AI Voice Agents & Workflow Automation for Local Businesses
Missed call = missed job. I built an AI voice receptionist for HVAC companies that answers every call, books the appointment into Google Calendar, and saves the lead in Google Sheets. Watch the real test call on my profile then try it yourself: call +1 (469) 898-0563.

A real test call with the AI voice receptionist I built for HVAC companies.
The caller asks for an AC tune-up, and the agent handles the whole call on its own: it greets the caller, collects his name, phone number and service address, checks Google Calendar for a free slot in real time, books the appointment, confirms the time out loud, and logs the lead automatically.
Built with Vapi (voice agent) and n8n (workflow automation), connected to Google Calendar and Google Sheets.
This is a test call with a dummy customer — no real customer data.
Try it yourself: call +1 (469) 898-0563 and book a test appointment.

Vapi Voice Agent — HVAC Appointment Booking Demo
I configured this AI voice agent in Vapi to collect caller details and handle appointment booking conversations. It connects with n8n workflows to check Google Calendar availability, create appointments, and save caller information in Google Sheets.
This is the voice agent component of my independent HVAC demo, deployed on a US phone number.

Google Calendar Booking — HVAC AI Voice Agent Demo
A test appointment created through my AI voice agent booking workflow using Vapi, n8n, and Google Calendar.
This showcases the calendar integration component of my existing HVAC demo, not a separate client project.
