# Riggs Plumbing HVAC **Trade:** HVAC / Heating & Cooling · **Website:** https://www.riggsplumbinghvac.com/ · **Languages:** English **Rating: not yet scored** — 0 reviews across 4 sources is too little evidence for an honest number. ## The honest read Riggs Plumbing HVAC (also doing business as Riggs Mechanical, Riggs Plumbing & Heating, and Riggs Plumbing, Heating & HVAC) is a Weymouth-based, family-owned plumbing and HVAC contractor serving the South Shore and Greater Boston -- boilers, furnaces, heat pumps, mini-splits, water heaters and plumbing fixture work, per its BBB profile and website. BBB records it as a sole proprietorship with one employee, owned by Robert Riggs, accredited since 2012 with an A+ grade. How long the company has actually been operating is unclear: BBB dates its start to January 2010 (about 16 years), its own website claims 20 years in business, and its Angi profile -- which shows no reviews yet on either Angi or HomeAdvisor -- lists 8 years of experience. The three don't agree, and it's worth asking directly. The company's Master Plumbing, Journeyman Plumbing and Process Piping license numbers appear on its own website but haven't been verified against the state registry. With no customer reviews on file anywhere yet, there's nothing here to weigh the work against -- worth asking for references before booking. **Where sources disagree:** - Its BBB profile dates the company's founding to 2010 (about 16 years in business), its website claims 20 years in business, and its Angi profile lists 8 years of experience — the three sources disagree. ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. -
