Key takeaways
- Most demo agents texted a booking link, promised a callback, or transferred me, and several vendors put calendar booking on a higher-priced plan.
- Before you buy, it's worth running the same 3 test calls yourself, covering a booking, a request for a person, and a pricing question.
- Delight.ai was the only AI answering service in my tests that booked a confirmed appointment while I was still on the line.
Here's the short version of my best AI answering service picks, with one line per vendor.
- Delight.ai is best for home service businesses that need every call to end with a booked job.
- Dialzara is best for budget plans that include a live transfer to your team.
- Marlie is best for trades owners who want simple, published monthly plans.
- Smith.ai is best for businesses that want live receptionists backing up the AI.
- Rosie is best for solo owners who mostly need messages taken.
- Frontdesk is best for small teams that want an AI receptionist bundled with chat, texting, and a CRM.
- RingCentral AI Receptionist is best for businesses already running RingCentral phones.
The AI agents that help home service businesses capture missed calls include Delight.ai, Dialzara, Marlie, Smith.ai, Rosie, Frontdesk, and RingCentral AI Receptionist, plus the built-in agents from ServiceTitan, Housecall Pro, and Jobber. I called 7 of them, and only one, Delight.ai's AI booking agent, booked the appointment while I was still on the line.
That gap is the buying decision for an HVAC, plumbing, or electrical company. In a CallRail survey of 601 small and midsized businesses, including home services companies, 87% said they often or sometimes miss prospect or customer calls, and 42% said those calls get missed because people are away from the office. For a contractor, that's the furnace call that rolls to voicemail at 10pm while the crew is on another job, and it's usually the job a competitor books by morning.
The goal is to cover the 10pm call and the July heat wave rush so your CSRs can focus on the callers who need a person. That's the standard I held every agent to.
What does an AI answering service do?
An AI answering service is software that answers your business phone with a conversational AI voice, 24/7, when no one on your team can pick up. The basic versions take a message, while the better ones book the job into your calendar, screen for emergencies, and hand the caller to a person when needed.
Those 4 jobs are where the products separate.
- Answer every call on the first ring, including several at once during a storm or heat wave.
- Book the visit into your schedule while the caller is on the line, instead of promising a callback.
- Triage an emergency, like a no-heat call with a newborn in the house, and route it to your on-call tech.
- Hand off to a person with the caller's details attached, so nobody has to repeat their address.
You'll also see these tools called an AI phone answering service, an AI call answering service, or an AI receptionist. The label doesn't tell you much, since what separates them is how far each one gets through those 4 jobs before it falls back to taking a message.
If you're weighing AI against a traditional answering service for home services, the same 4 jobs make a useful yardstick for both.
How I tested each AI answering service
I called each vendor's public demo line and ran the same 3 tests, covering a booking request, a request for a real person, and a pricing question the agent couldn't fully answer. I've tested AI voice agents this way before, in my ranking of AI voice agents, and the same approach works for answering services.
Most demo lines weren't set up as a home services company, so I kept the tests general. On a vendor's own sales line, booking meant asking for a demo or a meeting with its team, and on a sample business, like a law firm for Smith.ai or an optical store for Delight.ai, it meant booking that business's service.
I scored every agent on 5 criteria.
- Hear it first. Could I call the agent without booking a sales demo or creating an account?
- Booking. Did it book a real slot on the call?
- Handoff. Could it get me to a person when I asked?
- Pricing accuracy. Did its pricing answer match the vendor's own pricing page?
- Voice and response time. Did it sound natural and respond without long pauses or talking over me?
Two vendors, Goodcall and Avoca, didn't offer a way to hear the agent without account setup or a sales demo, so they get their own section after the rankings.
AI answering services compared
Only one of the 7 agents I reached booked the appointment on the call. The table below shows how each one handled the tests, with pricing and G2 ratings from each vendor's own pages and listings.
The scorecard below rolls each test into pass, partial, or fail.
