Customers say: Quick response

"Tony was great about strategizing the different issues we had with some of our electrical systems. He brought the supplies he needed, worked the problem so that he could tell me if then wiring was good or if the issues where coming from something else. He also helped make a plan moving forward what we could do if the problem wasnâ t resolved. He has a keen eye for finish work and fixed the botched job from the previous remodel. He stays focused on the work and ensures he doesnâ t overcharge or waste the customers time or money. Iâ d have him back in a heartbeat- great work!"

"I can't thank Ryan enough for coming out to my in-laws home today. Finding a Service Electician in the Flathead Valley is almost impossible. We called at least 8 places and nobody could come out. Some said it would be a couple months. Ryan made time at the end of his workday to stop by on the way home to help us. He fixed our problem, and we were good to go in 30 minutes. I can't thank Ryan enough for going out of his way for us. The Valley needs more Service Electricians like this."

Generator Install questions, answered by experts

In most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between $50 and $250, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you—and might be required to do so by your building department—but you’ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.

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’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.

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

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
