- After deploying an AI front desk agent, call capture went from 30% to 100%

This case study follows a 5-person plumbing company in the Dallas-Fort Worth area that deployed an AgentErgon Front Desk Agent and tracked results over 90 days. The patterns we observed are common across Dallas plumbing companies dealing with high call volume and on-site technicians.
The Problem
The company had 4 technicians and 1 owner who also worked jobs. When all hands were on-site, the phone went to voicemail. Call tracking showed they were missing 70% of incoming calls — roughly 15 calls per day went unanswered.
This is not unusual for the industry. The U.S. Bureau of Labor Statistics reports there are roughly 490,000 plumbers in the U.S. with median establishment size of 5-9 employees, the same crew size as this case. With most of the team on-site, missed inbound calls are the default state, not the exception.
The Setup
Total setup time: 12 minutes. The owner entered his website URL, the scraper pulled services (drain cleaning, water heater repair, repiping, emergency service) and hours. He added pricing ranges and his service area (25-mile radius from downtown). Deployed to both the website widget and a new SMS number.
90-Day Results
| Metric | Before | After | Change |
|---|---|---|---|
| Call answer rate | 30% | 100% | +233% |
| Leads captured/week | 6 | 14 | +133% |
| Estimates booked/week | 4 | 12 | +200% |
| Google reviews | 23 | 52 | +126% |
| Monthly revenue from new leads | $8,000 | $12,000 | +$4,000 |
The ROI
$4,000/month in additional revenue against a $149/month Growth plan. That is a 27x return on investment. The owner's only regret: "I should have done this a year ago."
