"New to the area, I needed a hookup for an emergency generator and EV charger. Cole came to my home, took the time to discuss different options and answer questions, and provided a detailed, written estimate, all the same day as my initial inquiry. The project was completed within a few days. His price was very competitive and his work meticulous. A true professional."

"Vinny was an excellent electrician. From start to finish, he was easy to deal with and we had clear communication throughout the entire process. He provided great service at a fair price and did a very good job installing light fixtures, repairing broken outlets, and installing a 40amp outlet so I can charge my electric car. I would recommend him and do business with him again."

"Wow, they just left and I am so beyond impressed with everything, from start to finish. Adam helped with our estimate and was a pleasure to work with. He came next day for our estimate and from there, went above and beyond to answer every single question and concern of mine, he was fair in his pricing, very timely in his responses and even remembered the layout of our home when I called a month later. They were even able to schedule the job next day due to the inclement weather. Jim and Matt arrived early and were so courteous and pleasant to work with (they were even extremely considerate of my infant's nap schedule). We had them install two new outlets for ac's and electronics and they had to snake the wires in impossible places. Jim listened to every single one of my concerns and came up with excellent solutions and they left everything in better condition than they found it. When I asked if there was another way to get the job done, he listened and offered to change his plan. It was so nice having a contractor actually listen to you and work with you. I will definitely be hiring them again - I am so glad I finally found an electrician that is respectful of an older home. Thank you Adam, Jim & Matt! You guys rock!"

"Fast and super helpful. Gave me a proposal right away. Started work same week. If deviations were needed, was specific on what and why. Reasonable and fair pricing, and honest about their capabilities and areas of expertise. Professional team and went out the way to provide additional references for other concerns. I also appreciated the video Fabio took to show me the before and after, especially in areas I was unable to see."

Generator Install questions, answered by experts

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. 

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.
