FAQ
What does an AI receptionist do for an HVAC company?
It answers your business line 24/7, captures the caller's name, address and problem, books or requests a visit, and escalates emergencies such as no heat or no cooling to the on-call tech by text or live transfer. Several vendors in our list, including OnCrew and Jobber Receptionist, document emergency or urgent-call escalation as a feature.
How much does an AI receptionist for HVAC cost?
Published entry prices among our 17 HVAC vendors start at $10/month (KaiCalls), then $24.95/month (Upfirst, 30 calls) and $49/month (OnCrew, 100 calls; Marlie and Rosie, 250 minutes). Unlimited inbound calls start at $199/month (NextPhone). Three HVAC vendors (Avoca AI, Housecall Pro CSR AI and Jobber Receptionist) do not publish a separate AI receptionist price.
Which AI receptionists work with ServiceTitan?
Is there an AI receptionist for HVAC with a free trial and no credit card?
Yes. On 2026-10-15 we re-read the vendor pages for OnCrew (14-day trial, no card), Upfirst (no card required) and Frontivo.io (14-day trial, no card). Jobber's trial needs no card, but the AI Receptionist may be a paid add-on.
Can an AI receptionist handle emergency HVAC calls after hours?
Yes, if you configure it. Look for emergency triage rules, an on-call alert (text or warm transfer) and a fallback when the tech does not pick up. Test it during a trial with a scripted "my furnace is out and it is freezing" call at night.
Is an AI receptionist better than an answering service for HVAC?
It is usually cheaper and books jobs directly, but a human answering service can handle unusual calls better. Hybrids exist: AgentZap offers live human agent backup. See AI answering service vs AI receptionist.
What an HVAC AI receptionist has to get right
HVAC phones are spiky. A heatwave or the first cold snap can bring a week's calls in a day, and the calls that matter most often arrive at night. Generic answering tools can take messages; an HVAC-ready setup should do four jobs well:
- Emergency triage. Separate "no heat, elderly resident" from "can I book a tune-up next month". You set the rules; the agent follows them.
- On-call dispatch. Text or transfer the on-call tech with the address and problem, then confirm to the caller what happens next.
- Booking into your field service software. If you run ServiceTitan, Housecall Pro or Jobber, a tool that writes to that schedule saves your CSR a re-key.
- Capacity during surges. Check whether the plan is priced per call, per minute or unlimited, because a surge week is when overage bites.

† Added from our vendor data after this guide was written. Details are as recorded in the listing, not summarised by our editors.
Notes from our data: ServiceAgent's site said it "launches soon" with a waitlist on 2026-10-15, so treat it as pre-launch. DialIQ's homepage shows a "$0.30 per-minute, all in" line that conflicts with its per-call pricing page; we list the pricing page. Housecall Pro and Jobber publish platform plans, but not a separate price for the AI receptionist.
Integration snapshot
Two home services vendors outside the HVAC tag also list field service software: LumiTalk (ServiceTitan, Housecall Pro, Jobber, Workiz, JobNimbus, AccuLynx) and AutoRev (ServiceTitan, Housecall Pro, Jobber, Workiz, JobNimbus). Both are quote only.
How HVAC pricing models play out
The same month can cost very different amounts depending on how a vendor counts usage. Using only published numbers, here is a 100-call month:
- Per call: OnCrew Starter covers 100 calls for $49. Upfirst Premium is $59.95 for 90 calls plus 10 extra at $1 = $69.95.
- Per minute: Marlie and Rosie include 250 minutes for $49. Whether 100 calls fit depends on your average call length, which your phone system's call log will show.
- Unlimited: NextPhone is $199 whether you get 100 calls or a surge week of many more.
Setup fees matter too: AgentZap lists a $499 one-time training and setup fee (waived on a 6-month Professional term). For the full cross-industry breakdown, see how much an AI receptionist costs.
Hear them before you sign up
These public demo lines were found on the vendors' own pages on 2026-10-15. Call one at night and play a no-heat emergency.
- OnCrew: (818) 578-4783
- Marlie: (631) 970-4479 (main line)
- Upfirst: (833) 564-4778

- KaiCalls: 1 (802) 232-8873
Numbers change. If one no longer works, tell us via Submit and we will update the listing.
Plumbers and electricians
Plumbing and electrical shops face the same after-hours problem, with burst pipes and power faults in place of no-heat calls.
- AI receptionist for plumbers lists 12 vendors; 12 of them also appear in the HVAC list above. Notable for plumbers: OnCrew (trades-specific emergency triage), Dialzara (from $29/mo).
- AI receptionist for electricians lists 10 vendors; 10 of them also appear in the HVAC list above.
- Roofers have storm surges rather than nightly emergencies. Voka AI documents emergency warm transfers on its roofing page and offers 14 days or 100 minutes free with no card. See AI receptionist for roofers.
If you run multiple trades, the home services page lists 28 vendors.
How to choose: a five-step checklist
- Start from your software. If you live in ServiceTitan, Housecall Pro or Jobber, shortlist vendors that name it, then ask for a live booking demo.
- Pull last month's call log. Count calls and average length so you can compare per-call, per-minute and unlimited plans honestly.
- Write your emergency rules first. Which keywords, times and customer types trigger a transfer or tech text?
- Run a scripted trial. Call after hours, call during a simulated rush, call with a spam pitch, and ask for a price the agent should not quote.
- Check the exit. Month-to-month or annual? Can you keep your number? OnCrew and AgentZap list money-back guarantees; most others rely on trials.
