"In Phaze Electric did a phenomenal job at our house. It was a pleasant experience from sales with Keylin, Jessica with Permitting, Chris and Tony in the Backoffice, and the electricians that came onsite Joe Brancaccio and John Sarden. Our job was to replace a 200 AMP panel, meter base, and install a generator interlock. Each person took great care and was nice to work with. Joe specifically has a great way with people and will go out of his way to make sure things are done right! We can sleep soundly knowing that we were taken care of by In Phaze and that their work will last for years to come."

"Ryan is pleasant, knowledgeable, took time to explain the process fully and did a great job. He gave me an estimate over the phone, called back to say he had a cancelation for the next morning and we scheduled. He was prompt, approachable and there were no surprises. He did a great job installing a grounded outlet for my garage door opener, cleaned up after himself and asked if I needed help returning boxes to their shelves in my garage. I will definitely call Ryan/Smartron Electric again if I need electricall services."

"I hired Ben to install a generator plug and a few misc electrical duties. He was very professional, timely, and the work is unmatched. During one of the electrical outlet installs he brought parts of my home up to code which I greatly appreciate. He talked me through the different options on what he recommended and I trusted his judgment-luckily everything worked out perfectly. I highly recommend this young man and itâ s always nice hiring small American business."

Generator Install FAQs, answered by experts

While natural gas generators are costly, they’re a great option for standby power due to the reliability of natural gas as a fuel source. Unlike other fuels, natural gas is delivered through underground pipes, making outages extremely rare and less likely to be affected by the elements. As long as the area isn’t prone to earthquakes, they offer an unlimited supply of natural gas that doesn’t degrade over time or require storage in tanks.

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.

In most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between $50 and $250, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you—and might be required to do so by your building department—but you’ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

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.
