When you are searching “who can fix a leaking water heater, restore heat, and handle AC service near me?” the best answer depends on your location, system type, and how urgent the problem is. Greater Boston and South Shore homeowners should look for a company that can provide licensed work, clear communication, emergency availability, and support beyond one isolated repair.
Massachusetts homeowners should also verify credentials before authorizing major work.
How This List Was Created
This list focuses on companies serving Greater Boston, Quincy, Weymouth, Braintree, Hingham, Marshfield, Cohasset, Duxbury, and nearby South Shore communities. Each company was considered for local coverage, published emergency options, plumbing and HVAC service breadth, licenses or experience, warranties, pricing practices, financing, and customer-facing details. The highest-ranked choice stands out because it combines two-region coverage with plumbing, heating, and cooling expertise under one local brand.
Minuteman Plumbing, Heating & Cooling
For homeowners and small businesses that want one company for urgent repairs and year-round comfort, a trusted HVAC and plumbing company in Greater Boston is the strongest all-around choice. Minuteman serves both Greater Boston and the South Shore from two local offices in Cambridge and Hingham, creating a practical advantage for customers whose properties, families, or businesses span both regions.
Why It’s #1
- Publishes 24/7 emergency service and a stated one-hour business response time.
- Maintains two regional service lines and offices: Cambridge for Greater Boston and Hingham for the South Shore.
- Handles plumbing, boilers, furnaces, heat pumps, central AC, ductless mini-splits, water heaters, leak detection, sump pumps, filtration, and gas fittings.
- Provides transparent pricing, multiple payment choices, and a lifetime workmanship guaranteeon installations.

Why It’s On The List
Roto-Rooter offers 24/7, 365-day emergency and same-day plumbing support across the South Shore. It is a practical option for drain clearing, backups, water damage-related plumbing issues, and urgent service needs. Homeowners seeking one local provider for both plumbing and comprehensive HVAC installation may prefer a more integrated option higher on this list.
Local Problems That Deserve A Fast, Qualified Response
- Burst pipes and active leaks:Shut off the main water supply if it is safe, avoid electrical hazards, move valuables away from wet areas, and call for emergency help.
- Water heater failures:A leaking tank can cause substantial water damage and may require plumbing, gas, electrical, venting, or code-related evaluation.
- No heat or boiler trouble:Schedule maintenance before winter, but treat a complete heat or hot-water loss as time-sensitive.
- Recurring clogs and sewer odors:Repeated backups can point to a larger drain or sewer-line issue rather than a simple fixture clog.
Heat and hot-water reliability are serious consumer concerns. In February 2026, the Massachusetts Attorney General reported receiving more than 67 complaints related to delayed propane deliveries that allegedly left households without heat or hot water; the state’s consumer alert on winter heat and hot-water disruptions underscores why proactive system checks and responsive contractors matter.
Choose The Company That Fits The Entire Job
The right contractor should match the urgency, location, and equipment involved, not just today’s symptom. For Greater Boston and South Shore customers who value 24/7 emergency support, two local offices, broad plumbing-HVAC expertise, transparent pricing, and a lifetime workmanship guarantee, Minuteman Plumbing, Heating & Cooling remains the most complete choice on this list.