The 7 AI answering services I tested, ranked
If you're looking for the best AI answering service for a home service business, the ranking follows what happened on my calls first, then pricing clarity and independent reviews. Each entry covers what the agent did, what it costs, and who it fits.
1. Delight.ai
Delight.ai is an AI customer agent for support and sales, and it was the only agent in my tests that finished the job on the call. Its public demo is set up as a sample optical store, so I asked to book an eye exam instead of an AC tune-up.
The agent asked whether it was my first visit and which vision plan I had, then quoted my costs for that plan before I asked. It offered 2 real openings, Thursday at 5:30 PM or Saturday at 11 AM, and confirmed the Thursday slot while I was still on the line.
On a second call, I said I had an emergency and needed an appointment right away. The agent screened me first, asking about a sudden change in vision, severe pain, an injury, or something splashed in my eye. When I said my vision had changed suddenly, it told me to go to urgent care or the ER, or call 911, and gave me the address of the nearest urgent care.
That's the behavior a home service business needs on a no-heat call at 10pm. It also sounded the most natural of any agent I tested, with quick responses and none of the talk-over pauses I hit elsewhere.
When I asked for a person, it said it normally can transfer, but not on this demo line, so it offered to add my question to the visit notes for the doctor instead. In a live deployment, Delight Desk, Delight.ai's helpdesk, routes escalations to a human agent with the full conversation attached, so the caller doesn't start over. Delight.ai's AI voice agent is built for background noise, accents, and interruptions, and it responds in under a second.
Dr. Cool Services, an HVAC company in Las Vegas, uses Delight.ai's voice AI to answer every call through peak season, book appointments, and transfer to human agents with full context.
"Our customers don't want to navigate phone trees or wait on hold. They want to talk to someone who can help." Mark Farley, President, Dr. Cool Services, 2026
- Best for HVAC, plumbing, electrical, and other home service businesses that need jobs booked and emergencies triaged on the call.
- Pricing is conversation-based through Delight.ai's sales team, with a $0 seat fee for Delight Desk.
- Rating is 4.7/5 on G2 from 7 reviews.
2. Dialzara
Dialzara is a budget AI receptionist, and its sales agent, Felix, got closer to booking than any agent besides Delight.ai. When I asked about Friday, it said there were no openings, then offered Tuesday at 8:00, 8:30, or 9:00 AM Pacific and started booking the 9:00 slot before I stopped to ask about pricing.
Its pricing answer matched Dialzara's pricing page, from Business Lite at $29 a month for 60 minutes up to Business Elite at $349 a month. It was also the only agent that started a live transfer to a person when I asked.
The call had rough patches. Felix interrupted me several times early on, we talked over each other in a loop, and the voice glitched in places which read as clearly synthetic.
- Best for small shops that want a low entry price and a live transfer option.
- Pricing starts at $29 a month, but calendar sync, after-hours rules, and warm transfers start on Business Pro at $99.
- Rating isn't available, since Dialzara has no G2 reviews.
3. Marlie
Marlie is an AI phone agent built for the trades, and its agent was natural, quick, and informative without pushing me toward a sign-up. When I asked to book a demo for Tuesday, it said it was having trouble accessing the calendar and offered to text me a booking link.
I asked whether that was a glitch, and it said it normally books on the call but was having a technical hiccup. Its pricing answer was close but not exact, quoting 150 minutes on the $49 Basic plan, where Marlie's pricing page lists 250.
- Best for trades owners who want simple monthly plans and a 14-day free trial.
- Pricing starts at $49 a month, but calendar booking and call transfers start on the $99 Standard plan.
- Rating isn't available, since Marlie has no G2 profile.
4. Smith.ai
Smith.ai is an AI and live receptionist hybrid, and its public demo is set up as a sample law firm, so I called as a prospective legal client. The voice sounded natural and responded quickly.
On every call, it asked me to restate my issue, even right after I'd explained it. When I asked to book a consultation about a will, it asked whether my matter involved a car accident, family law, personal injury, or workers' compensation, then took my details for a follow-up instead of booking.
