Total Mechanical Systems

What Total Mechanical Systems does

Total Mechanical Systems, operating under the DBA "TMS Comfort," is a privately held residential home services company founded in 2001 and headquartered at 74 Northwest Drive in Plainville, Connecticut. The company serves Connecticut homeowners through a direct-to-consumer model across four integrated service lines: HVAC (air conditioning, furnaces, boilers, heat pumps, ductless mini-splits, and oil-to-gas conversions), plumbing (water heaters, leak detection, water treatment, sewer line services), drains (cleaning, hydro jetting, sewer camera inspection, and trenchless CIPP pipe lining), and electrical (panel upgrades, generator installation, EV charging, and surge protection). Indoor air quality assessments and whole-home safety checks round out the offering. Service is delivered by NATE-certified HVAC technicians and licensed plumbers and electricians, with 24/7 emergency availability and same-day response enabled by the centrally located Plainville facility.

The company's revenue mechanics rest on four streams: installation services (HVAC systems, water heaters, electrical panels, generators, EV chargers), repair and maintenance services (transactional service calls), equipment and parts sales bundled with installations, and the Comfort Shield annual membership program, which generates recurring subscription revenue through twice-yearly maintenance visits, extended parts-and-labor warranties, $100 annual HVAC purchase credits (up to $1,000 total), a 15% repair discount, and whole-home safety checks. Pricing is primarily quote-based, with example disclosed figures including a $128.30/month financed price for a $14,257.78 AC system over 180 months at 6.99% APR via Service Finance Company, an $89 sewer camera evaluation, and a $149 electrical panel inspection. Distribution combines in-house phone/web scheduling with a Home Depot Home Services referral channel and co-marketing rebate alliances with EnergizeCT and Connecticut utilities (Yankee Gas, CL&P, Connecticut Natural Gas Corporation, United Illuminating).

The business is operated as an independent LLC with no disclosed parent company, external equity investment, or M&A activity, and equipment installations rely on partnerships with major HVAC brands including Daikin, Trane, Lochinvar, Thermo Pride, and Weil-McLain. The company has accumulated a brand asset base built on more than two decades of operating history, BBB A+ accreditation, and hundreds of 5-star reviews across Google, Facebook, and Yelp. No management team, headcount, revenue, or funding data is publicly disclosed, and the company shows no app, API, or AI/ML capability surface in the available information.
