What size generator do I need?

It depends on what you want to keep running. Essentials only (fridge, lights, well pump, a few outlets) can run on a 10–14kW unit. Whole-home with central AC usually needs 22kW or more. We do a free on-site load calc instead of guessing.

Is the transfer-switch inspection really free?

Yes — completely free, no obligation, no upsell pressure. If we find something unsafe we'll explain it and quote the fix, but you're never required to use us.

How often does a standby generator need service?

Once a year minimum. Annual service includes oil, filter, battery check, exercise cycle, and a load test. Skipping it voids most manufacturer warranties and is the #1 reason generators fail to start when needed.

What brands do you install?

Generac, Kohler, and Briggs & Stratton primarily. We'll recommend based on what's serviceable locally and what carries the warranty terms that matter for your install.

Yes — and we pull it. Installation requires both an electrical and a gas/mechanical permit in most jurisdictions. We handle both and the inspection.
