"Matt was very creative and thoughtful about the best way to install an electrical vehicle charger when he needed to work through some obstacles in an older house. I anticipate using him for other projects around our house and am happy to recommend him for the installation of Level 2 home charging."

"First II had an EV charger installed. Nicholas was the first to be completely transparent about what it would take to do the installation properly, and on top prepare our stove outlet to induction â both major consumers of electrical power. As a followup, since our electrical panel was a complete mess, I had him install a new panel neat and properly with modern breakers. I would definitely hire him for any other electrical jobs I may have in the future. Highly recommended."

"I bought my unit from NETR in 2018. It worked fine until we discovered it wasn't blowing any cold air. I made the big mistake of hiring someone a family friend recommended and they diagnosed it incorrectly and then basically disappeared on me. Anyway, it took a few weeks but they repaired it today and I was impressed with their courtesy and getting the job done very quickly and successfully. I felt like I was being dealt with honestly. Thanks, Jared and Jack. I should mention I paid about $300 for the refrigerant today. I don't know what the final cost will be but probably a bit over $1000."

"I am a landlord and was in desperate need to have a few outlets within a rental unit serviced as they were RED flagged by city of Boston ISD for non-grounding. I called a few local electricians and none could fit me into their schedule. I remembered the Homeadvisor adds and went online searched for the services I needed and filled out form. And within 15 minutes Ray from Daly Electric, Inc. gave me a call, he identified himself and asked me what services I needed. I explained the situation and Ray gave a call back with a quote and an appointment for Monday morning within 20 minutes. Keep in mind that we first made contact on Friday morning. Ray was really convenient as I could not be on site. I left the keys to the unit and he called me when he got to the property. Ray, called me once again on inspection to confirm the work as well as alert me about polarity issues with other outlets in the unit. Ray gave me a competitive price and service I am happy with. My perception of Ray and Daly Electric, Inc. from this one instance is that they are clear in their communication and follow through which made feel I was making the right choice in hiring his services. I would say I recommend Ray from Daly Electric, Inc. and would consult and use their services again."

"Adam called me immediately and met me that same day. I hired the company and they cut my grass that same day. They used a ride on mower and my land is uneven so some areas were shorter than others. Two days later they spread 10 yards of hemlock mulch and recut some areas of my grass with push mower. They will use a push mower in the future. My yard now looks beautifully landscaped. Communication is definately key with this company. They aim to please!!"

"Empower Electric did a great job. I had them rewire my Multi Family home in Everett. I also had them rewire my second floor of my home in Wilmington. They also did some outside lights for me as well. Jimmy was very professional and gave me a great price."

Generator Install questions, answered by experts

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.

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.
