Short answer: The best Smith.ai alternative for a home service business is whichever tool books the job, not just takes the message — and for trades specifically, that means an AI built around dispatch, emergencies, and after-hours calls. Below are seven honest options, including where each one genuinely beats RunBy. You can also just call RunBy's live AI right now and judge for yourself: (786) 733-2209.
Smith.ai is a solid human-plus-AI receptionist service. Owners outgrow it for three reasons: per-call pricing that punishes busy months, message-taking instead of job-booking, and limited after-hours coverage for the trades. Here's the honest landscape as of 2026.
1. RunBy — best for service businesses that want the whole back office, not just the phone
RunBy is an AI employee (not just a receptionist) built for HVAC, plumbing, electrical, and 20+ other trades. It answers every call 24/7 in English and Spanish, books the job into your calendar, triages emergencies, recovers missed calls by text, chases estimates and invoices, and sends a morning briefing. Flat $299/month, no per-call fees. Where it wins: operations breadth and a flat rate that doesn't punish a busy season. Where it doesn't: RunBy is new — there's no decade-long review history yet, which is exactly why the first Florida customers get a half-price founding rate. Test the AI before you believe a word of this: (786) 733-2209.
2. ServiceAgent — best for pre-trained home-services call handling
ServiceAgent's AI is pre-trained on home-services call patterns, so it handles "my AC is broken and I need someone today" well out of the box, with deep CRM integrations and flat-plus-usage pricing. Where it wins: home-services tuning. A genuinely strong option worth comparing against RunBy on price structure.
3. Rosie AI — best budget bilingual answering
Rosie is popular with plumbers, HVAC techs, and contractors for affordable AI answering with generous minute allotments and bilingual support on every plan. Where it wins: low entry price for pure call answering. Trade-off: lighter on the downstream operations (invoicing, review generation, briefings).
4. NextPhone — best flat-rate unlimited for trades
NextPhone offers flat-rate unlimited calls with emergency keyword routing tuned for trades and direct ServiceTitan/Jobber integrations. Where it wins: unlimited-call flat pricing and field-service software hooks.
5. Goodcall — best for very small local shops
Goodcall is an AI phone agent for local service businesses starting around $59/month, focused on inbound calls with location-specific intelligence. Where it wins: lowest entry point for a one-or-two-person shop that only needs the phone answered.
6. Dialzara — best for multilingual communities
Dialzara supports 10 languages with automatic detection — useful for HVAC and plumbing companies serving diverse markets where language barriers cost jobs. Where it wins: breadth of language support.
7. Z360 — best all-in-one communication platform
Z360 bundles AI call answering, an omnichannel inbox, a self-updating CRM, pipelines, and ticketing into one flat-rate platform. Where it wins: teams that want one platform for everything and are willing to migrate their CRM to get it.
How to actually choose
Ignore the feature grids for a second. The only question that matters: when a customer calls at 9pm with a dead AC, does the tool book the job or take a message? A message is a $300/month sticky note. Booking the job is the difference between revenue and a voicemail your competitor never has to compete with.
For a pure receptionist replacement, Rosie or Goodcall are fine. For trades that want the whole back office handled — calls, booking, emergencies, invoicing, reviews — RunBy, ServiceAgent, or Z360 are the real shortlist. RunBy's bet is that you'd rather test the product than read about it: call the live AI and try to break it.
