"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."

"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

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

If you’re wondering whether gas generators produce carbon monoxide, know that natural gas generators do not produce carbon monoxide if they are functioning properly, as natural gas burns cleanly. However, if the generator malfunctions and the gas does not burn completely, there is potential for carbon dioxide to be produced. To prevent malfunctions, it's crucial to perform regular maintenance, including running the generator weekly and scheduling professional inspections every 6 to 12 months. Also, be sure to test your carbon monoxide detectors regularly to ensure they function in the rare case of the generator producing carbon monoxide.

Carbon monoxide emissions aren’t only dangerous to human life, but they also harm our planet. While natural gas generators emit lower levels of CO than other fuel sources, there are still ways to reduce emission levels. For example, shop around for an eco-friendly generator that complies with current emission standards. Also, make sure your generator is serviced regularly to avoid CO buildup.
