Rob Roy Mechanical

Rob Roy Mechanical is a Londonderry plumbing and heating-and-cooling contractor operating from 86 Nashua Road. New Hampshire's license registry lists the company's MBE1901170 plumber license as active, and BBB lists the same license number, an A+ grade, and plumbing-and-heating and HVAC services. The company's website currently confirms its address and phone but is still under construction, so the clearest description of its work comes from the license, BBB listing, and customer accounts. The customer history is substantial: Google lists 4.9 stars from 259 ratings, while 146 written reviews on file span 2021 through 2026. Recent reviewers describe fast help with air-conditioning, heating, water-heater, well-pump, and plumbing problems. More detailed accounts describe technicians diagnosing an AC failure, repairing a long-running leak, replacing a furnace over two days, responding after hours to a gas leak, and leaving work areas clean. Prompt scheduling, clear explanations, courteous technicians, and careful cleanup recur across the positive reports. There are concrete reasons to discuss pricing and diagnosis before authorizing work. A 2023 one-star review said a toilet-tank repair cost more than $430 at a stated $230 hourly rate and criticized time rounding. Another 2023 account described a three-hour arrival delay, charges for two workers, additional valve work, and an unfinished appliance reconnection. In a 2022 three-star review, a customer said a technician replaced the customer's fuse but did not identify why the heat-pump fuse had blown. These are older accounts, but they support asking for the hourly rate, minimum charges, staffing, scope changes, and diagnostic plan in writing. Rob Roy Mechanical is best matched to homeowners seeking licensed plumbing or HVAC service in and around Londonderry, especially for boilers, furnaces, air conditioning, water heaters, leaks, and gas piping. Before booking, confirm the service-call fee, after-hours rate, number of technicians billed, and what follow-up is included when troubleshooting an intermittent problem.
