"They did excellent work on many different items. Had a light installed over the sink (replaced a canister with light), re-wired outlets for kitchen remodel, and installed Ring doorbells. Showed up on time (key for me) and did nice work on all of the items. I would definitely have them do any other electrical work for me."

"Shawn Powell scheduled an installation and overview of my security system for 5/14/2021 and he was here promptly on that day. He had to detour on his way to my house but he texted me to let me know he was delayed. Shawnâ s customer service is impeccable. When he got to my house I had on my mask, he respected my home and put his on. When he had everything installed he gave me all the instructions I needed to use my system. If you want great customer service, a professional installer and top of the line security system for an affordable cost, Shawn is your man. I highly recommend him."

"Mr. Bailey was absolutely amazing. I have an older house and even simple projects become complicated fast. Mr. Bailey visited my home three different times and every time was a great experience for me. He showed up on time, every time. He was very easy to contact and he kept me informed of what was going on at every step of the job. He was incredibly professional even when my old house threw curveballs at him. I am so impressed with all of the work he did for me and my spouse and I will absolutely recommend him and hire him again if/when we need more electrical work done. Mr. Bailey is a joy to work with and he truly cares about his work. I can’t say enough about how much I appreciate him and his dedication to figuring out the puzzle of my house and making sure me and my family are safe in our home."

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.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.
