
Receptionist: I'm going to get someone to you tonight. First, is there a shutoff valve under the sink, usually a small handle on the pipe? If you can turn it clockwise, do that now. If not, the main shutoff for the house is usually near the water meter or where the pipe enters the house. Are you able to reach either one?
Then name, address, callback number, and a confirmation read-back. Then one of two things happens, depending on how you configured it.
Handoff on. The receptionist tells the caller it is connecting them to the on-call technician and transfers the live call to the number you set in the portal. The tech gets the caller on the line plus, seconds later, the brief by email or text with the address already captured. If the tech does not pick up, the receptionist takes the call back, tells the caller the tech has been alerted, and confirms the callback number.
Handoff off. The receptionist tells the caller that the on-call technician has been alerted and will call within the window you set, and the urgent alert goes to the on-call cell as a text and email with the address, the problem, and the callback number.
Most trade businesses run handoff on at night and off during the day, when the dispatcher is at a desk anyway.
What it never says
The single most important rule for a trades receptionist is the same as for a law office or a clinic: it does not give professional advice. It can walk a caller to a shutoff valve because that is a safety instruction you approved. It does not say "it's probably the thermocouple," "you can leave that overnight," or "that sounds like it's covered under warranty." When a caller pushes, it says plainly: "I can't tell you what's causing it, but the technician can when they call."
Pricing is the second boundary. It shares only what you tell it to share, such as your after-hours dispatch fee and whether estimates are free. It does not guess at what a repair will cost.
Why the brief matters more than the answer
A dispatcher's real complaint about voicemail is not that the call was missed. It is that the message says "hey it's Mike, call me back, it's about the heater" with no address, no callback number, and no clue whether it is a Tier 1 or a Tier 3. Every call the receptionist takes produces a brief that reads like a dispatcher wrote it:
URGENT, Tier 1. Dana R., 4118 Vernon Ave, (213) 555-0197. Active leak under kitchen sink, caller shut off the under-sink valve, water is stopped but the cabinet is soaked. Wants someone tonight. English. Transferred to on-call at 1:52 AM, connected.
That is the difference between a tech who leaves the house knowing what tools to bring and one who calls back first to ask.
Bilingual, because your customers are
A large share of after-hours calls in Los Angeles come from Spanish-speaking households, and in an emergency people reach for their first language. The receptionist handles the whole call in Spanish, walks the caller to the shutoff in Spanish, and marks the brief so your tech knows which language to use at the door. If your crew includes Spanish speakers, this alone changes which jobs you win at night.
Setting it up
You keep your number. Your carrier or phone system forwards unanswered, busy, and after-hours calls to the receptionist; during the day your dispatcher answers as usual. Setup takes about a week, most of which is us turning your triage rules into the questions the receptionist asks, and the last step is a round of test calls with you playing the customer, including a fake 2 AM leak.
Frequently asked questions
Can it dispatch a tech directly, without transferring? It can alert the on-call number by text and email with the full brief, which is what most companies mean by dispatch. Live transfer is optional and turned on per office in the portal.
What if the on-call tech's phone is off? On a live transfer, the receptionist waits for the pickup; if there is none, it takes the call back and confirms the caller's callback number, and the alert still goes out. Nobody gets dropped.
Can we change the tiers seasonally? Yes. A "no cooling" call is Tier 3 in January and can be Tier 1 during a heat advisory. The rules are text you can update, and we adjust them with you.
Does it handle calls about existing jobs? Yes. It takes the name, address, and question, marks it as an existing customer, and routes it to the office for a normal-hours callback. It does not reschedule jobs on its own.
How much does an after-hours call cost us in minutes? An emergency intake typically runs three to five minutes. Most companies forwarding only missed and after-hours calls stay within the 300 minutes included in the plan.
