What Thornton & Grooms does

Thornton & Grooms is a privately held, 87-year-old (founded 1937) residential home services contractor headquartered in Farmington Hills, Michigan, employing 251–500 people and operating exclusively across 19 communities in Southeast Michigan (Oakland, Wayne, and Washtenaw counties). The company delivers a full-stack home services portfolio spanning HVAC (furnace, heat pump, boiler, A/C repair/installation/maintenance), plumbing (water heaters, frozen/pipe leak repair, sump pumps, gas lines, water quality), drain and sewer (unclogging, CIPP trenchless lining, hydro jetting, camera inspection, replacement), electrical (panel, whole-home rewiring, surge protection), and indoor air quality (air purifiers, humidifiers, dehumidifiers), with smart thermostat installations as an add-on. Differentiated technical capabilities include trenchless drain repair (pipe lining/patching, hydro jetting), free residential drain/sewer camera inspection, and Lennox Premier Dealer–level factory training for HVAC and air quality equipment.

The business operates a direct-to-consumer, field-service model: customers schedule via phone ((248) 644-7810) or an online portal, and licensed, NATE-certified technicians visit homes—offering same-day service during business hours with a 'We Care Guarantee.' Thornton & Grooms generates revenue through (a) transactional service and repair fees (e.g., $99 drain unclog, $99 electrical troubleshooting, $400+ water heater repair, $99 plumbing safety inspection), (b) installation projects (e.g., $2,300+ water heater installation, $500–$30,000 drain/sewer work, $2,500–$7,500 whole-home rewiring), (c) a recurring Home Care Club membership at $20/month that has scaled to 10,000+ members and provides priority service and discounts, and (d) parts and equipment sales. Strategic OEM relationships with Lennox and Insinkerator anchor preferred-dealer economics, and customer trust is reinforced by a 4.9 average rating across 16,094 Google reviews, BBB A+ accreditation, and a Detroit Free Press 'Best HVAC Service Company' recognition.

In 2025, Thornton & Grooms acquired/rebranded Burton & Sons in Garden City, extending the company's footprint into Wayne County. The company remains privately held with no disclosed institutional ownership, no funding rounds, and no parent company.
