Customers say: True professional

"Travis and his team do outstanding work! Brent, Nick and Aiden did the majority of the project. I can’t say enough about their professionalism, skills and timeliness. They are extremely hard working individuals who clearly take pride in the work they do for others. They put in a new panel and rewired our entire house built in 1902 -not an easy job- and added multiple ceiling lights, outlets and switches where none existed before. They were very clean, used drop cloths and repaired holes. There was minimal dust, so my mom could live in the house during the work- nothing like what other people described when they had similar work done by other companies. They answered questions and replaced switches quickly when we realized the original color we picked did not look right. They were respectful and timely and the entire process went quicker than we thought possible. Travis and Brent were available by phone/text if we had questions on days not working. Mom and I highly recommend hiring!"

"Frank and his team always arrived on time and were able to start the work the week I requested a quote. They answered my questions and helped me to make decisions about what needed to be done. Had numerous lights/ceiling fans installed, outlets changed, and a doorbell installed along with the utility boxes being redone among other things. I would hire them again."

"My solar inverter stopped working in my existing solar system, and since my original installer went out of business, I had a hard time finding someone to replace the inverter provided by SolarEdge. It was a small job, and most large companies weren’t interested, while those willing to help were booked out for at least a couple of months. I contacted Justin, and he replaced the inverter within just a few days. He was very friendly, efficient, and offered a very reasonable price. Justin was also extremely knowledgeable, explained everything clearly, and kept me updated throughout the process. He arrived on time, completed the work neatly, and made sure the system was running perfectly before leaving. Overall, his professionalism, honesty, and dedication to customer satisfaction made the whole experience stress-free and smooth."

Generator Install questions, answered by experts

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

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.

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.

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.
