"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."

"Andrew did an amazing job. The installation of the electric vehicle charger system only took a few hours, and he was very professional. When we found out the charger plug was European, and therefore upside down from American outlets, he came out and fixed the issue the next day. He went above and beyond the work required and was very thankful for the business. Would 100% recommend this company to my fellow neighbor."

Generator Install questions, answered by experts

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

When installed and used correctly, generators are safe to use. The most critical generator safety tips to keep in mind are:

  • Never use a portable generator inside an enclosed space, as the carbon monoxide exhaust it creates is lethal.

  • Never attempt to connect your generator to your home’s electrical panel independently; hire a professional for this dangerous job.

  • Never overload your generator by connecting more appliances than for which it’s rated; you can damage your generator and appliances or even cause a fire.
