"John was very accommodating and understood exactly what we needed. He was prompt, courteous, and kept me informed throughout the process, as the work was done for my mother while I wasn't there. My mom was very pleased with her ceiling fan light fixture installation and the price was very reasonable. I would definitely call him again for any other job I need done. Thanks again John!"

"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!"

"i recently had a tesla charger installed, and i am extremely satisfied with the service. the electrician did an outstanding job he was professional, knowledgeable, and completed the installation much faster than i expected while maintaining excellent quality. the work was clean, efficient, and everything was installed perfectly. on top of that, his pricing was very reasonable compared to other estimates i received. it’s not often you find someone who delivers great workmanship, works efficiently, and offers affordable rates. i highly recommend him to anyone needing electrical work or an ev charger installation."

Generator Install questions, answered by experts

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.

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.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

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.
