"Jason and his team with Cotti-Johnson did an excellent job updating our electrical boxes, installing the washer/dryer hookup, and getting us setup with a generator! Sam, our assigned electrician, even took the time to go through the entire operation of the generator from A-Z. I would definitely recommend them for any electrical work!"

"Russell did an outstanding job. He went to our house, saw what had to be done, explained everything, and his fee was more than fair. He did an annual maintenance on our generator (and ordered a spare key for it), installed an electrical outlet (while having to cut away wall & work around studs & water pipes), replaced light switches, disconnected an old intercom system, removed a circuit from breaker box. He will be the professional I call, if I need an electrician. Totally recommend."

"Expensive but professional. The electrician that did the work was excellent and seemed.to enjoy explaining what he was doing and why it had to be done that way. I felt like I learned something while he installed ceiling lights. He also cleaned up after himself like he'd never been there."

"We initially called a different electrician who said he would come by at the end of the day to assess what was needed to be done in our home. Not only did he not show up, but he never called us to schedule the work. After waiting 3 days, we called Anthony and left a voice message. Anthony returned our call the next morning, and scheduled to do the electrical work the very next day. Anthony and his worker showed up on time and figured out the electrical problem within minutes. They did an excellent job installing new wiring. They were very professional, courteous, and respectful of our home. We're glad the initial electrician never showed up because we have definitely found our new electrician for any future electrical needs. We highly recommend Anthony to anyone looking for a professional electrician. Thank you, Anthony!"

Generator Install questions, answered by experts

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

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. 

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.
