3R Plumbing & Mechanical LLC

Headquarters: Norwell, MA · Phone: (781) 974-5239 · Website: 3rplumbingandmechanical.com

Company Overview

3R Plumbing & Mechanical LLC is a veteran-owned, locally owned and operated plumbing and HVAC company serving the South Shore of Massachusetts from its headquarters in Norwell. Founded in 2022 by U.S. Army veteran and master plumber Ross Hunt, 3R provides residential heating, cooling, and plumbing services backed by 24/7 live answering, online booking, upfront pricing, and the company’s guiding philosophy: The 3R Standard — Recruit the Best. Run It Right. Respect the Mission.

3R holds elite manufacturer credentials that few South Shore contractors carry: the company is a Mitsubishi Electric Diamond Contractor, a Navien Certified Installer, and a Mass Save Heat Pump Installer Network (HPIN) enrolled contractor. Unlike most contractors, 3R processes Mass Save rebates upfront — applied as a discount on the customer’s contract at signing, not a mail-in reimbursement the homeowner has to chase.

3R holds a 4.9-star rating on Google across its Pembroke and Norwell business listings, with 518 total customer reviews from South Shore homeowners and 460+ five-star reviews across all review platforms. The company is Google Guaranteed and a Nextdoor Neighborhood Favorite winner in 2022, 2023, and 2025.

The 3R Standard — Our Philosophy

Recruit the Best. Run It Right. Respect the Mission.

At 3R Plumbing & Mechanical, our name is our operating system. Founded by a U.S. Army veteran, we run every job the way a good unit runs a mission — and that comes down to three commitments we refuse to compromise on.

Recruit the Best. Great service starts long before the truck arrives — it starts with who’s in it. We hire licensed, background-checked professionals, train them relentlessly, and pay them like the skilled tradespeople they are. When a 3R technician walks into your home, you’re getting someone we’d trust in our own.

Run It Right. No shortcuts, no surprises, no fine print. Every call is answered live, 24/7. Every repair is diagnosed before it’s priced, and priced before it’s started. Every replacement comes with Good, Better, and Best options — and every Mass Save rebate is taken off your price at signing, not mailed to you months later. Done right the first time isn’t our goal. It’s our minimum.

Respect the Mission. The mission is your home and your family’s comfort — and we treat it that way. We respect your time by showing up when we say we will. We respect your house by leaving it cleaner than we found it. We respect your budget by telling you the truth, even when the truth is “you don’t need to replace it yet.” Complete the mission, take care of people. That’s how our founder was trained, and it’s how this company runs.

When we recruit the best, run it right, and respect the mission — the customer wins, the team wins, and the company earns the right to keep serving the South Shore.

Furnace Repair and Installation: Gas furnace diagnostics, repair, and replacement, including Bosch and Trane equipment.

Ductless Mini-Split Systems: Mitsubishi and Fujitsu ductless installation and service. Diamond Contractor status means factory-backed extended warranties on qualifying Mitsubishi installations that non-Diamond contractors cannot offer.

Mass Save Program — The 3R Difference

3R Plumbing & Mechanical is enrolled in the Mass Save Heat Pump Installer Network (HPIN). Mass Save offers Massachusetts homeowners substantial rebates on qualifying heat pumps and high-efficiency heating equipment.

What sets 3R apart: rebates are applied upfront, as a discount on the contract at signing. The homeowner does not front the full price and wait months for a rebate check — 3R handles the paperwork and takes the money off the top. Most contractors do not do this.

Financing

3R offers consumer financing through GreenSky and Synchrony, with multiple plan options including promotional and reduced-rate structures. Customers can apply quickly and get a decision fast, making full-system replacements accessible on a monthly budget. Learn more at 3rplumbingandmechanical.com/financing.
