Common Questions
What El Dorado County Homeowners Ask About Backup Generators

  • How do I know what size generator my home actually needs?

    Generator sizing depends on your home's square footage, the number of appliances you want to keep running during an outage, and whether you have central HVAC or other high-draw systems. Our technicians assess your home's specific load requirements before recommending a system, so you're not paying for more capacity than you need. A properly sized Generac standby unit can power your essential circuits, including heating, air conditioning, refrigeration, and lighting, without straining the equipment or your budget.

  • What is a transfer switch and why is one required for generator installation?

    A transfer switch is a safety device that connects your standby generator to your home's electrical panel. When grid power goes out, it automatically switches your home's circuits over to the generator and disconnects from the utility line. This prevents dangerous back-feeding of electricity onto the grid, which can injure utility workers and damage your equipment. Smit's includes transfer switch installation as part of every whole house generator project, and our technicians ensure the setup meets local code requirements in El Dorado County.

  • Does a standby generator need regular maintenance even if it rarely runs?

    Yes. Generac standby generators run a brief self-test cycle weekly, but they still require periodic professional inspections to check oil levels, battery condition, coolant, and fuel system integrity. A generator that goes without maintenance can fail to start during an actual outage. Our Preferred Customer Maintenance Membership covers scheduled generator inspections and gives members priority scheduling and discounted service rates, making it easy to keep your backup power generator system in reliable shape throughout the year.

  • How long does a typical whole house generator installation take to complete?

    Most residential Generac installations in Diamond Springs and the surrounding El Dorado County area are completed in one to two days, depending on the complexity of the transfer switch setup and any electrical panel work required. If your panel needs an upgrade to support the new system, that can add time to the project. Our team will give you a clear timeline during the initial assessment so you know exactly what to expect before work begins.

  • Can Smit's repair a Generac generator that was installed by a different company?

    Yes. Our technicians provide home generator repair and maintenance on Generac systems regardless of who originally installed them. We diagnose issues with starting, fuel delivery, transfer switches, and control boards. If your existing unit is older or parts are no longer readily available, we'll be straightforward with you about whether a repair or a replacement makes more practical sense. You can reach us by call or text at (530) 622-8446 to describe the issue before scheduling a visit.

  • Are financing options available for a new generator installation?

    Yes, financing options are available through Smit's to help make a whole house generator installation more accessible. High-ticket system upgrades shouldn't have to wait until you've saved the full amount out of pocket, especially in an area like El Dorado County where outages can be frequent and prolonged. Ask our team about current financing programs when you call or book your appointment, and we'll walk you through what's available for your specific project.

  • Which communities does Smit's serve for generator installation and repair?

    We serve Diamond Springs, Placerville, El Dorado Hills, and the broader El Dorado County area, including zip codes 95762 in El Dorado Hills and 95672 in Rescue, with service extending to Folsom and surrounding communities. If you're unsure whether your address falls within our service area, give us a call or send a text and we'll confirm quickly.
