Missed Calls

When your crew is in the field, calls go to voicemail. Those callers don't leave messages — they call your competitor.

~10 missed calls/day
⏱️

Slow Quotes

You're spending 2+ hours a day doing free estimates by hand. That's 500+ hours a year you could spend on revenue-generating work.

Dead Leads

5-15% reactivation rate

★★★★★
We were missing 8-12 calls a day and had no idea. Within the first month of going live, we booked 34 new jobs that would have gone to voicemail. The AI receptionist paid for itself in the first week.

I used to spend two hours every morning writing up estimates. Now the AI quoting agent handles it in seconds and customers get a price before they hang up. My close rate went from 30% to over 50%.

Onyx ran their reactivation agent on 600 dead leads in our CRM. We got 47 callbacks and closed 19 jobs in the first two weeks. That was revenue we completely wrote off.

Straight answers. No BS.
Everything HVAC and plumbing owners ask us before getting started.
Will my customers know they're talking to AI?
Our voice agents sound natural and conversational — not robotic. Most callers don't realize they're speaking with AI. But we can also have the agent introduce itself as a virtual assistant if you prefer transparency.
What if the AI gets something wrong?
We train every agent specifically on your business — your services, your prices, your availability. There's a 3-5 day pilot period where we test and refine before going live. Plus, the agent knows when to transfer to a human for complex situations.
How long until it's up and running?
Most agents are live within 1-2 weeks. Simple agents like review collectors take 3-5 days. We handle everything — you just give us access to your systems and answer a few questions about your business.
What does it cost?
Every project is custom-quoted based on your specific needs. We'll walk through everything in your free audit — no surprises, no hidden fees.
Can it work with my existing phone system?
Yes. We integrate with virtually any phone system, CRM, and calendar tool. If you're using ServiceTitan, Housecall Pro, Jobber, or even just Google Calendar — we'll plug right in.
What if I want to cancel?
There are no long-term contracts and no lock-in. If at any point you want to stop, just let us know with 30 days notice. Simple as that.
