"These pros were absolutely amazing.Talk about "an on-time" company....for the consultation.. So, this was the third company we asked for an estimate!! We were literally blown away when they came in between $800-almost $2000 less than any of the other estimates we got. Yes, we initially were a bit apprehensive, but their Master Electrician laid it out for us, same identical configuration from our electric panel in the unfinished room to the garage for the charger installation. Of, course, why would we not hire them? They had experience with these type of installations. Parker and his guys...were always available if we had "just another"question. Yes, we hired them...and they lived up to everything. Always on time....no hiccups, no changes, just a smooth---no stress---installation. We will always go back to them, if we need electric work to be done. Highly recommend this company. We are so thankful that they got in touch with us from my request at ANGI. Thank you Parker and TEAM!!"

"As first-time homebuyers, finding an electrician was stressful. We compared many quotes, but at the first estimate Derrick's confidence and knowledge earned our trust right away. He installed lights in our living room, all 3 bedrooms, added dimmers, and ran dedicated circuits with waterproof outlets for our bidets. He handled the permit and inspection, always told us what he was doing before starting, communicated quickly, and was very flexible. It's very impressive that he started working around 6am, super hard working! The details really stood out. He used a laser to line up the 6 living room lights perfectly, and matched all the bulb colors without us asking. The room looks so much brighter and more fancy now. Upgrading to dimmers was a thoughtful touch too. Derrick is honest, responsible, and just a really nice guy. It's rare to make a friend through a house project! We'll be recommending him to all our family and friends. Highly recommend! ❤️"

Generator Install FAQs, answered by experts

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.

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.

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.

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.

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