Best of all, these guys know the systems
I had an aging combi boiler that was starting to have issues. I'd spoken to a few service providers and gotten mixed advice on whether to repair or replace my unit, and wildly different diagnoses of the problem(s). I stumbled onto a YouTube video of DiBacco Plumbing repairing my exact model boiler and decided to give them a call. I am so glad I did! Ralph answered the phone immediately, and as I began describing my situation, he identified the issues I was seeing, described them to a T, and gave me a detailed description of the root cause of the problem. He laid out a few different repair and replacement options and gave me a clear list of pros and cons to each. He asked if I could send in photos of my system and was able to give me a (very reasonable) quote for a replacement the same day. Mike and Cody were on-site two business days later and completed the install without issue. They were clean, efficient, and professional. Best of all, these guys know the systems they install inside and out. It's fantastic to find a local family-owned business that is easy to work with, quick, does an excellent job, and charges a fair price. If you're looking for a boiler repair or replacement, look no further!

Amazing Team During Cold Snap
During an intense winter cold snap, our furnace/boiler failed. Ralph, his son, and their team were amazing. They responded to our distress call on a Sunday, created a temporary fix for the existing boiler, quickly developed a reasonably priced permanent replacement, and returned the next week to install a new tankless hot water heater. They were prompt, efficient, worked independently, and cleaned up after themselves. I’m pleased to recommend DiBacco Plumbing and would gladly use them again.

Excellent Integrity
Ralph just finished installing a complete boiler room setup for me: condensing boiler, 5 zones, 5 pumps, 5 mixing valves - he brought the boiler and zone piping prefabbed on a 4'x8' backer board - installed, and then spent time hooking up to both radiators and radiant floor manifolds I had installed in my house - very knowledgeable, good understanding, good communication, and above all, excellent integrity. I'm very happy I decided to hire him - he'll be my first call for my future plumbing/heating needs - Thanks, Ralph!

Wonderful Job by Ralph and His Team
Ralph and his team installed a new boiler and tankless hot water heater at our recently purchased home, and they did a wonderful job! Ralph was easy to communicate with, showed up on time, explained everything to me that was done, and left the place cleaner than when they got there! Couldn’t recommend them enough. We are so happy to go into our first winter in our home confident in our heat!

They are my heroes.
I can't say enough great things about owner Ralph DiBacco and his DiBacco Plumbing and Heating team. They proved to be experts in the repair and installation of Navien Combination Boiler/Tankless Water Heating Systems. Quite simply, they are pros who know their stuff. Add in the fact that they went above and beyond and bailed me out of a no-heat, no hot water situation on a Friday afternoon before Memorial Day Weekend, and they are my heroes. Many thanks to DiBacco Plumbing and Heating for a job well done.

Exceptional Forethought and Knowledge
DiBacco Plumbing revised our zone heating efficiently and provided expert knowledge to reprogram our boiler. Phil approached the project with exceptional forethought and had more knowledge of how to make our condensing boiler heating system perform properly. He shared his knowledge and explained the system better than any plumber we have used. This was a complex job to split a zone, add new valves, and install new thermostats in our 140-year-old home. We had one small issue due to plumbing hidden in a wall, and Phil and team were here the next day to resolve the unforeseen problem. Excellent work, and I highly recommend them.
