Aya Cl says, "As a Needham homeowner, I value contractors who show up when promised and treat the house with respect. Green Energy checked both boxes for me. The technician explained my options clearly and gave a written estimate before starting. The work itself looked tidy, and they tested everything, checked for leaks, and cleaned up. I also appreciated that they took time to answer a few extra questions that werent strictly part of the job. Scheduling was straightforward and the office was responsive.Pricing felt on the higher side for certain items, so its worth asking for a detailed breakdown and alternatives. That said, I never felt pushed toward an unnecessary replacement. On one visit a part wasnt on the truck, which meant a second trip, but they were upfront about it and communicated the plan. Since the service, my system has been running as it should, and they flagged what to watch for next season.I like that they handle both heating and plumbing, which keeps things simple for future maintenance. Professional, courteous techs and solid follow-through overall. Verdict: dependable service with room to improve on pricing transparency and parts readiness; 4/5 and Id use them again for routine work."See more

Scale can build up inside a tankless unit even when hot water still seems normal, so maintenance is easy to put off. A technician can often spot early mineral buildup that reduces efficiency, which may help preserve flow and avoid a harder flush later.

Stanley Staco says, "I contacted Addario's Plumbing, Heating, Cooling & Electrical Services on a Sunday evening through social media after a newly installed indirect water heater left us without hot water. I was impressed by how responsive they were and was able to schedule a Monday morning appointment. The technicians arrived within the promised time window.Unfortunately, the first technician crew sent were overwhelmed by the issue. After taking photos he repeatedly presented authorization forms and charges before even explaining the problem or proposed solution if any would even be viable. Despite being informed that an electrician had already verified the wiring, he kept suggesting and pushing that the issue is electrical and he clearly uncertain about the next steps.To Addario's credit, once the situation was escalated, a supervisor quickly recognized that a different skill set was needed and reassigned the job to another team. The replacement technicians were outstandingprofessional, knowledgeable, transparent, and thorough. They quickly diagnosed the issue, clearly explained the repairs and costs, and worked diligently for several hours to restore our hot water. They also took the time to explain follow-up recommendations to prevent future problems.The final cost was close to $900, which is significant, but given the emergency nature of being without hot water, I needed the issue resolved quickly. In the end, the second team earned this review and turned what was becoming a frustrating experience into a positive outcome."See more

Zack Karantonakis says, "I recently had CleanTap Water Solutions out to my home in Mansfield and couldnt be happier with the experience. From the first call to the finished job, everything was smooth and professional. They responded quickly, showed up on time, and really knew their stuff.We had a mix of plumbing issues and were also looking into improving our water quality, and they handled both perfectly. They explained our water filtration options in a way that actually made sense and didnt try to upsell anything unnecessary. You can tell they genuinely care about doing the job right.Its hard to find reliable contractors around here, but these guys are the real deal. If youre anywhere in the Mansfield/Foxboro area and need plumbing work or water filtration, Id definitely recommend giving them a call."See more
