Generac Generator FAQs (Charleston)
Are you a certified Generac dealer and installer in Charleston?
Yes. All Plumbing is a certified Generac dealer and installer serving Charleston and the Lowcountry. That means we’re trained to size, install, and register your unit correctly, and we can perform warranty-covered service using genuine Generac parts.
Why do you recommend Generac for Charleston and Lowcountry homes?
Generac is the #1 residential backup generator brand in the country, and it’s built for exactly what Charleston homeowners need — automatic startup within seconds of an outage, whole-home coverage, and quiet, reliable operation. After installing hundreds of units across South Carolina, it’s the brand we trust most for low-maintenance peace of mind.
Are Generac generators good for hurricane-prone, coastal areas like Charleston?
They’re an excellent fit. In the Lowcountry, outages often come with hurricanes and tropical storms that can last for days, and Generac’s automatic transfer switch restores power without you lifting a finger — keeping your sump pump, well pump, and refrigerator running when it matters most. For low-lying and coastal homes, that automatic protection is the whole point.
What fuel does a Generac generator run on?
Generac standby units run on natural gas or propane, depending on what’s available at your property. We’ll recommend the right fuel and handle the connection — including any gas line work your generator needs to run safely and to code.
What warranty comes with a Generac, and can you service it locally?
Every new Generac includes a standard 5-year limited warranty, with extended coverage available at install. As a certified installer, we handle warranty registration, covered repairs with OEM parts, and diagnostics for all Generac controller systems — so you’re supported right here in Charleston, not routed to an out-of-state call center.
Do you repair Generac generators you didn’t install?
Yes. We service and repair Generac units whether we installed them or not. If your generator is throwing a fault code, won’t start, or hasn’t been serviced in years, see our generator repair & service.
Can I monitor my Generac remotely?
Yes — most current Generac models include Wi-Fi Mobile Link monitoring, so you can check your generator’s status and get alerts from your phone. It’s one of the features that sets Generac apart from other brands, and we’ll set it up during installation.
How much does a Generac generator cost in Charleston?
It depends on the model, size, and your home’s fuel and electrical setup. We give you a clear, upfront, by-the-job price after a free on-site consultation — no work starts until you approve it. See our whole-house generator installation page for how the process and sizing work.
