"Christian was helpful, answering my questions and showing me where my generator could be placed and explained the installation process, His visit was not to repair a generator, but to get me a quote."

"The team from the office to the tech all the way to the head of the company was great. They came out and knocked out the projects I had lined up. They were very professional and cleaned up once they were done. I would definitely hire again!"

"Great follow through, good pricing. The generator required several trips and follow-up items because it required different inspections. They did a great job at following up on these steps and the generator works perfectly. Since that time we called them for some smaller electrical jobs. They are very detailed oriented, an example would be that I gave what I thought I wanted and they gave feedback based on their experience showing a better way to do it. I welcomed this and was happy they suggested it."

"Matthew was prompt and direct in his recommendations. We were not entirely sure of our options and he ultimately recommended a cheaper solution! In this case, we were looking to have all the outlets grounded in our home, and, based on the area and our needs, Matthew offered the idea that we install a sort of surge protector for the entire house."

"Drew, the owner of Walker Electric was the technician that actually showed up to do the work. I had him install a ceiling exhaust fan in my bathroom. He did excellent work replacing the old one with new and didn’t do any unnecessary drywall damage. I also had Drew install under cabinet strip lighting in my kitchen that came out looking wonderful. His pricing was more than reasonable and his quality of work was top notch. I would recommend Walker Electric for any of your electrical needs and I will absolutely be using them again in the future!"

Generator Install questions, answered by experts

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

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.

In most cases, there are no tax credits available for home generators. However, that’s a general statement that applies to federal tax credits, so you might have access to state or local tax incentives. You can check the Database of State Incentives for Renewables & Efficiency (DSIRE) for more information about your area. If you hire a reliable home generator installer, they should also know if there are any state or local perks you can use to reduce your installation costs, including tax breaks and rebates.

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
