Got questions about installing or maintaining a Generac generator? Our highly trained team is here to provide expert answers—whether it’s a quick question or a detailed discussion. Let’s find the perfect solution for you!
Let's Get Started

Get the Unbeatable Protection of a Generac Generator!

When the power goes out, your Generac standby generator turns on automatically—usually within seconds—so your home stays safe and comfortable. That means your heat or A/C, refrigerator, sump pump, Wi-Fi, lights, and essential systems can keep running without you doing anything.

Unlike portable generators, a standby generator is permanently installed, starts and stops on its own, and runs on your home’s natural gas or propane—so there’s no refueling, no extension cords, and no scrambling during a storm.

Choose the Right Level of Backup Power

Generac standby generators range from 10–28kW, supporting homes from about 1,000 sq. ft. to 6,000+ sq. ft. depending on what you want to power. We’ll review your needs and design the right solution for your home and budget:

    • Essential Power Coverage – Keeps the most important circuits running (like heat, fridge, sump pump, and some lights).

    • Whole-Home Backup – Powers most or all of your home for the most seamless “business as usual” experience.

    • Managed Whole-Home Backup – A flexible middle-ground that uses Generac load management to deliver near whole-home coverage with a smaller generator—balancing comfort, performance, and cost.

We Handle Everything

We manage the entire process for you, making generator installation simple and stress-free.

    • Financing options available (if needed) — terms from 12 months up to 12 years.
    • Right-size your generator based on your home and priorities.
    • Determine the best generator location for safety, performance, code compliance, and ease of service.
    • Handle permits and utility/gas coordination.
    • Professional installation of the generator, transfer switch, and all connections.
    • Full testing and inspection support so it’s ready for real outages.
    • Ongoing service and maintenance, with optional remote monitoring and annual tune-ups using genuine Generac parts.

Why Choose a Generac Standby Generator

  • Automatic operation – Your generator senses an outage and turns on automatically—then shuts off when utility power returns. You’re protected whether you’re home, at work, or away on vacation.

  • No refueling – It runs on your home’s existing natural gas or propane supply, so you’re not dealing with gas cans, refills, or long lines during storm season.

  • Safe, direct power – A professionally installed transfer switch feeds power straight into your electrical panel, eliminating extension cords and reducing the risk of unsafe backfeeding.

  • Strong warranty options – Choose 5-, 7-, or 10-year coverage options for added confidence, with support available if your generator needs service.

  • Added home value – Standby power is a major selling point for buyers who want reliability, comfort, and protection for essential systems during outages.
