"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

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.

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.

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.

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.
