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."

"I hired Mike for a back-up generator installation. Very quick response, very good communication: he explained everything thoroughly, and invited questions. Mike is very professional, while still being personable and pleasant to deal with. I would call him again for future work."

"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 FAQs, answered by experts

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

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.

Costs range from $500 to $2,500, depending on generator type and installation complexity.
