Extreme weather events and an overburdened electrical grid are becoming more common—and more disruptive. A permanently installed home backup generator keeps your home protected during unexpected and prolonged outages by automatically powering your essential appliances, even when the grid goes down. These systems run on natural gas and are installed outside your home, wired directly into your electrical panel. When the power goes out, your generator steps in—keeping lights on, the A/C running, and your family safe and comfortable until the utility company restores service. Cavanagh Electric installs dependable, high-performance whole-home generator systems designed to keep your home running smoothly through any outage.
Generators come in various sizes, from compact units that power only your essentials (like your refrigerator, HVAC, and sump pump), to whole-home systems that let you ride out an outage without skipping a beat. Ask yourself: Do you want to be completely unaffected during an outage, or simply maintain comfort and avoid losing food, heating, or cooling? Cavanagh Electric helps you find the right fit—whether you're powering just the basics or every outlet in the house.
We install systems that can handle:
In addition to helping you size the right generator, we also offer different installation options depending on your budget and preferences.
Whether you're at work, away on vacation, or just want the peace of mind that comes with full automation, Cavanagh Electric has you covered.
A backup generator is a smart investment in your safety, comfort, and peace of mind. But it's not a DIY job—proper installation requires experience and licensing. That's where Cavanagh Electric comes in. Our licensed electricians will work with you to customize the right backup power solution for your home and budget—so you're ready for whatever comes next. Call today and talk to one of our experts. Stay safe, stay powered, and trust Cavanagh Electric to get the job done right.
