Introduction
Harbor Plumbing is a six-person residential plumbing company operating in the Pacific Northwest. Before they switched to Letsdial, they were running on a standard carrier line with a basic voicemail box. Sarah Ellis, the owner, estimates they were losing two to four jobs per week to after-hours missed calls — customers who left a voicemail, didn't hear back within an hour, and booked a competitor instead.
The problem with voicemail in home services
Home services customers don't wait. A pipe is leaking or a drain is backing up, and the first plumber who responds gets the job. Voicemail is a 12-hour lag in an industry where the booking window is often 20 minutes. 'We were first call, last callback' was how Sarah described it. They had strong word-of-mouth and a high first-call rate. They just weren't capturing it.
“I'd come in on Monday morning and there'd be eight voicemails, six of which had already booked someone else. We knew the calls were coming in. We just couldn't answer them.”
Week one with the AI receptionist
Harbor Plumbing went live with the Letsdial AI receptionist on a Tuesday. The setup took about 40 minutes: Sarah recorded the business name and service area, defined the questions the AI should ask (nature of the problem, urgency, address, preferred callback time), and connected her existing plumbing scheduling software via the Letsdial integration.
By Friday of that week, the AI had handled 11 after-hours calls. Of those, 8 were booked directly into the schedule. Two were non-emergency inquiries that were logged for a Monday callback. One was a wrong number. None went to voicemail.
What changed operationally
The most significant operational change wasn't the booking volume — it was the quality of the intake information. Before the AI, voicemails were often incomplete: a name, a vague description of the problem, and a callback number that might or might not still be answered. The AI collected a structured intake form on every call: address, problem description, urgency, preferred time, and a confirmation of the callback number. When a tech showed up on a job, they already knew what they were walking into.
- 8 of 11 after-hours calls booked in week one
- Average intake completeness went from roughly 40% to 100%
- Monday morning voicemail reviews dropped from 30+ minutes to zero
- Techs arrived on jobs with full problem context for the first time
Three months in
At the three-month mark, Sarah estimates the AI receptionist is responsible for roughly $14,000 in additional monthly revenue — jobs that previously fell through the after-hours gap. The company has also changed how it thinks about staffing: instead of scheduling a rotating on-call line for evenings and weekends, the AI handles all intake and only escalates genuine emergencies that need an immediate dispatch. The on-call rotation still exists for dispatch, but it's shorter and less frequent.
“It paid for itself in the first week. I'm not exaggerating — the first week. Now I can't imagine running without it.”
