AI automation for plumbing and HVAC: have Claude build workflows that catch every lead and feed Google Ads real jobs
3R Plumbing & Mechanical
3R Plumbing & Mechanical, a veteran-owned residential plumbing and HVAC company in Norwell, Massachusetts, went from about $300,000 a year when Ross Hunt started it in his garage in 2022 to a projected $3.8 million this year with 15 employees. Hunt, a Master Plumber who says he's "not a computer person," describes the workflow he wants to Claude, which is connected to Zapier through Zapier MCP; Claude writes and publishes the automation and he reviews and tests it. ServiceTitan stays the system of record. Since late August 2026 he has put 36 of Zapier's AI-built Next-Gen Zaps live, running about 1,400 times a week. They email him when a booking from 3R's AI answering service, a lead marketplace or the website sits pending for 20 minutes, turn Facebook landing-page leads into ServiceTitan bookings with a text and a homeowner confirmation within seconds, flag jobs tagged to the wrong ad campaign, and send Google Ads the real booked jobs and completed-job revenue each morning so ads optimize toward work that pays. A 6:30 a.m. brief gives Hunt and his operations manager the day's board, callbacks and open capacity. Revenue figures are the owner's, as reported by Zapier.
