"Eric Mouradian (owner) responded promptly to my request for urgent replacement of a newly-broken hot water heater. He showed up on time, provided outstanding service, cleaned up after the job, and charged a reasonable price. Highly recommended!!"

"We were very pleased with the work that the Genove technicians did. They removed our 40-year-old gas boiler and associated water heater and replaced it with a new system. They tested the new system carefully, put explanatory tags on all of the relevant pipes and faucets, and cleaned up well. The team members were polite and worked hard. We had similarly good experiences when Genove technicians came to repair our central AC system. They were knowledgeable and efficient, got the system going again, and the price was fair. We continue to use this company for heating and AC repairs."

"Justin and Cam, the technicians, did a great job. We have an old farmhouse with a very strange configuration of partial crawlspace and partial full basement, and water was leaking through the fieldstone foundation wall from the crawlspace. They quickly diagnosed that the problem was coming from 1 or 2 zones of the hot water radiator heating system, and they were able to shut off those zones to stop the leak, while allowing the house to still use water for sinks, toilets, and showers. We'll have to do more work later to replace pipes to the radiator but, because they are hard to access, we need to plan ahead for some construction work. I'm fully satisfied that these guys were able to find the problem and give us even a temporary solution that allows us to have our working plumbing again without the basement getting wet. Would definitely work with them again."

"So glad I had a chance to work with O?Brien Plumbing works! I had a scary water heater leak on the night before the night before Christmas - Max O?Brien responded to the Angi post first, and arrived quickly, fixed the leak expertly, and also showed me around the system so I better understand my furnace. Plus he cleaned everything up when finished. He was polite, knowledgeable, and expedient. Thank you O?Brien Plumbing Works!"

"Brian and his crew were great. Brian came out and gave a great estimate for everything I needed. He was very responsive via email as we worked to schedule a time for his crew to come do the work, which was mainly water tank and heating system maintenance. Brian brought Jim promptly and explained the work. They then pointed out a couple of things that they recommended replacing, one they just included in the original cost estimate and another they added on due to additional parts being purchased. Jim was very thorough and professional and, by all accounts, did great work. I’ll be using Heavy Doody for all of my future plumbing and heating needs!"

"John is hands down the best plumber I?ve dealt with. I had a frozen pipe and after calling multiple plumbers who couldn?t identify the issue or offered zero real help, John came through immediately. He showed up the same day I called, quickly found the problem, and had everything fixed within 30 minutes. He was knowledgeable, efficient, and clearly knew exactly what he was doing. After a stressful situation and a lot of wasted time with other companies, John made the whole process easy and painless. I wouldn?t hesitate to call him again and will be recommending him to everyone I know."

"The technician and electrician were both very respectful, knowledgeable, provided all options, were open and honest about why they recommend the service chosen, helped in obtaining the financial services, walked me through the entire process. The technician went above and beyond making sure the. After the water heater install was completed he performed a safety inspection on my heating system, cleaned the debris from the flute into the chimney, made a few tweaks here and there to make sure my system was performed to his satisfaction. I was extremely appreciative of his care, concern and professionalism."

"I would highly recommend Damaso Plumbing. My water heater was leaking and had let go. I called Brian at 7 am and they were here at my house at 8:15 am with a brand new gas water heater. He was very professional and they were extremely neat with the job. He had given me an estimate over the phone and charged me exactly what he quoted which I really appreciated. Great Job!"
