    Michael Amore

    M&M Precision Plumbing And Heating Corp. is a great business and a valuable resource to the community. At the recommendation of a master plumber who does not service my area, I initially retained M&M to perform routine maintenance of my gas boiler, which Russ handled expertly. But a couple of weeks later, the main water line from the curb stop to my house sprung a leak and required complete replacement. This is a major job that can take weeks. M&M had the job done and water restored to my house within days of my acceptance of M&M’s estimate. Everyone at M&M is a pleasure to work with. Owner Max is totally involved, highly accessible, and is deeply committed to maximum customer service. The firm even uses an AI tool that is virtually impossible to tell from the real thing, ensuring 24-hour interactive service. Judy, who runs the office is an absolute pleasure to work with. Knowledgeable and caring. Can’t go wrong with this great plumbing concern.

    Just used M&M Precision to replace my old boiler and hot water heater and I could not recommend them enough. From start to finish, the experience was excellent. They are extremely thorough, quick, knowledgeable and left everything spotless when the job was done. Everything was explained very clearly and they made the entire process stress-free. Very professional and trustworthy. If you’re in need of a boiler replacement, look no further.

    Max and his team were simply phenomenal. He was very communicative, professional, and did a wonderful job with our boiler. He walked us through all of our options, presented and explained all the problems very thoroughly, and helped us come to the best resolution. He has a wonderful office staff who always go above and beyond for their customers. I would recommend Max to anyone looking for any hvac or plumbing services. He’s trustworthy, honest and his prices were great compared to local companies. Couldn’t have been happier with our decision to use his team and will continue to recommend them going forward. Absolute best in the business and so glad they’re local!

    As a homeowner, it is very hard for me to trust plumbers because they come up with random numbers, excuses and reasons to increase your quote. However, I trust this company with all my heart, and I do not hesitate in calling them when I need them for a job. No longer do I call 3 different plumbers from 3 different companies to seek a quote. This company is my go to because of their honesty when it comes to the job and their transparency. The workers are ALWAYS excellent when delivering customer service, and are never rude when I have questions or concerns. Thank you Joe Gallapoli for the recent job he did at my house and for explaining the issue with patience and understanding. If you are just like me who is uneasy about other companies, give M&M Heating and Plumbing Corp a try.

    Max and his associate just finished our 3-part boiler repair. He could not have been more polite, efficient and professional. Max answered all my questions about the job, and thoroughly explained our options for the fix. Happy to say thanks to Max at M&M, we now have hot water again. We just recommended him to a friend in town, and he promptly paid her a call to diagnose the issue. If you need dedicated, communicative and experienced HVAC tech, search no further than M&M and crew.
