First Class Plumbing

First Class Plumbing & Heating is a Quincy shop that's been running since 1998 — the company says nearly three decades in business — led by President David A. DiBona, described on its site as hands-on and having started the company out of a wish to help people. It covers plumbing, heating, and cooling work across Quincy, Greater Boston, and the South Shore. The written record is short but consistently positive. In a January 2026 review, a homeowner said the company fixed a leaking exterior pipe the same day it was called and walked through the pricing before starting. In a 2025 review, another described a full heating system install where the crew explained how to operate the new equipment and has returned for a service visit every year since — three years in with no issues reported. Separately, an undated mention on a French-language directory site credits the company, and specifically a technician named David, with troubleshooting a hard-to-service Baxi Luna boiler setup — which lines up with the company's own listed Baxi-certified-technician credential. Its Massachusetts plumbing license is active, and it carries a BBB A+ rating with accreditation dating back to 2003. Only two customer reviews are on file despite the company's long run, so there isn't much of a written track record to weigh beyond these two accounts and the Baxi mention. For a straightforward repair or a full heating-system install in the Quincy/South Shore area, this reads as a small, established operation with a specific niche in Baxi boiler equipment — worth asking about directly if that's the system in the house.
