"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."

Customers say: True professional

"We needed work done involving three different trades and were hoping to find one company that could complete all aspects of the job. The work included sheetrock replacement (including texturing to be paint-ready), laminate flooring & padding installation, and bath vanity install & connect water lines. We received estimates from four different companies and chose Armando Espinoza Villa Handyman. Armando came over to see and discuss the job and provided an estimate later that day. He has a calm, low key demeanor and did a good job of listening to what we needed done. His pricing was fair, and he has experience in all the areas involved in our project. He also has many very good reviews on Angi, which was a factor in hiring him. Additionally, we Googled his company to see photos of his work. Armando completed all of the work on our house in just over two days. His work looks professional and we're very pleased with how it turned out. We'd hire him again. We've included photos."

"We hired proper power electric to update lighting and switches in our home. Forest and foster showed up on time. They were professional and in sync with each other. We added recessed lighting, fan ,and outdoor lights to our new home. Forest made suggestion to add another switch down the hallway to make it easier to turn off lights when going to the room. Both were knowledgeable, helpful and very friendly. They even helped my neighbor with their solar panel system. We had a great experience and will definitely hire again."

"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

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.

Most homeowners won't be able to claim a home generator as a tax write-off. However, a whole-house generator may be tax-deductible in certain situations depending on its purpose. For instance, if it's needed to power essential medical equipment, it may qualify as a medical expense deduction. Also, in some cases, businesses can deduct a generator as a business expense if it supports operations. Always consult a tax professional to determine eligibility based on your specific circumstances and the applicable IRS regulations.

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

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.
