Twelve questions to ask before you buy an AI receptionist
The category is crowded and the demos are polished. These are the questions that separate a working product from a good sales call — including the ones we find awkward.
There are a lot of AI receptionist companies now, and the demos are all impressive. That is the problem — a scripted demo is designed to be impressive, and it tells you almost nothing about what happens on a real Tuesday in July when a caller interrupts, mumbles an address and asks if they are talking to a robot.
These are the questions worth asking. Some of them are awkward for us to answer too, and we have marked those honestly.
Before anything else: dial it
If a vendor will not give you a phone number you can call yourself, right now, without booking a meeting — stop. In a voice product, refusing to let you hear the voice is disqualifying.
When you do call, do not be polite. Interrupt it mid-sentence. Change your mind about the appointment. Give a partial address. Ask what it charges. Ask if it is a robot. Go quiet for ten seconds. The scripted path always works; you are looking for what happens off it.
The twelve questions
1. Does it book, or does it take a message? The dividing line in the whole category. “Handles your calls 24/7” can mean either. Ask specifically: can it write to my calendar during the call? If the answer involves “relay” or “notify you”, it is a message service with better marketing.
2. Which calendar and field service platform does it write to? Google Calendar, Cal.com, Jobber, Housecall Pro, ServiceTitan. If it does not integrate with what you already use, someone is going to be re-typing appointments, which erases most of the benefit.
3. What happens on the eleventh simultaneous call? The main structural advantage over humans. Confirm there is no concurrency cap on your plan, and ask what happens if you exceed it.
4. Is the pricing metered? Per-minute or per-call pricing bills you hardest during the weeks you are busiest. Model any quote against your peak week, not your average. Here is how the tiers compare.
5. Will it admit it is AI when asked? It must. A voice agent that denies being AI is a legal and reputational problem, not a feature — and some US states have disclosure requirements for automated commercial calls. Ask to hear it answer the question. More on the compliance basics here.
6. What does it do in a genuine emergency? Gas smell, carbon monoxide, smoke, active flooding. The correct behaviour is to stop the booking flow, tell the caller to leave and call 911, and escalate to a human immediately. If the answer is “it books an appointment”, walk away.
7. Can it quote my diagnostic fee, and my waiver rule? This is the single most common question on an HVAC call and the most common place calls are lost. It needs your exact fee and your exact policy. Why the phrasing matters.
8. How long is onboarding? Some platforms need two to four weeks of scripting. If you are buying in June because you are drowning, that means help in July. Ask for a go-live date in writing.
9. What do I get after the call? Recording, transcript, structured summary, outcome. Without these you cannot audit it, cannot improve the script, and cannot tell whether it is working. If a vendor cannot show you a real call log, they are showing you a demo, not a product.
10. How do I turn it off? Coverage should be a forwarding rule you control, not a port. If switching off requires a support ticket or a notice period, you are not in control of your own phone line. How forwarding actually works.
11. What is the trial, and what does it cost me if I hate it? The strongest structure is after-hours only, because it cannot touch a call you are already answering — the worst case is that your voicemail carries on as usual. Be wary of trials that require a full cutover on day one.
12. Who owns the data? Your call recordings and customer details are your customer list. Ask what happens to them if you cancel.
The three questions we find awkward
Fair is fair.
“How many HVAC clients do you have?” We are early. We would rather tell you that than invent a customer count. What we have instead is a live demo line you can test in ninety seconds and pilot pricing for the first shops who work with us — and we would rather earn a case study than borrow one.
“What happens if the AI gets it wrong?” It will, occasionally. Every system does, including human CSRs. The honest answer is not “it never fails” — it is that you get the recording and transcript of every call, so you can see exactly what happened and we can fix the behaviour. Any vendor claiming a zero-error rate is describing a demo, not a deployment.
“Will my older customers hate it?” Some will. That is a real preference, not an objection to overcome. Which is why we think the sensible deployment for most shops is a human on the daytime and complex calls, with automation behind them for overflow and after-hours — the hybrid, not the replacement.
The single test that beats all twelve
Forward your after-hours line to it for two weeks and count the bookings.
Not the demo. Not the deck. Not the reference calls. Your line, your customers, your calendar, for fourteen days. Every question above matters, but they are all proxies for the one thing you actually care about: did jobs appear on the schedule that would not otherwise have been there.
If a vendor is confident, they will make that easy. If they are not, the twelve questions above will usually reveal why before you find out the expensive way.
Ours is (260) 264-9632. It answers as a fictional HVAC company called Summit Plumbing and Air. Be as difficult with it as you like — that is genuinely the point, and it will tell you what it is if you ask.
