The Problem

What was costing them before Katexs.

  • Averaging 27 missed calls per week — all after 5pm and weekends.
  • Lost a $3,200 job to a competitor who picked up at 7pm on a Tuesday.
  • Owner manually checking voicemail every morning and returning calls between jobs.
“I went from missing 4 calls a day to zero. The AI receptionist went live in 3 days and paid for itself in week one.”
The Katexs Build

What we built — step by step.

We built a full inbound voice agent on Vapi with a custom ElevenLabs voice tuned for the HVAC industry. The agent qualifies the caller, books a slot, and writes a contact into CRM with full transcript. Twilio number provisioned and ported, GHL connected, tested on real calls — all in 3 days.
