The Problem: Missed Calls = Lost Revenue

Wayne Conn runs a residential plumbing and heating company with 5 plumbers and 1 office manager. They're good at what they do — 4.8 stars on Google, 20+ years in business.

But they had a problem that was costing them serious money.

Emergency calls don't wait. When a customer has a burst pipe at 9pm, they don't leave a voicemail and wait until morning. They call the next plumber on Google. By the time Wayne checked voicemail the next day, the job was already done — by a competitor.

Wayne tried an answering service. $300/month for humans who took messages. The problem? They couldn't tell the difference between "I need a quote on a bathroom remodel" and "water is flooding my basement RIGHT NOW." His on-call plumber was getting woken up at 3am for non-emergencies.

The Math That Made It Urgent

❌ Before
  • 60% call capture rate
  • 3-5 missed emergency calls/week
  • $300/month answering service
  • On-call plumber woken for non-emergencies
  • No visibility into call quality
✓ After
  • 100% call capture rate
  • Zero missed opportunities
  • AI qualifies emergency vs routine
  • Emergencies routed instantly
  • Full transcripts + recordings in CRM

The Solution: AI That Knows Plumbing Emergencies

We built an AI voice agent specifically trained to handle plumbing calls. Not a generic chatbot — a system that understands the difference between "my toilet is running" and "water is coming through my ceiling."

Route/Schedule

The Qualification Script

The AI asks 7 questions designed to identify true emergencies:

  1. "What's going on? Describe the issue."
  2. "Is water actively leaking right now?"
  3. "Do you have a shut-off valve you can access?"
  4. "Is this affecting your ability to use water in the home?"
  5. "What's your address?"
  6. "What's the best callback number?"
  7. "Does this need someone tonight, or can it wait until morning?"
🎯 Key Insight

Question #2 is the critical one. "Is water actively leaking?" separates real emergencies from everything else. If yes → instant escalation. If no → schedule for next day.

The Routing Logic

The Results: 18 Days to Payback

"Our customers don't care it's AI at 2am — they care someone answers. We've recovered every missed opportunity and my on-call guy actually sleeps through the night now."
Wayne Conn, Owner

After 90 days of running the system:

Payback period: 18 days. The system cost $1,497 to set up + $297/month. Wayne recovered that in the first three weeks from calls that would have gone to competitors.

Why This Works for Home Services

Plumbing, HVAC, electrical, pest control — they all share the same problem:

AI solves this because it never sleeps, never gets tired, and can be trained to ask exactly the right questions for YOUR business. Wayne's AI knows plumbing. An HVAC company's AI would know heating and cooling. Same technology, different expertise.

What We'd Do Differently

After running this system for 90+ days, a few lessons learned:

Losing Calls After Hours?

If you're in home services and missing calls when you can't answer, let's talk. Same system, customized to your business.