When I asked for a person, it took several tries to agree to a handoff, and after I asked it to hold, it asked what I needed help with as if I hadn't said. It did best when I answered its questions in exactly the order it expected.
- Best for businesses that want live receptionists available behind the AI.
- Pricing for the AI receptionist runs from a free plan with 25 calls a month to $150 a month for 75 calls, and human receptionist plans start at $300 a month.
- Rating is 4.8/5 on G2 from 136 reviews.
5. Rosie
Rosie is a self-serve AI phone answering tool for small businesses, and reaching it took more work than most. Rosie's site didn't list a demo number, and when I asked its website chat agent for one, it asked for my email without answering, then handed me to a person, who gave me the number.
On the call, Rosie agreed to role-play a home services front desk when I asked. It flagged my furnace call as an urgent no-heat call but only promised a team callback, with no time and no next step for a family with a newborn.
When I asked to book a meeting with the Rosie team, it couldn't book or text me a meeting link, and when I asked for a person, it said the line doesn't connect live calls. It also steered back to the free trial and a 50% discount several times.
Its explanation of plans was accurate, though. Calendar booking and live transfers start on the $149 Scale plan, and the $49 Professional plan texts booking links instead, according to Rosie's pricing page.
- Best for solo owners who mostly need calls answered and messages taken.
- Pricing runs $49, $149, or $299 a month, with a 7-day free trial.
- Rating isn't available, since Rosie has no G2 reviews.
6. Frontdesk
Frontdesk, formerly My AI Front Desk, bundles an AI receptionist with web chat, texting, and a CRM. Its agent, Alex, said it would check the calendar, then said it couldn't see the sales calendar and offered to text me a booking link.
The same pattern came up with case studies, where it said it would check, then said it didn't have any. Some answers took so long that I'd normally have asked whether anyone was still there, and it interrupted me a few times.
Its pricing answer didn't match Frontdesk's pricing page. The agent described a $20-a-month basic plan built around chatbot conversations, while the pricing page says phone answering starts at $99 a month, or $79 billed annually, with 200 voice minutes.
- Best for small teams that want voice, chat, texting, and a CRM in one plan.
- Pricing for phone answering starts at $99 a month, with a 7-day free trial.
- Rating is 4.8/5 on G2 from 15 reviews.
7. RingCentral AI Receptionist
RingCentral AI Receptionist works with RingCentral's phone system or as a standalone add-on. The number on its site reached RingCentral's sales line, where an AI assistant answered, so I couldn't confirm it was the AI Receptionist product itself.
When I asked to book a meeting with sales, the assistant asked 2 questions and handed me to a person. It referred to itself only as an AI assistant, with no name or persona, and the chat on RingCentral's site offers a fixed menu of questions instead of a text box.
RingCentral publishes customer results for the product, including one customer whose booked appointments rose from about 6,600 to 7,600.
- Best for businesses already running RingCentral phones that want AI answering added on.
- Pricing starts at $49 a month standalone with 100 minutes, and there's a free trial, according to RingCentral's pricing page.
- Rating is 4.4/5 on G2 from 54 reviews.
Which AI answering services can't you hear before you buy?
The AI answering services I couldn't hear before buying were Goodcall and Avoca, since one requires account setup and the other a sales demo. For a buyer comparing options, a short call to the agent is the fastest way to judge it, so I counted that against both.
Goodcall
Goodcall is a self-serve AI phone agent priced per unique customer instead of per minute, from $79 a month for 100 customers to $299 a month for 2,000. Its "Talk to Gabi" button opens account onboarding, which asks for your phone number and business website before you hear anything. Goodcall has 1 review on G2, with a 3.5/5 rating.
Avoca
Avoca is an AI customer service rep built for home service businesses like HVAC, plumbing, and electrical companies, with ServiceTitan integration and more than 1,000 home services customers. Hearing it requires booking a demo with Avoca's sales team, and Avoca doesn't publish pricing.
