First Class Plumbing

First Class Plumbing & Heating is a Quincy business that says it has served the Greater Boston area and South Shore since 1998, run by President David DiBona. Its Massachusetts plumber license is registry-verified active, and the company has been a BBB-accredited A+ business since 2003. The written record here is thin — just two reviews, both from the past year and a half — but detailed. A January 2026 review described a leaking exterior pipe fixed the same day it was reported, with the pricing explained before the work started. An April 2025 review described a new heating system installed with a clear walkthrough of how to use it, followed by annual servicing in the years since. One additional signal stands out: a web mention described the company as one of the few able to work on Baxi Luna boiler systems, with David walking a customer through testing and troubleshooting three separate units after a long search for anyone who knew the equipment. That lines up with the company's own listed Baxi Certified Technician credential, alongside OSHA 10-hour and NFPA Hot Work certifications. With only two written reviews, this isn't a deep history, but what's on file points to a long-established, licensed operation with real technical specialization in less common heating equipment. Anyone with a Baxi boiler or a routine plumbing or heating need in the Quincy area is who this points to being served well.
