What Size Generator Do I Need for My North Idaho Home?

Most North Idaho homes need a standby generator between 10 and 24 kW. If you want to keep the essentials running, like your furnace, well pump, refrigerator, and some lights, a 10 to 14 kW unit is often enough. If you want whole home backup that runs almost everything at once, most homes land in the 16 to 22 kW range. The right size depends on your home and what you want to power, and we are glad to help you figure it out.

How generator sizing works

Sizing is not a guess. We look at what you want to run during an outage, add up the power those items use, and size the generator to handle it with room to spare. Motors like your well pump, furnace blower, and air conditioner draw extra power the moment they start, so we plan for that starting load. We also add a margin for safety and for anything you may add later. The result is a generator that starts your loads cleanly and does not strain during a storm.

Essentials backup or whole home

There are two common ways to go. Essentials backup keeps your critical circuits running, which is a good fit if you mainly want heat, water, and a working fridge during a North Idaho winter outage. Whole home backup powers your entire panel so life feels normal, including larger loads like an electric range, air conditioning, or an EV charger. We help you weigh cost against comfort and pick the size that fits.

What affects the size you need

A few things move the number up or down. The square footage of your home, whether you heat with electricity or gas, whether you have air conditioning, well pump horsepower, and whether you plan to add an EV charger or hot tub all matter. Fuel choice matters too, since natural gas and propane units are sized a little differently. We take all of it into account.

We size and install it right

We handle the electrical side of your standby generator from sizing to the final inspection. That includes the transfer switch or interlock, the wiring, the permit, and the inspection, so your generator and the utility are never connected at the same time and there is no dangerous backfeed. We serve Coeur d'Alene, Hayden, Post Falls, Rathdrum, Liberty Lake, and Spokane Valley. Call or text 208-352-0662, and get set up before the first big storm.
