"I was having an exterior outlet installed. The job was quickly evaluated and an estimate was provided. I didn't really see a break down of materials versus labor, so I'm not completely sure of the basis for the costs. It was super convenient with very quick response. They made sure that the work area was cleaned after completed. Very friendly tech. Very comfortable having them in my home."

Customers say: Quality work

"The price was higher than other estimates but I got the feeling that they really knew what they were doing and the electricians made a couple of suggestions that really turned out to be good ones. They did a very high quality installation and couldn’t have been more professional and cordial."

The Jensen family’s history in electrical work spans three generations. It began with Kyle’s grandfather, who spent 47 years as a maintenance electrician with Mountain Bell. That dedication to craftsmanship continued with Kyle’s father, a well-respected electrical contractor in Southern Utah. Following in their footsteps, Kyle entered the trade early—starting as an apprentice at 16, earning his Journeyman license in 2002, and achieving his Master Electrician license in 2006. With that deeply rooted family foundation, he brings decades of hands-on knowledge to every project.\n\n

Generator Install FAQs, answered by experts

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.

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home. 

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.
