AI for a 135-person remodeler: a custom Claude business advisor and scope-of-work reviewer at Mosby Building Arts
Mosby Building Arts
Mark McClanahan, president of Mosby Building Arts, a 135-person remodeling company, describes in a Pro Remodeler article how the company adopted AI. All 12 of its managers use a "Mosby Business Advisor," a custom Claude project built from a 30-page operating-system prompt plus seven files covering core values, strategy, financials, target market, the employee manual and management team profiles, which he says took about 70 hours to build. A custom AI scope-of-work reviewer checks each of its 13 salespeople's scopes for grammar problems, inconsistencies and conflicting information before they go to the client, and a handoff tool to standardize scopes passed from eight designers to two estimators is on the roadmap. McClanahan says a monthly employee newsletter article went from 45-60 minutes to about five. He puts subscriptions at roughly $450 a month and says staff must read and own anything AI writes. Figures are his own, from a first-person trade-magazine article.
AI for a plumbing and HVAC shop: Claude CSR onboarding plan, QuickBooks analysis and AI after-hours calls
BWS Plumbing, Heating & Air Conditioning
Kevin Strandberg, owner of BWS Plumbing, Heating & Air Conditioning in Eden Prairie, Minnesota, describes on the Plumbing & HVAC Hustle Podcast how he uses Claude. He says he had it write a two-week, day-by-day onboarding plan for a new CSR with no HVAC or plumbing background, with supporting documents and daily tests, in about 30 minutes. He connected Claude to QuickBooks Online and asked for an in-depth analysis of first-quarter financials, getting an executive summary he could take into an accounting meeting, and had it draft a month-end close process for their ServiceTitan, ADP and QuickBooks setup. He also uses it for HTML email blasts and reports that BWS runs an AI phone agent from Avoca for after-hours calls, which he says works well on the second try after a vendor switch and fine-tuning, but that customers still want humans in business hours. His cautions: it still hallucinates, so he checks the output, works in batches of three to five tasks, and fixed a pricing error that Claude now remembers. No numbers beyond the 30-minute onboarding plan are given; this is the owner's own account on a podcast hosted by a marketing agency.
AI for a solar installer: an AI lead agent plus Claude on live CRM and ad data took installs from 4 to 48 a month
Green Subsidy
Green Subsidy, a solar and battery installer in Australia, had about four installs a month, an ad account that had sat idle for two years, and online inquiries that waited on a human. According to partner SkySync's customer story, inbound leads from Meta, Google and the website now go to an AI agent on WhatsApp and Messenger that qualifies the lead, checks rebate eligibility, builds the quote and books the assessment and install into the crew calendar, with everything written to Salesforce. SkySync also connected Salesforce, Meta Ads and Google Ads to Claude so the CEO can ask which campaigns produced paying customers instead of exporting three systems into a spreadsheet. SkySync reports installs went from 4 to 48 a month, lead response is under two minutes, and A$8,984 in ad spend produced 518 leads and 103 customers (about A$87 each) worth A$2.15M in system value. Its 239x gross return figure includes the Australian government rebate; on customer cash alone it says 98x. In production since February 2026 and operated by SkySync; vendor-published figures, not independently audited.
AI for plumbing and HVAC back office: Claude-built pricing calculators, payroll workbooks and automatic install jobs
Blanton & Sons (Adam Grubb, GM; Charleston, SC area)
Blanton & Sons, a family-owned plumbing and HVAC company in the Charleston, South Carolina area, runs on ServiceTitan, and general manager Adam Grubb (a former plumber) automates every back-office process he can. He used Claude and ChatGPT to build his own tools: a mobile pricing calculator where a tech enters equipment cost, material cost, target margin and commission and gets a price plus a range of acceptable prices, a reverse version that shows management the margin and commission a quoted price implies, and payroll workbooks that handle South Carolina's overtime-on-commission math. With an outside AI shop he built a workflow that takes a job a tech marks "perform later," builds the install job in ServiceTitan and sends the purchase order, which replaced the install coordinator's paperwork; that employee now spot-checks the automation and spends her time with customers. Techs use ServiceTitan's Atlas assistant and ChatGPT for troubleshooting and manuals, and a vendor tool called Buck AI assigns calls on the dispatch board by tech skills, area and schedule. Grubb says dispatch "used to be an all-day job" and is now weekly capacity management. He outsources anything with legal exposure, such as payroll automation. No figures beyond his own descriptions.
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.
AI back office for remodelers: connect Claude to JobTread for proposals, vendor bills and job-close audits
Element Design Build
Element Design Build, an eight-person design-build remodeler in Hudson, Ohio, uses Anthropic's Claude as the link between its existing software: JobTread for project management and job costing, Fireflies for call transcripts, and Microsoft 365. Owner Vlatko Demrovski records prospect calls and consultations with Fireflies, then has Claude summarize them and help prepare JobTread proposals from templates and historical job costs; he says proposals that took 60 to 90 minutes now take 10 to 15, and a $150,000 kitchen estimate that took two days often takes about three hours. On the accounting side, an AI agent helps input vendor bills, match purchase orders and budget line items, and support reconciliation; job-close audits now happen on every job, and commission calculations that took a full day are done in under an hour with an audit trail. Claude also drafts schedules from the company's actual task durations. Element grew from $3.74 million (2024) to $3.92 million (2025) with the same headcount, which Demrovski largely credits to this setup. He reviews every output ("I read every single word") and tests spreadsheet instructions on one row first. Figures are owner-reported in Qualified Remodeler's 2026 Fred Case Award profile.