Avoca has no G2 reviews yet. If you're weighing the two directly, here's how Avoca and Delight.ai compare.
Already on ServiceTitan, Housecall Pro, or Jobber?
If you already run your business on ServiceTitan, Housecall Pro, or Jobber, its built-in AI agent can book straight into the schedule you use every day. The trade-off is that each one works only inside its own platform and needs an active plan, sometimes on a specific tier or add-on.
- ServiceTitan AI Virtual Agent books jobs using live capacity by job type, location, and technician skills, and a customer quote on ServiceTitan's site puts its booking rate at 80% to 85%.
- Housecall Pro CSR AI answers calls, texts, and chats, books into the Housecall Pro calendar using a customer's service history, and transfers calls based on rules you set.
- Jobber Receptionist answers calls and texts 24/7, books visits, and escalates to you when needed, with sample audio on Jobber's site of it booking a same-day emergency HVAC visit.
ServiceTitan and Jobber both let you call their agents before talking to sales. Pricing for all 3 runs through each platform, so it's worth asking whether AI answering is included in your current tier or billed as an add-on.
Is an AI answering service better than a live answering service?
An AI answering service is better for instant pickup, unlimited simultaneous calls, and booking around the clock, while a live answering service is better when you want a person on every call. Many home service companies use both, with AI covering after-hours and overflow calls while live staff handle the ones that need judgment.
Live services like Ruby and AnswerConnect put a trained receptionist on every call, 24/7. Ruby sells plans by receptionist minutes with the same features on every plan. AnswerConnect quotes minute-based plans after you request pricing.
The limit with live answering is what a receptionist can do inside a script and a staffing plan. Whether a live agent can book directly into your schedule, or just takes details and passes them along, depends on how the service is set up and how many calls hit at once during a heat wave.
Hybrid services split the difference. Smith.ai, for example, sells AI-first, hybrid, and human-first plans, so the AI handles routine calls and a person steps in when needed.
The useful question isn't AI or people. It's which calls need a person, and whether your answering service can get those callers to one quickly with their details intact, the same trade-off that comes up when choosing an HVAC answering service.
How do you choose an AI answering service for a home service business?
Choosing an AI answering service for a home service business comes down to calling the agent a few times before you sign anything, including an emergency scenario if the demo line supports it. Pricing pages and feature lists tell you what a plan includes, but only a call shows you what the agent does when a caller goes off script.
How should it handle an after-hours emergency?
A good agent should handle an after-hours emergency by screening before it books. For a no-heat call in January, that means asking whether anyone at home is at risk, then routing the call to your on-call tech or giving the caller a clear next step instead of a vague callback. An agent that only takes a message leaves the caller with no idea when help is coming.
Which plan tier includes booking and live transfer?
Booking and live transfer usually sit on a higher plan tier than the entry price. Rosie's calendar booking starts at $149 a month, Marlie's at $99, and Dialzara's calendar sync at $99, so the entry price often covers message-taking and texted links only. It's worth checking which tier your call flow needs before comparing prices.
Can you hear it before you talk to sales?
You can hear most of these agents before you talk to sales, and a public demo line lets you judge voice quality, response time, and how the agent handles an interruption in a few minutes. Of the vendors I looked at, Goodcall required account setup and Avoca required a sales demo, while ServiceTitan and Jobber both offer a line you can call. Several of these vendors also have little or no review history on G2, which makes a test call even more useful.
Here's the short checklist I'd use on any demo line.
- The emergency call, to see whether it screens, escalates, and gives a next step.
- The booking call, to see whether it confirms a real slot or sends a link.
- The request for a person, to see how fast the handoff happens and whether your details carry over.
- The pricing question, to see whether its answer matches the vendor's own pricing page.
A missed call at 10pm is a job a competitor books by morning, and most of the agents I tested still answer that call with a message or a link. The ones worth paying for book the visit, triage the emergency, and get the caller to a person when it counts. See how Delight.ai answers and books calls, from the first ring to the confirmed appointment.
