Whether caused by earthquakes, storms, wildfires, or simply the result of an overtaxed grid, power outages are unfortunately common in San Jose. And while brief power outages lasting only a few minutes are rarely more than a minor inconvenience, homeowners in Santa Clara County know that extended outages — potentially lasting for days — are occurring more and more frequently.
Fortunately, there’s a remarkably straightforward and effective solution: You simply need to have a backup generator installed for your home. With the right unit installed, you won’t notice any power disruption at all.
But the question is, who can you trust to install the generator? Which local electricians have the skills and expertise needed to connect your generator and ensure you’ll be protected? We’ll try to help by sharing a few of the most trusted generator installation experts below.

Choosing an Electrician for Generator Installation in San Jose: Things to Think About
Ratings and reviews are certainly helpful criteria to consider in your search for a generator installation contractor in San Jose, but they don’t represent the entire picture. In fact, there are several other things you’ll want to consider, such as:
- Licensing: You’ll always want to work with an electrician who is licensed in the State of California. This will not only help you avoid potential legal trouble, but it will also help ensure your electrician knows and follows current electrical codes.
- Insurance: Your electrician’s insurance policy helps to protect you in case anything goes wrong during the installation process. Just be sure that the contractor also carries workers’ compensation insurance in case any member of the contractor’s team is injured during the job.
- Certifications: Whenever possible, you’ll want to choose an electrician who is a Generac Certified Technician. This will help demonstrate that the electrician has undergone specialized training and demonstrated proficiency in installing Generac generators.
- Written Estimates: Professional electricians will always provide you with a written, itemized estimate before beginning work. This should lay out every expected part and service the job will require, along with their associated costs.
- Communication: Clear and efficient communication channels help ensure you’ll remain informed throughout the project and know what’s happening at every step in the process. So, avoid electricians who don’t respond to your calls, texts, or emails in a reasonable amount of time.
- Experience: You don’t want an electrician who is learning on the job; you want an electrician who not only has years of electrical experience but also experience installing backup home generators. Ideally, you’ll stick to contractors who have at least 10 years of experience or more.
- Financing: Because generator installation can represent a significant investment, it’s never a bad idea to choose an electrical contractor who offers financing options. A lot of electricians are unable to do so, but the leading choices in most markets usually can.
