What Happens After You Book
You should never have to wonder whether someone is actually coming, or what it is going to cost when they get there.
1
You get it in writing
A text confirmation with your appointment window, so it is not just a promise someone made on the phone.

You know who is coming
When your technician is dispatched you get their name and photo, so you know exactly who is knocking on your door.
3
You see the price first
We diagnose, explain what we found, and give you the price before any work starts. Nothing happens until you say go.

The paperwork follows
Invoice, permit records, warranty registration and any rebate filing handled and sent to you. Not left for you to chase.
Local. Accountable. Experienced.
Why South Shore homeowners choose 3R
3R Plumbing & Mechanical was established in 2022 by Ross Hunt—a U.S. Army veteran, Massachusetts Master Plumber, and EPA-certified HVAC technician with more than 18 years in the trades. What started as one truck is now a full South Shore team bringing plumbing and HVAC expertise together under one roof, supported by an office staff that answers calls around the clock.

Factory-Certified Equipment
Equipment Brands We Install & Service
We are picky about the equipment we put our name on. Every line below is one we install, stock parts for, and stand behind — and we service virtually every major brand, no matter who installed it.
Two certifications we actually earned. As a Mitsubishi Diamond Contractor, systems we install and register within 90 days carry a 12-year parts and compressor warranty — the standard is 5 and 7. As a Navien Certified contractor, we commission every boiler and tankless unit with combustion analysis so the 10-year heat exchanger coverage stays intact.
Mitsubishi Electric
Ductless · Cold-Climate Heat Pumps
Our flagship line. Hyper-Heating models hold rated capacity into single digits. Diamond Contractor warranty eligible.
Fujitsu
Ductless · Cold-Climate Heat Pumps
Airstage inverter systems. XLTH outdoor units are rated to operate down to −15°F with a heated base pan.
Bosch
Ducted Heat Pumps · Ductless
IDS inverter systems drop into existing ductwork. IDS Ultra is the cold-climate model on low-GWP R-454B.
Trane
Furnaces · Central AC · Ducted
The durability benchmark for homes with ductwork — installed as properly matched, load-calculated systems.
