What sucked
The HVAC company was receiving inbound calls from homeowners for services, repairs, and appointments.
Managing these calls manually created several operational problems.
What they built
Hectahash built an AI inbound voice agent that acts as the first point of contact for an HVAC company's calls. It runs on Vapi and Twilio with the OpenAI API, and n8n wires it into GoHighLevel for lead records, appointment scheduling and follow-up workflows.
What changed
40% fewer missed inbound calls
24/7 AI call handling answers calls that used to go unanswered.
2x more qualified leads captured
Automated qualification on every inbound call feeds structured lead records into GoHighLevel.
30% faster appointment booking
Qualification, scheduling and CRM updates run in one automated flow from first call to booked job.
