From 11pm voicemail purgatory to next-day emergency bookings.

Marcus was losing every after-hours emergency call to voicemail — the customers worth the most. Eight weeks after going live with IzzyOps, after-hours bookings nearly doubled and the on-call tech stopped getting woken up for false alarms.

Situation

The Saturday-night problem.

  • Three trucks, one office manager. Calls between 6pm Friday and 8am Monday went straight to voicemail.
  • Marcus tried an answering service — script was generic, techs got paged for routine questions, customers complained.
  • Estimated 40+ emergency calls per month going to competitors who picked up first.
  • Average emergency callout: $620. Doing the math kept him up at night.
Solution

IzzyOps front-desk, on for 168 hours a week.

  • Custom HVAC persona — knows the difference between "no AC" and "ice on the line" and triages accordingly.
  • Books directly into ServiceTitan. Confirms address, model, payment.
  • Routes true emergencies to the on-call tech with full context — no more 2am "what was that again?" calls.
  • Live handoff to a Redial agent for anything outside the playbook.
Outcome

The numbers, eight weeks in.

  • +92% after-hours bookings (was 34/mo, now 65/mo).
  • −68% calls to voicemail across all hours.
  • $31,200/mo additional revenue, holding net of plan cost.
  • On-call tech pages dropped from ~22/week to 6/week (real emergencies only).
  • Office manager freed up 11 hours/week — now running the recall list.
What we built

A persona that talks like Marcus does.

Most AI voice agents sound like AI. The Marcus' HVAC persona was tuned over two weeks — voice, pacing, the way Marcus says 'we'll get you sorted' — until the team couldn't tell the difference on test calls.

  • Voice + tone reflect Marcus' actual style (warm, plain-spoken, no jargon)
  • Triages on three axes: urgency, complexity, address-in-service-area
  • Books directly into ServiceTitan with the right job code attached
  • Hands off to a real human within 8 seconds when the conversation needs it

Customer story
"Honest answer? I thought it'd be a toy. First week we booked a 2am water heater emergency that would've gone to whichever competitor answered first. That one call paid for the plan twice over. I'm a believer."
