Every missed call is revenue you'll never see again.

A typical $2–$15M HVAC shop misses 20–30% of calls at peak. Most owners don't realize the cost until they add it up.

$6K–$20K

lost per month

Missed-call revenue — $72K–$240K a year disappearing in real time.

5–15

owner interruptions / day

You're on a roof in 95° heat answering calls your office staff couldn't get to.

$80–150K

for an FTE

And a full-time front desk still doesn't cover after-hours, weekends, or holidays.

You can't hire your way out of this. You can't ignore it. Every voicemail is a competitor's invoice.

A 24/7 AI office manager that knows trades.

GreeterHub answers every call in under one ring, books appointments directly into your calendar, and pulls customer history from your CRM mid-conversation.

Knows what a humming compressor means. Triages no-heat calls. Asks the right diagnostic questions for HVAC, plumbing, and electrical.

Books appointments live

Native integrations with ServiceTitan, Jobber, HouseCall Pro, Google Calendar, Calendly, and Acuity. No double-booking.

Syncs to your CRM

Customer history pulls mid-call. Job notes write back natively. No Zapier middleware. No broken integrations.

Founding members lock $199/mo for life.

At public launch, GreeterHub Pro is $349/mo. That's still half of what Smith.ai charges for hybrid coverage — and less than a tenth of what hiring a full-time front desk costs.
