"Lucas and Josh arrived the very next morning after we made contact, exactly as promised, and evaluated the project and gave us a solid quote, all within half an hour. They really know their stuff. We ended up getting a battery rather than a generator, and they don't yet offer batteries, but if we had gone with the generator we definitely would have hired them. I have never written a review for a company I did not hire, but this company was truly professional. They were transparent, completely honest, straightforward, and such a pleasure to work with. They followed up promptly after their visit, always exactly as promised, gave us the information we needed to make our decision, answered every single one of our questions immediately, and never pressured us. Even when we decided on the battery rather than the generator, they thanked us for the opportunity to present themselves. Complete and total professionals, all the way."

"I recently had the pleasure of working with Brian from Hamilton Electric for a hot tub installation, and I couldn’t be more impressed with the experience. From start to finish, Brian demonstrated the highest level of professionalism, expertise, and attention to detail. The entire installation was handled seamlessly, with meticulous planning and execution to ensure everything was up to code and functioning perfectly. Brian was incredibly knowledgeable, answering all my questions with clarity and confidence. His workmanship was outstanding, and he took the time to ensure a clean and safe setup. Beyond the exceptional quality of work, the pricing was very reasonable, offering great value for the level of service provided. It’s rare to find an electrician who combines technical expertise with such professionalism and customer-focused service. I highly recommend Hamilton Electric for any electrical work—especially for specialized projects like hot tub installations."

"Overall experience was average. First day of installation was okay until I find out half of the house did not have power. Edgar came back the next day and explained the cause and fixed it with ease. Was getting push back about how everything was installed as it was and there shouldnâ t be any issues, well there was and he graciously came back and fixed the problem. I would definitely use this company in the future."

"Did a great job, even corrected some code violations that were present when we moved in. Installed multiple 110v, 230v single phase, 230v 3 phase and 480v 3phase circuits, wired a paint booth, Tumbler unit, overhead crane systems, and even did some repairs on a complicated piece of machinery that wasn’t working. Great guys work hard no excuses. They get the job done plain and simple. I had used them twice because they were that reliable."

Generator Install questions, answered by experts

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. 

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.

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.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

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.
