You can't answer the phone from a rooftop, and most callers won't leave a voicemail. They call the next name in the search results. That's the whole case for an AI receptionist. This guide covers what the options actually cost in 2026, where AI beats a human answering service (and where it doesn't), and the seven things to check before you trust anything with your phone line.
For an HVAC or plumbing shop, an average repair call is a $350+ job, and emergency and replacement calls run far higher. A caller with a dead AC in July is not patient: if you don't pick up, the next company on the list gets the job, and often the customer for life. Miss a handful of calls a month and you've quietly lost more revenue than any software line-item on this page. That's the number to hold in your head while comparing prices below.
| Option | Typical cost (mid-2026) | What the caller gets | What you get |
|---|---|---|---|
| Human answering service | $255+/mo, often per-minute on top | A polite person who takes a message | A callback list for after dinner |
| Standalone AI receptionist | $149–500/mo | Instant answer, Q&A, usually a message or a calendar link | Transcripts; scheduling integration varies by product |
| AI receptionist built into your field-service software | $49/mo (FieldForge Front Desk: 100 min included, 45¢/min after) | Instant answer 24/7, your prices and hours quoted, a booked appointment + confirmation text | The job on your schedule, assigned and confirmed, plus every call recorded & transcribed |
Market prices from public sources and published reviews as of July 2026, confirm current rates with each vendor. Front Desk requires a paid FieldForge plan and is in invite-only beta.
Your phone line is your business. Whatever product you're evaluating (ours included) put it through this list.
You should never have to reprint trucks and door magnets. The right setup gives the AI its own line and forwards missed or after-hours calls to it with a single carrier code, reversible in under a minute.
The single biggest divider. Ask: "when a caller wants Tuesday morning, does it check my technicians' actual availability and book the slot?" If the answer involves "a message" or "a link," you're buying an answering machine with better grammar.
It should quote your service-call fee, know your hours and service area, and ask the triage questions of your trade, system age and brand for HVAC, "gas smell means hang up and call 911" for safety. Generic scripts create callbacks, not bookings.
Some callers want a person. That's fine and the AI should embrace it. Check that it can transfer live to your cell or office on request, not trap the caller in a loop.
Trust is earned by audit. You should be able to read or listen to every call it took, especially in the first weeks. If a product hides its transcripts, ask yourself why.
A booking the customer isn't sure happened is a no-show. The service should text the caller a confirmation with date, time and address, and notify your tech.
Per-minute billing is fine; surprise bills are not. Look for a published overage rate and a live usage meter, so month three costs what month one did.
A typical booking call runs about three minutes: greeting, triage questions, a time agreed, done. So a 100-minute plan covers roughly 30 answered calls a month, which for most 1–5 tech shops is every call that currently hits voicemail. If even one of those thirty turns into a $350 repair you'd otherwise have missed, the service has paid for itself seven times over. That arithmetic (not the AI novelty) is why this category is growing.
Honesty corner: if your call volume is heavy with complex commercial negotiations, multi-property management companies, or callers who need long hand-holding, a trained human CSR is still better, and at that volume you can probably justify hiring one (a part-time office hire runs far more than any option above, but does far more than answer phones). The AI receptionist sweet spot is the small shop where the owner is the receptionist, from a ladder, badly.
Standalone services run roughly $149–500/month as of mid-2026; human answering services start around $255/month. FieldForge Front Desk, built into the field-service platform, is $49/month with 100 minutes included and 45¢/minute after.
Depends on the product; most take messages. One integrated with your scheduling software can check real tech availability, book the slot while the caller is on the line, and text a confirmation.
No. Keep your published number; forward missed calls to the AI's line with a carrier code you can undo anytime.
For message-taking warmth at $255+/month, human. For instant 24/7 answers that end in a booked job at a fraction of the price, AI. Just review the recordings and transcripts while it earns your trust.
