"Mr. Green TRULY puts the customer first! He installed a whole house generator for me last August and called to check on us 6 months later because bad weather is coming. Brought me a key and showed me (again) how to add oil. I had several estimates and he beat other prices by several thousand $ AND he installed a bigger generator! I will definitely hire him again and recommend him to every one!! 5 star service *****!!"

"5 stars! Mark Chapman with US Energy Solutions just installed a manual transfer switch box for my portable generator. The work was done professionally, on time, and very reasonably priced. Mark tested the install before he finished and it was perfect the first time. He was knowledgeable and experienced. My next electrical project will start with a call to Mark!"

"Serge is a fantastic electrician and a true professional. Serge was very responsive from start to finish and was.able.to address my project quickly. My project was fairly detailed and required multiple switches and a whole new circuit run for a ceiling fan as well. Serge came first to discuss my project aspirations and what I was hoping to achieve. He was extremely knowledgeable and knew the limitations of my pre-existing wiring and was able to accurately explain why some aspects of my ultimate project goals were unachievable without removing drywall. With his advice and prior planning my project turned out even better than I imagined. Following our initial consultation meeting Serge purchased the required supplies. Again he was responsive and was back 48 hours later to perform the work. He arrived precisely when he said he would and had all the needed supplies. Serge goes above and beyond to minimize damage, he even crawled behind a wall in my basement so I'd have a few less holes to patch. In addition he is extremely focused on being tidy and he always makes sure to clean up after himself as.he works. Serge was extremely thorough and didn't rush through any part of the project. One example of his attention to detail and care is that he even re-anchored the circular drywall cutouts he needed to make with wood inside the wall cavity, so patching and repairing his work was a breeze. While he was working he told me that electricians have a technique to identify their work apart from anyone else. I'll never know what his unique identifier is, because frankly he was so good, you'd never know he was here! I wholeheartedly endorse Serge, he's hardworking, honest, funny, and most importantly he's a normal guy who genuinely cares.about what he does."

"Kevin did an excellent job! We hired him to install (3) bathroom exhaust fans, vent 2 upstairs properly to the outside soffit and install (2) recessed outlets in our den. On time, excellent communication, cleaned up after the job was complete and a fair price / value for the job. I would highly recommend Kevin if you need an electrician at your house. Thanks, John C."

"My initial inquiry was quickly responded to by the business owner. We discussed the problem, and he provided good advice. Based on that I hired him and scheduled the visit. Everything went smoothly and the work was completed to my satisfaction. I would hire DJ Geter again and refer him to anyone who asks me who my electrician is."

Generator Install questions, answered by experts

These advanced generators use a key fob or a smartphone app to remotely start, which is ideal for getting power back on immediately without venturing outside. This feature is more common on whole home generators, but you may be able to find it on large portable generators, too.

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home

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.

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.
