"Travis came to look at the problem on a Tuesday morning. When I explained to him that lights in the house were flickering he became concerned and put my job on the top of his list. Once he arrived he immediately diagnosed the problem as many of the circuits in the box had deteriorated due to moisture in the line. He fixed the bad circuit in question and showed me the problem and explained that due to the age, oxidation, and rust that I may have future issues with the remaining circuits. I decided to replace the entire circuit panel and circuits as well as have a new meter with new wiring and drip lines installed on the exterior of the house, as the old meter was also corroded and detaching from the siding.. Travis returned early the following day at the exact hour we had agreed upon and worked a full eight hours to complete the entire job. His work is exemplary: very neat and methodical and whenever I had a question he would answer it in detail. His work was completed within the 2 days and came to approximately 10 hours in total. He supplied all the necessary materials and had everything he needed on hand in his truck.. I recommend him very highly as a skilled and experienced electrician located in Berkshire County."

"My solar inverter stopped working in my existing solar system, and since my original installer went out of business, I had a hard time finding someone to replace the inverter provided by SolarEdge. It was a small job, and most large companies weren’t interested, while those willing to help were booked out for at least a couple of months. I contacted Justin, and he replaced the inverter within just a few days. He was very friendly, efficient, and offered a very reasonable price. Justin was also extremely knowledgeable, explained everything clearly, and kept me updated throughout the process. He arrived on time, completed the work neatly, and made sure the system was running perfectly before leaving. Overall, his professionalism, honesty, and dedication to customer satisfaction made the whole experience stress-free and smooth."

"It was okay. I think I spent an additional $600. I liked their crew, the owner himself Anthony Berry and he had a person with him. I thought the work that they did was very well done. They cleaned up after themselves. What I didn't like was the fact that they didn't have the supplies that I needed in order to get the job done and then one of them had to leave 3 hours and go get supplies. I was paying for that whole time so it was a little disappointing to me that what I thought could have gotten done fairly reasonably quickly ended up taking a lot longer. My interaction with them and their work were good. I think they should have called me ahead of time and I would have told them what work I wanted done so they could have been more prepared. I felt that they were a little bit unprepared for what I needed done so they just need to be more prepared in terms of having their supplies and stuff. I will not use them again simply because he's actually located very far away like I'm at the very edge of his service area. He's located an hour away and there are other providers with closer proximity to me."

Generator Install questions, answered by experts

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

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.

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.

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.
