My name is Nektarios "Nick" Arsenis and I am the proud owner of Naxos Electric. My company is named after the island I was born and raised on in Greece. It was there at the early age of 15 that I began my electrical career, which I continued to pursue when I came to the USA in 2000. Naxos Electric is founded on the same ethics and values that I was raised with: reliability, great communication, integrity and quality work. I strongly believe in giving my absolute best on all projects and look forward to assisting you with your next task or project. We are fully licensed and insured. Call us today at (401) 330-0175 for a free estimate!

"Aside from the fact that my lights are working now, I want to say how much I appreciate Nick's professionalism and prompt attention to my problem. The power outage was in an office area that I needed access to for work in the evening and Nick (hearing the desperation in my voice) moved his schedule around and was willing to come to my home 90 minutes later. It was after hours and he was willing to do me a great kindness at a reasonable cost. What more could you ask?"

Full Service Electrical and installation provider. If you suspect your electrical system could be damaged or malfunctioning, contact us right away. We will send a knowledgeable electrician out to identify the exact issue that is affecting your system. However, we do far more than just repairs, from LED lighting installation to electrical panel upgrade. At Kelco Electric, it's our job to make sure that all our electrical repairs are done carefully and correctly. When your electrical system is in need of repairs, it's dangerous to let the problem remain unsolved. Electrical systems are complex and interconnected, so when one component isn't working properly, the entire system is at risk. We know that your life is busy and dealing with electrical problems or upgrades isn't exactly on the top of your list. However, electrical work isn't something to be taken lightly. This is why our electricians are here to make sure you and your family are safe from electrical problems. We will always work to make sure your needs are met and all work is completed to electrical codes at reasonable prices.

"Kelco Electric did a great job. Randy and Isaiah were very professional and efficient. Arrived on time and had job finsihed within one hour. I will hire them again when I need electrical work."

Generator Install questions, answered by experts

Most homeowners won't be able to claim a home generator as a tax write-off. However, a whole-house generator may be tax-deductible in certain situations depending on its purpose. For instance, if it's needed to power essential medical equipment, it may qualify as a medical expense deduction. Also, in some cases, businesses can deduct a generator as a business expense if it supports operations. Always consult a tax professional to determine eligibility based on your specific circumstances and the applicable IRS regulations.

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

The cost to install a whole-house generator averages at $5,200, but costs can range from $1,500 to $8,900, depending on the type and size of the generator, and the labor required to install it. To find the best deal while still ensuring the unit meets all the needs of your household, hire an electrician to calculate the electrical load of your must-have appliances and electronics beforehand so you don’t pay for more power than you need. As always, be sure to get at least three quotes to find the ideal fit for your needs and budget.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

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.
