Johnstone Supply

Johnstone Supply isn't a home-repair crew — it's the Braintree warehouse contractors call when they need the parts and equipment to do the job. The branch at 50 Rocsam Park Road, part of the Johnstone Supply Parker Global Group, opened in 2022 with a 4,000-square-foot showroom and one of the group's largest distribution warehouses in New England, stocking furnaces, mini-splits, and the installation accessories that go with them. On Google it holds a 4.3-star average from 13 ratings, and a directory summary claims four of four detailed reviewers gave it 5 stars for competitive pricing. That doesn't fully square with the one detailed account on file this year: a June 2026 review describing calls answered with an immediate "please hold" and no greeting, then a 20-to-30-minute wait before anyone came back on the line. Whether that's a one-off or a pattern is hard to tell from so few detailed reviews — worth asking directly about typical hold times or planning a will-call pickup rather than trying to get through cold. For contractors sourcing HVACR equipment on the South Shore, it's a well-stocked option with a pricing edge on paper — just budget some patience for the phone.
