New England winters are no joke, and neither are the nor’easters that knock out power for days at a stretch. Having a reliable backup power source starts with finding an Electric Generator Shop that knows what it is doing one that handles the sizing, the installation, and the electrical hookup all under one roof. JMR Electric has been helping homeowners and small businesses across Stoneham, MA get set up with standby and portable generators that actually work when the lights go out.
A lot of people grab a portable generator from a big-box store and call it a day until they realize it cannot power their furnace, well pump, or refrigerator all at once. Our team walks through your home’s actual power needs, helps you pick the right unit for your square footage and appliances, and handles every step of the whole-house generator installation and wiring from start to finish. No guesswork, no undersized equipment, no surprise callbacks.
A standby generator sits outside your home on a concrete pad, connected to your natural gas or propane supply, and fires up automatically within seconds of a power outage day or night, even when nobody is home. Stoneham residents who have lived through multi-day outages know exactly how valuable that automatic response is. No fumbling with extension cords, no running out to the garage, no carbon monoxide risk from a generator sitting in the doorway. Our licensed electricians install the automatic transfer switch that makes all of this possible and makes sure it is wired to code before the job is called done.
Power outages in Stoneham are not a matter of if they are a matter of when. Ice storms, summer thunderstorms, and the occasional utility failure leave neighborhoods dark for hours or days at a time. Working with the right Electric Generator Shop means your family stays warm, your sump pump keeps running, your food does not spoil, and your home-based work does not grind to a halt. JMR Electric brings the full picture proper sizing, clean installation, code-compliant wiring, and ongoing service so your backup power is ready every single time you need it. Fill out the form below or give us a call and we will get your quote started today.
Generator installation is not the same as plugging in a window unit. It involves pulling permits, running gas lines in coordination with your utility, sizing a transfer switch to match your electrical panel, and making sure the whole system passes inspection. Our crew handles all of that not just the electrical piece. We show up with the right equipment, work cleanly, and do not leave until the generator has been tested and everything is confirmed working.
We service what we install, too. Annual tune-ups, load testing, battery checks, and oil changes keep your unit running reliably so it is not a gamble every time a storm rolls through. JMR Electric is the kind of shop that answers the phone when you call back six months later with a question.
Experience the JMR difference.

Two professional, hardworking young men arrived at my house promptly, insisted on taking off their salty icy boots to not track it through the house, and then worked collaboratively and methodically to solve my problem. They even explained what was wrong and answered my superfluous questions kindly. JMR Electric should be proud.Posted on Google Joe HTrustindex verifies that the original source of the review is Google.

Common questions from Stoneham, MA homeowners about generator installation and backup power
Sizing depends on which appliances you need to keep running during an outage. A small portable unit can handle lights and phone charging, but if you want to power your furnace, refrigerator, sump pump, and a few other circuits at the same time, you are looking at a whole-house standby unit in the 14- to 22-kilowatt range for most average-sized homes. Larger homes with electric heat or a well pump may need more. Our team does a load calculation before recommending anything — we want the unit to actually cover your needs, not just sound impressive on paper.
If your home already has a natural gas line, connecting the generator to it is usually the more convenient choice — there is no tank to refill and no risk of running out of fuel during a long outage. Propane is a good option if natural gas is not available at your address. Propane stores well and can power a generator for days if you have a large enough tank. Both fuel types are reliable; the right answer depends on what you already have at your property. We go over both options with you and help you figure out which setup makes more practical sense for your situation.
Massachusetts building codes and most generator manufacturers require the unit to sit at least 18 inches from the house, with additional clearances from windows, doors, and gas meters. Most installations end up somewhere between 18 inches and 5 feet away from the foundation, depending on the layout of your property and where the transfer switch is located. We survey your yard, account for local setback rules, and pick the spot that meets code while also making sense for your property — not just the closest flat patch of ground.
Most manufacturers recommend a full service once a year — covering an oil and filter change, spark plug check, battery test, air filter replacement, and a load test to confirm the unit will start and carry a real load under pressure. Your generator runs a brief weekly self-test on its own, but that is not the same as a proper annual inspection. Stoneham winters put real demand on backup power systems, so staying current on maintenance is what separates a generator that fires up reliably from one that surprises you at the worst moment.
