Maffei Services is a Rowley plumbing, heating and cooling company with 4.7 stars from 898 Google ratings, an A+ from BBB and BBB accreditation since 2016. Its Massachusetts plumber licence is active. Its New Hampshire plumber and HVAC licences, held by Gregory K. Maffei Sr., are active. Recent customers describe quick, well-explained visits. A July 2026 customer called for same-day service and had Antonio there a few hours later; another that month said Shane and Yohendy took photos throughout an HVAC and mini-split maintenance visit and explained the pricing clearly. In April 2026, a customer said Anton Ferreira fixed a job several other plumbing companies could not, and in March 2026 a customer whose boiler had stopped making hot water said Ryan showed them what needed fixing and what didn't. A January 2026 reviewer said the company had been their HVAC partner for more than 10 years. Several customers have complained about price. In July 2026, one customer said a half-hour shutoff valve replacement, a part sold for under $15, cost more than $400. A March 2026 customer with no hot water was quoted over $1,000 for a sensor and ignitor and $1,300 for cleaning, paid a $390 diagnostic fee, then bought the parts for $17 and $38 and had another company install them for $250. Another March 2026 customer, a landlord, said a technician who arrived at 4pm quoted $900 to install a customer-supplied kitchen faucet or $1,050 for a company faucet, then had none on the truck that fit. A July 2026 customer was quoted more than $1,500 to snake a sewer line after a basement toilet overflow, and said another plumber found the sewage pit pump was not running only because it was plugged in loosely. A December 2025 customer said a technician, without running tests, called their Navien water heater's heat exchanger cracked and urged replacement, and that nothing turned out to be wrong. A July 2026 customer who took a half day off for a first-of-the-day appointment said no one had come by 10am.
From the woman who answered the phone to make the appointment, to the plumber who came out are 10 out of 10. I highly recommend This company 100%
So disappointed. We initially used Maffei when our water heater stopped working and they were prompt, found the issue, and repaired it at a reasonable price. So when we found a leak in bathtub, they were our first call. The dispatcher got us scheduled right away. We were told that we'd be the first appointment of the day (around 8:30am). I took a 1/2 vacation day at work so that I could be home for the plumber and to my great disappointment, no-one showed up! I called at 10am and was told by the dispatcher that the technician was finishing up another job and would be there right after. The dispatcher offered to reschedule, but it's left such a bad taste in my mouth. I had also pre-scheduled Maffei to come out next week to tune up our AC unit, but I think I'm going to cancel and find a company that is more respectful of people's time.
This company is very professional and fair. They respond and get the job done quickly. I had the technician Tony. He was great, honest and very helpful. I would definitely use them again and recommend them to my friends.
They came right away when I called. Found the issue got the part from vendor shipped and put in as soon as they received it. Anton very friendly and did a great job explaining everything to me. Will use them again for sure.
Technical Expertise & Thoroughness ⭐⭐⭐⭐⭐ Shane and Yohendy provided thorough maintenance on my HVAC and mini-split duct systems. They took photos throughout the inspection, clearly explained their findings, and walked me through what needed attention immediately versus what could wait. Tony followed up with a detailed cleaning of both units and went above and beyond by inspecting my indoor plumbing, catching potential problems before they became major issues. Communication & Transparency ⭐⭐⭐⭐⭐ I really appreciated the clear, transparent communication around pricing and recommended services. The team took the time to discuss the Maffei Maintenance Plan, outlining what it covers, the benefits, and the exact cost options without any high-pressure tactics. Customer Service & Professionalism ⭐⭐⭐⭐⭐ All three technicians—Shane, Yohendy, and Tony—were exceptionally professional, polite, and knowledgeable. They respected my home by wearing protective shoe covers (footsies) and taking care while working inside. It’s rare to find a team where every representative delivers the same high standard of service, courtesy, and expertise.
