At WIRED Electrical Contractors, we’re pursuing excellence: from your initial consultation to our superior warranties and follow-through. Owned and operated by master electrician Paul Crowley, our team of trained and certified master electricians provide MetroWest MA homeowners with quality craftsmanship, upfront pricing, and attentive responsiveness throughout every project phase. Our focus on quality has earned us the Angi Super Service Award for ten years running. We are a full service residential electrical contractor. We specialize in home EV charging installations and are Tesla trained and certified. We are also certified installers with Qmerit, Chargepoint, and ClipperCreek.

"Paul was on time and got to work right away. He was very respectful of my home and put on boot covers as soon as he entered and placed a plastic protecter on the floor beneath where the fan was to be installed. Very neat and clean. While performing the installation, he informed me that the mounting bracket that was used for the original fan was only rated for a light fixture and showed me the difference between the screws used for the current bracket and the proper one. He quoted a price for the proper bracket and I gladly obliged. He also installed a new wall switch that controls both the fan and light kit wirelessly. The final results are perfect. Before he left, I asked him about replacing my noisy bathroom fan with something quiet and with a heater. Since a new line to a circuit breaker would have to be dropped, he checked out my electrical panel. He informed me that my current electrical panel was not up to code and who ever worked on the panel to add new breakers overloaded the panel (22 breakers in a 20 breaker panel). He was not pushy at all in having the panel upgraded to the proper size but did inform me of potential issues I could have in the future and that it is not up to code. I am extremely satisfied with the job Paul did and I plan on having Paul perform the other needed services I require. A+."

"The installation went quickly and easily for us, and the level 2 charger is just where we need it. I am grateful that I can park, get charging, and be in the house with a cup of tea within a few short minutes. It is so convenient, and the car charges quickly. The VMA installers were so helpful in getting me started once the installation was finished. We have had VMA do quite a few household projects for us, and everything about them is excellent, from scheduling, to the actual work, and to billing. Highly recommend!"

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."

FAQs for generator install projects in Belmont, MA

When maintained properly, a whole-house generator can last up to 20 years. Costs to maintain and repair generators vary by location and type of generator, but you can expect to pay about $150 to $300 per year for annual generator maintenance checks. An experienced generator service technician will inspect your generator’s engine filter, starting mechanism, fuel, lubrication, and coolant levels to keep your generator in good working condition for as long as possible.

Installing a whole-house generator costs about $5,000 on average. Prices range from $1,550 to $8,500, depending on size, brand, fuel type, and assembly. The size of your whole-house generator is the most significant cost factor, with large homes with high energy demands costing the most to power. Types of whole-home generators include:

  • Portable generators with 1kW–7.5kW capacity: $500–$2,000

  • Partial generators with 9kW–20kW capacity: $2,000–$6,300

  • Whole-house generators with 22kW–48kW: $5,000–$18,000

When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 watts

Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running. 

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

The value of installing a whole-house generator is that your home has guaranteed power, even if the power grid in your area is down. Whether a whole-house generator is worth installing in your home depends on how often you use it, your home’s location, and your lifestyle. For example, installing a whole-house generator is likely worth it if you:

  • Experience frequent or prolonged power outages

  • Work from home

  • Store a lot of cold food

  • Have a sump pump

  • Have a pump for well water

  • Use electronic medical devices

  • Live in a climate requiring heating or cooling
