Call Maffei on a bad plumbing morning and, more often than not, someone shows up the same day — that response speed is the thing reviewers keep coming back to, alongside an A+ Better Business Bureau accreditation the company has held since 2016. Based in Rowley, the crew handles everyday plumbing and HVAC work — water heaters, drain clogs, mini-split maintenance, boiler repairs — and its 4.7-star average holds steady across Google's 898 ratings and its smaller HomeAdvisor and Angi counts. The reviews that repeat aren't about one lucky call. Anton(io) Ferreira comes up by name across several recent reviews for patient, thorough diagnostic work, including a decades-old backflow pipe repair and a leak one customer says other companies couldn't resolve. Ryan, Joey, Tony, Kyle and DJ each get their own shout-outs for walking customers through the problem before starting, and a recent HVAC and mini-split maintenance visit is described with the technicians photographing the inspection and explaining what needed attention now versus later. The recurring complaint is price, and it comes up often enough across the years to be worth asking about upfront. One recent review describes a $400 charge for a roughly $15 valve swap that took about half an hour, and a late-2025 review says a customer paid $624 to replace a $25 sink strainer. A 2025 review reported a bid on a boiler job that came in more than five times a competing quote, and a 2022 review described a similar pattern — a $581 charge for a faucet install using the customer's own parts, an unhonored coupon, and a repair that leaked afterward. A separate 2025 review said a routine water-heater maintenance visit skipped the diagnostic checks the customer expected. Maffei looks like a solid call for a same-day plumbing or HVAC problem where speed and a technician who explains the fix matter — just get the price in writing before anything beyond a small job gets started.
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.
