Hi — my AC stopped working. It's 98 degrees and I have two kids at home.

Got it, Maria. Best number to reach you?

Eva — Callivox
Six, zero, two… five, five, five… zero, one, eight, three — right?
Homeowner
Yes, that's it.
Eva — Callivox
And what ZIP code are we coming out to?
Emergency detected — no AC, extreme heat, children present
Checking service area against customer ZIP…

The calls you can't answer
are often the jobs you lose.

HVAC calls arrive while you're on a roof, in a crawl space, driving between jobs, or working around a running condenser. Most callers don't leave a voicemail — they call the next contractor on the list. Callivox answers immediately, every time.

Setup

Three steps. Under ten minutes.

01

Forward your number

Your existing business number. Your existing carrier. No new hardware, no new phone line. Takes two minutes.

02

Eva takes the call

Answers with your business name. Collects what she needs. Works through your business rules — service area, hours, emergency handling.

03

Job lands on your calendar

Booking syncs to Google Calendar instantly. Customer gets a text or email confirmation. You get back to the job you're on.


Capabilities

What generic booking tools don't do.

Emergency triage

Urgency signals, handled differently

When a caller says "no AC," "no heat," "gas smell," or mentions extreme temperatures, Eva shifts mode immediately — prioritizing speed over the standard booking flow. A routine tune-up request and a no-cool emergency are not handled the same way.

"My AC stopped working and it's 101 degrees" → emergency path, earliest slot, flagged in calendar

Service-area validation

No jobs booked outside your coverage

Every caller's ZIP code is checked against your service area before a booking is confirmed. Out-of-area calls get a polite decline with the caller's details still captured. You'll never dispatch a technician two hours for a job you shouldn't have taken.

ZIP outside coverage → "I'm sorry, that's outside our service area — I've noted your details and we'll reach out if coverage expands"

Address readback

Address confirmed before dispatch

Before any booking is confirmed, Eva reads the full service address back to the caller and waits for explicit confirmation. A misheard address means a wasted dispatch. This step eliminates that before it happens.

"Let me confirm — 4821 West Cactus Drive, Phoenix. Does that sound right?"

Noise resilience

Built for callers on job sites

Customers call from running condensers, mechanical rooms, and loud job sites. Eva handles real-world call conditions — not just a quiet office environment. Your callers don't need to step outside to book a service call.


Who Callivox is for

Built around an HVAC call.
Not adapted to one.

Some AI receptionist platforms are designed for large, multi-location operations with dedicated IT staff and complex CRM integrations. Callivox is designed for the owner-operator or small dispatch team that needs calls handled immediately — without an IT project to set it up.

FAQ

Questions contractors ask.

No. You keep your existing number. You forward calls to Callivox — either always, or only when you're unavailable. Works with any carrier.
Eva sounds natural and conversational, not robotic. Most callers experience it as a helpful receptionist. You can configure it to identify itself as a virtual assistant if you prefer.
Eva detects urgency from the first sentence — "no heat," "no AC," extreme temperatures, gas smell. It shifts to a faster flow, prioritizes the earliest available slot, and flags the booking as urgent in your calendar. A heatwave no-cool call is never treated like a spring tune-up.
During setup you provide your service ZIP codes. Every caller's ZIP is checked before any booking is confirmed. Out-of-area callers get a polite decline — their details are still captured in case your coverage ever expands.
Yes. If a caller asks for a human, Eva lets them know someone will call back shortly, captures their details, and logs everything. You get the complete record when you're free.
Google Calendar. Every confirmed appointment appears the moment the call ends — with the customer's name, number, address, job type, and any notes from the call. Nothing to re-enter manually.
Under 10 minutes. Business name, service ZIPs, working hours, weekend policy, forward your number. Done. During the beta we also do a brief walkthrough call to make sure everything is configured correctly for your business.
During the beta, Callivox is completely free. No credit card, no contract. When we launch commercially, pricing will be flat monthly — no per-call overages, same bill regardless of call volume. Beta contractors will hear about pricing before anyone else.
Eva reads the full address back before confirming. If the caller corrects it, Eva re-reads the corrected version and confirms again. The booking doesn't hit your calendar until the address is verified.
Yes. Callivox handles real-world calling conditions — running condensers, mechanical rooms, job site noise. Your callers don't need to find a quiet room to book a call.
We're launching with HVAC first. Plumbing and electrical are next — with the same trade-specific depth, not a generic adaptation. If you run one of those trades and want to be notified, email hello@callivox.ai.
