What’s the difference between a whole-home standby generator and a portable generator?

A standby generator is permanently installed, connected through an automatic transfer switch, and typically runs on natural gas or propane. It starts automatically during an outage—no cords and no refueling in severe weather.

Can a generator power my sump pump?

In most homes, yes. We confirm your pump type and starting load, then design the backup power plan to include it where feasible.

Do I need an automatic transfer switch (ATS)?

Yes for a standby generator system. The ATS safely disconnects your home from the utility grid and switches your home to generator power automatically.

More about service in South Lyon, MI

Will a standby generator keep my furnace running during a power outage?

Often, yes. When properly sized and installed, a standby generator can power a furnace or boiler’s essential electrical components (controls and blower), helping you maintain heat during outages—one of the biggest benefits for Michigan winters.

Do I need permits and inspections?

In most municipalities, yes. Permits and inspections are common for generator installs. We take care of permitting and coordinate inspections.

How long does installation take?

On-site work is often completed in 1–3 days, depending on complexity. The full timeline depends on permitting and equipment lead times. We’ll set expectations up front and keep you updated throughout.
