"Peter is a professional! I got a few quotes and while Peter's wasn't the lowest, I could tell he takes pride in his work and would make sure the job was done correctly. On the scheduled date, he and two workers showed up on time and got to work. The work we had done included installing a fan brace, medallion, and chandelier in our living room, installing a medallion over a chandelier in our guest bedroom, and installing a medallion on a chandelier 20+ feet up (that required two ladders and a plank straddling a staircase). The guys worked fast and once the hard stuff was done, Peter left it to his guys to clean and wrap it up (which is good because Peter's hourly rate is higher than his workers). Overall, was very satisfied with their work and will be hiring them again for my electrical needs."

Markarian, CEO Customers can email us at [email protected].
"We needed help to change over several interior ceiling light fixtures to new pieces we had purchased and we needed bigger and stronger garage ceiling lights. In addition to the work that was needed, we also wanted to request estimates on 3 projects for the Spring - installation of an exterior light post and lamp, running an underground line out to a back garden for an outlet and to fix our kitchens under cabinet lighting. Their electrician arrived promptly at the expected time and was very courteous and professional. He was very well organized and efficient. We discussed the options for the garage lights and he recommended going with 2 x 48" LED panels and we checked Home Depot online, found a good product and I went over and made the purchase. He did the installation in no time and the lighting is fabulous. Overall, great work! We got the estimates a day later and 2 of the 3 look very workable and we will go forward with Markarian for those projects. The price for the undercabinet lighting was about 10 x more than I would have expected so we'll hold off on that. Maybe I can do that one myself. ME is a reliable and very professional group and you won't be disappointed."

FAQs for generator installation projects in Somerville, MA
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 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.
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
