"Sergio and his assistant installed an EV charger at my place, and they did an amazing job. I’m so glad I hired them. Their price was reasonable compared to other contractors. I highly recommend them and would definitely use their company again for any future jobs."

"HIGHLY RECOMMEND! Bill and Josh were great to work with. They were extremely responsive, professional, and accommodating. I was especially impressed with their electrical knowledge and ability to handle a complicated panel installation at my house. While installing the new panel, I happened to mentioned that I didn't have an exterior plug for my Christmas lights and they were able to install one exactly where I wanted it without any damage to the exterior of my house. There were a few other handyman issues around my house that they either had someone come out and take care of themselves or referred me to another capable company, which was extremely helpful considering I don't have a lot of time to research contractors. I am looking to get a Tesla in the near future and will absolutely be hiring Western Sunset to install the charger in my garage. You won't regret your decision to hire them for whatever electrical work you need done."

"The electrician was over an hour late for his appointment. Aside from that, the owner and his employee were very helpful at instaling the extra outlet and pointing out flaws in the electrical system in the house. Highly recommended."

Generator Install FAQs, answered by experts

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.

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.

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.
