"What I love about VMA is that you can get Residential electrical work quoted 2 ways: Time/Material (emergencies), or they can send a man out and quote the job. You may also take detailed pics, send it in and they can quote it that way. My old electrician they did everything old school w calling, & didn't even like emailing, but not VMA who texts, calls, and emails. 2 professional, Journeymen Electricians did 3 separate days of work last month at my house, from the VMA Residential/Service division. They replaced/installed 7 exterior lights, replaced 2 exterior outlet fixtures with Arlington housed outlet boxes, installed one new Arlington, extended light fixture wiring and 2 doorbell wires, and exchanged a transformer for a larger one, to handle the video loads from Nest and Arlo doorbell cameras. I purchased all the fixtures, & doorbell cams. They supplied the Arlington boxes. The 2 electricians were very efficient, quiet, fast and clean. They made sure fixtures were leveled, and working. One of the 4 glass sides of the exterior light fixture broke cleanly and they honestly brought it to my attention, vs just burrowing it. I just double taped it w clear packing tape, and he put the glass in the rear of the fixture so it wouldn't be seen. I didn't want that to hold up the light install, and will deal w the Amazon merchant I bought light fixtures from afterwards. I had a lot of other construction going on, and the 2 electricians were able to do a lot in the timeframe they had despite all the other noise/work/men around. They fixed cut outlet wires from a bedroom new window installation, moved an outlet 3" to accommodate a stud inserted to shore up the new window. The cut wires were a surprise, and to get the city's Wiring Inspection approved, Cindy the Svc Manager, was very helpful in getting the electricians here stat, & the Building Inspector also stat, who had a 3 wk backlog. I had VMA Electric quote me for a porch and their pricing was much better vs another electrical competitor in Marlborough. The guys are Journeymen level, so aren't outrageously priced like Master Electricians, in the same town, who I had been using. When the Residential side has a lot of work, they can smtms pull guys from the much larger Construction Division. In all, VMA had to come out 3 times, bec the work was staged in between inspections. I love their work and do not hesitate to highly recommend. Just know electricians are expensive, and it cost $2,300 total, up front for all that work. Had I used the Master electricians the bill would've likely been double, as found out they were double/triple charging me the town's Permit fees in addition to double all the same work VMA does."

For emergency services, please call 781-933-6387. N.E.T.R., Inc. is here to help homeowners install the best heating and cooling systems that fits their needs. Since 1989, we’ve installed heating and cooling systems in Boston and its surrounding areas, tackling tough problems that our clients face. Our goal is to ensure our clients have energy efficient, quiet, reliable systems so they can live their lives to the fullest both at home and at work. Our dedication to our customers’ needs is what drives us each and every day. Our approach to temperature control and comfort has helped us become one of the most respected names in heating, cooling, and refrigeration in New England

"Before installing a mini-split, the sales person told me that I'd need to cut down an interior shelf to a specific height. I paid a handyman $400 to do exactly what the sales person instructed. Later on, N.E.T.R. came and did the installation; however, AFTER the installation, a technician told me that they hadn't accounted for the vent opening and closing and that the shelf would need to be further cut down. As you can imagine, this type of service is rather ridiculous. If they knew that the shelf would need further cutting, they should have NOT installed the unit. I have called N.E.T.R. six (6) times in three weeks, and no one has called me back about this issue. After paying for the unit and for a handyman, it's ridiculous that I have AC that is compromised because no one with the company thought to properly measure the space so that the work by the handyman could be done once. At this point, I'd like for N.E.T.R. to take care of this for me."

He also showed up on the day of the project to introduce the two electricians that would be doing the work. The team was courteous, professional, and did a great job installing the lights. They also were careful to cover the room with tarps to minimize dust and cleaned up the workspace afterwards. If we have a future need for an electrician, PW DiMasi will be our first call."

Generator Install questions, answered by experts

You can determine what size generator you need by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together. 

A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you’ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace. In these instances, a whole-home generator is your best bet for running your critical equipment.

Yes, whole-house generators run constantly for extended periods. Whole-house generators can run for longer periods of time than portable generators, but be careful. First, they may need regular applications of engine oil (as frequently as daily), depending on the engine design. Second, running constantly for several days will increase the wear and tear on the generator and shorten its lifespan.

As long as they have enough fuel, whole-house generators can run for weeks at a time (400 to 500 hours) without suffering too much wear and tear. However, this type of extensive use isn’t ideal if you want to extend the life of your generator.

Two important points. First, some generators may need you to periodically check oil levels every day or so and refill as necessary for safe operation. Second, if your generator uses a fuel tank, keep it regularly full so it doesn’t suddenly shut off. Many backup generators can run through a full tank in a day when they are powering large portions of a home.

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

No, you cannot plug a generator directly into a wall outlet in your home. Plugging in a generator without an interlocking kit, extension cord, or wall outlet receptacle is incredibly dangerous and can cause back-feeding—power from the generator back-feeds into utility lines. Also, if the main power comes back on while your generator is on, it could damage the generator and cause a house fire.
