Complete Mechanical Services is a Malden, Massachusetts HVAC company under a background-checked owner, about seven years in business, offering residential heating and cooling, duct work, and plumbing-adjacent jobs like water heaters. In a January 2026 review, a customer described a water heater that sprang a leak, and the crew came out the same day and got it replaced, calling the work professional and prompt. Another January 2026 review praised the install work and technical skill, noting the team worked after hours to finish the job right. Both reviews on Thumbtack rate the company five stars. For a heating, cooling, or water-heater job in the Malden area, this looks like a solid call for someone who wants a same-day response; ask about pricing and warranty coverage for the specific job before booking.
