AI Receptionist for Plumbers · HVAC · Electricians Never lose a job to voicemailvoicemail again.
We answer your calls 24/7 and book jobs straight to your calendar automatically — so you stop losing leads while you're on the job. Up and running in under 48 hours with a 14-day free trial. Keep it only if it's clearly paying for itself.
Every missed call is a
job you'll never know about.
You're on a job. Your phone's ringing. That customer isn't leaving a voicemail — they're calling the next contractor on Google.
62% of callers won't leave a voicemail
They hang up and call the next name on Google. You never find out they called. The revenue disappears without a trace.
After-hours calls are your highest value
Burst pipes, dead AC, power outages — emergencies don't wait for business hours. Neither should your phone coverage.
Phone tag is killing your close rate
You call them back 4 hours later. They already hired someone. The callback game is a game you always lose.
Live in 48 hours.
No tech skills needed.

The AI wears two hats. It books jobs, but it also answers questions about Sinnthetic. Test both:
Built for the trades.

Kenzo Stevens
I built Sinnthetic after watching contractors lose thousands to voicemail every month with no realistic fix at their size. Every system is built personally by me. I'm the person you'll talk to on the setup call, the person who builds your AI receptionist, and the person who picks up when you need something fixed. There's no team you get handed off to. It's me the whole way through. If something breaks, you text me and I fix it.
Now onboarding
contractors.
Be one of the first to try it.
We're actively onboarding plumbing, HVAC, and electrical contractors. Every system is built personally by Kenzo. Limited spots to ensure quality during early rollout.
Things you're probably wondering.
No. It sounds like a professional, friendly receptionist, not Siri reading a Wikipedia article. We train it on your specific business details, your tone, and your services. Callers regularly do not realize they are talking to AI. You will hear every call transcript yourself so you can judge the quality firsthand.
It will not. We build it specifically around your business, your services, your hours, your service area, and your pricing rules. It only says what it has been trained to say. It does not improvise or make things up. It never quotes specific repair prices to customers. It handles the booking and the details, and you handle pricing on the job.
If anything about your business changes, just text Kenzo and we update it within 24 hours at no extra cost.
It handles it gracefully. If a question comes up that is outside what the AI was trained on, it does not guess or fumble. It takes the caller’s name, number, and details, lets them know someone will follow up, and sends you an email summary so you can call them back personally.
Nothing falls through the cracks, and the caller never gets a bad experience.
This does not replace her. It catches everything she cannot.
When she is on another call, the AI answers. When she goes to lunch, the AI answers. When she goes home at 5 PM, the AI keeps answering. Nights, weekends, holidays, sick days, the AI covers it all.
She does her job during her hours. The AI makes sure nothing slips through the cracks the rest of the time. Many contractors use both, a human during business hours and the AI for everything else. It is not either or.
You are in complete control. We set it up however you want. Your phone can ring first with the AI as a safety net, or the AI can handle everything directly and send you a summary.
Your choice. And you can change it anytime.
Absolutely not. We work with your existing business line. It is a simple call forwarding setup. Your number stays exactly the same, and your customers never notice a change.
Just tell us. We update your AI receptionist within 24 hours at no extra cost.
Add a service, change your hours, adjust your service area, it adapts as fast as your business does.
If you love it, and you will, it is $359 per month with no contract.
Cancel anytime with one click. No penalties, no retention calls, no games.
If you decide it is not for you during the trial, you owe absolutely nothing and you keep all your call data.
Right now, yes.
We built this specifically for residential service contractors because that is where we know the pain is deepest and the ROI is clearest. We may expand to other trades in the future, but our focus is on doing this exceptionally well for plumbing, HVAC, and electrical.
