"Mouradian Plumbing and Heating were instrumental in our renovation, and I can’t say enough good things about them. We were in the process of purchasing a home and had a complex situation — we needed to replace a failed forced hot water radiator system with an entirely new heating system. It was a major decision, and from the initial inquiry, Eric was someone you immediately feel comfortable working with. He’s knowledgeable, patient, and transparent — and he genuinely wants the outcome to be right for the homeowner. He guided us through the decision-making process, solved problems calmly, and made sure everything was done correctly. He is truly the reason we were able to move forward with purchasing our home. His team is outstanding. They installed a complete Bosch heat pump system with gas backup, ran all new ductwork, and supported our kitchen and bathroom remodel, including the installation of a new Rinnai tankless water heater. They did a fantastic job. "

"Danny, from HL Bowman, quickly understood the scope of the installation and used his expertise to make the installation seamless. As a result, the filtration system he installed is now operating perfectly to remove particulates greater the 5 microns from our well water. I would highly recommend HL Bowman for your plumbing needs. "

"We have been loyal customers of Genove for years, but this year they exceeded any expectations. From the emergency service call on a cold Sunday night in February to the installation of the new furnace and hot water heater today. Armando and crew are terrific. Ryan, Richie and Shawn completed the project in less time than we expected. And, Armando assisted us in the HEAT loan program which has us paying for this work at zero interest over 7 years as well as handled the rebate programs. Highly recommend Genove!"

"My grandson flushed his little yellow bus down the toilet Friday afternoon. I called several plumbers in the area. By late Saturday afternoon I had only 1 returned call saying they could come out Monday morning. A friend suggested I call Gentille Plumbing and Heating. I called them and they said they could come early Sunday morning. Ryan arrived promptly as promise and quickly determine how to approach the issue and retrieved the little yellow bus. Cleanup was quick and pricing fair. Ryan was professional , friendly and was on his way within 45 minutes of arrival. Thank You Gentille Plumbing and Heating"

"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!!"
