# HVAC company books 115 jobs in one month with AI texts to past customers

Genz-Ryan, an HVAC, plumbing, and electrical shop in Burnsville MN, let Avoca text past customers and book the job. In month one of Avoca Outbound (October 2026) the AI booked 115 jobs. A furnace tune-up text to roughly 400 to 450 customers booked 70 jobs within a couple of hours. Their unsold-estimate follow-up gets a 36% response rate and a 24% booking rate. They run 40 campaigns.

## Problem

Past customers and unsold estimates sit in ServiceTitan, and nobody sends them a simple offer.

## How to do this

1. Avoca (no public price, talk to sales)
2. A ServiceTitan list of unsold estimates or tune-ups due
3. A small test list (Genz-Ryan started with 70 customers)

## Verdict

One text goes out, the AI answers the reply, and the job lands on the schedule.

## Tools
