7 Questions to Ask Before Buying an AI Receptionist
A buyer checklist for HVAC, plumbing and electrical shops: seven questions that separate a real AI receptionist from a voicemail upgrade.

The demo call is polite. The voice is calm. The agent books "Tuesday morning" with confidence. Your real Tuesday is different: two lines ringing, a chat tab blinking, a caller who talks over the greeting, and a calendar with one gap left. That is the call that decides whether you bought coverage or a novelty.
Ask these seven questions out loud. Write the answers. Compare vendors on the same sheet. Category buyer guides keep saying the same thing because operators keep getting burned: make a live test call yourself, demand real calendar booking, and pin down escalation and pricing before you forward the main number.
1. Do voice and web chat share one memory?
If the phone product and the website widget are cousins that do not talk, customers will restart their story. Ask for a proof: say a detail on the call, then continue in chat five minutes later. If the agent asks again, that is a hard fail.
2. Will it book against my real openings?
Message-taking is voicemail with better manners. Ask whether the agent checks live availability for your service model (field, shop, or hybrid) and writes a real appointment. "Someone will call you back" is not a booking. It is a delay with confidence.
3. What happens when the answer is not in the script?
You need a knowledge base and service catalog you control. Then ask what the agent does when it does not know: escalate, capture a structured lead, or invent a policy. Inventing coverage areas or prices is how reviews get written about you, not the vendor.
4. How fast is the first syllable?
Awkward silence feels like a scam call. Service Socket targets about half a second on inbound voice. Whatever you buy, test it on a phone in a truck, not a headset in a quiet office. If you flinch at the lag, your callers will hang up.
5. Who owns the handoff to a human?
You set the rules: emergency, VIP, angry caller, price exception, "send a human now." Ask whether context travels with the handoff. A cold transfer that makes the customer repeat everything erases the reason you bought AI in the first place.
6. What is Starter versus Pro, in one sentence each?
Force a plain split. Answering and booking is one job. Outbound SMS, AI follow-up calls, dispatch suggestions, and a back-office agent are another. If the vendor cannot draw the line without a slide titled "flexibility," your invoice will invent fees later.
7. Can I see what happened overnight?
Transcripts, recordings where appropriate, and a clear report of booked versus missed turn Monday into a review. A text that only says "you had 14 calls" is not an operations tool. It is a guilt trip.
How to run the bake-off
Shortlist three vendors. Call each demo line twice: once with a clean booking request, once with an interruption and a service-area edge case. Send the same chat question to each widget. Score 1 through 7. Drop anyone who fails booking or shared context, even if the voice sounds expensive.
Want the cost side first? Estimate what unanswered calls are worth for an HVAC company or a plumbing shop, then build the shortlist from the alternatives hub.

Frequently asked questions
What should I ask an AI receptionist vendor?
Ask whether voice and chat share one memory, whether it books against real openings, what it does when the answer is not in the script, how fast it responds, who owns handoffs, how the plans split, and what reporting you get.
How do I test an AI receptionist before buying?
Call the demo line from a cell phone twice: once with a clean booking request and once with an interruption and a service-area edge case. Send the same chat question to each vendor and score every answer on one sheet.
What is the difference between an AI receptionist and an answering service?
A traditional answering service uses people to take messages or book. An AI receptionist answers with software first, and some vendors mix both. The useful difference is whether the result is a booked job or a message someone still has to return.
How much does an AI receptionist cost?
Pricing ranges from self-serve monthly tiers to per-minute and enterprise contracts. Service Socket publishes Starter at $99/mo with 500 AI credits and Pro at $299/mo with 2,500, with metered overage beyond the pool.
