Mr. Plumber by Metzler & Hallam

What Mr. Plumber by Metzler & Hallam does

Mr. Plumber by Metzler & Hallam is a residential plumbing and HVAC service provider operating exclusively in Central Indiana since 1946. The company is a wholly owned subsidiary of Wrench Group, LLC (a multi-brand home services holding company headquartered in Sarasota, Florida), and operates alongside sister brand Williams Comfort Air under the MAX Service Group umbrella, which also encompasses Thomas & Galbraith, Buckeye Heating & Cooling, and Jarboe's. Mr. Plumber serves homeowners across seven physical office locations — Indianapolis (HQ), Carmel, Broad Ripple, Noblesville, Greenwood, Fishers, and Plainfield — with a 24/7 emergency response capability including holidays, and claims 235,225+ cumulative homes served, 19,624+ True Comfort Membership subscribers, and a 4.9-star Google Business rating across 25,995+ reviews.

The company's service portfolio spans emergency plumbing repair, water heater installation and replacement (tanked and tankless), drain clearing, sewer line repair and replacement (including trenchless pipe bursting), sump pump installation, water quality solutions (softeners, filtration, analysis), whole-home repiping, and HVAC services delivered under the broader MAX Service Group umbrella. Its technology stack is service-delivery oriented rather than software-platform oriented, with notable offerings including Wi-Fi-connected water leak and freeze detection systems, a content-heavy website (88+ knowledge center articles), and background-checked, EPA- and NATE-certified technicians completing 12,367+ annual training hours. The company holds Indiana plumbing license CO50800249 and electrical license EL2300041.

Revenue is generated through four streams: on-demand professional service calls (per-job pricing with upfront quotes), equipment sales and installation (Bradford White, EcoWater, Carrier, Navien brands with financing from $22–$25/month), recurring True Comfort Membership subscriptions ($9 plumbing / $18 HVAC / $24 combined monthly tiers), and a customer referral program paying $25–$125 per referral. The go-to-market is direct-to-consumer only, with no third-party distribution; acquisition channels include 24/7 phone dispatch, online scheduling, organic SEO and Google Business profile, multi-platform social media, sports team sponsorships (Indy Eleven, Indianapolis Indians, Indy Ignite, Symphony on the Prairie), a charitable giving program (MAX Gives), and an active digital coupon book.
