Common Questions

Standby Generators

Frequently Asked Questions

How does a standby generator work?

A standby generator is permanently installed outside your home and connected directly to your electrical panel. It monitors your power supply around the clock and automatically starts within seconds of detecting an outage — no manual startup, no extension cords, no fumbling in the dark. When utility power is restored it shuts itself off automatically and resets for the next outage.

What size generator do I need for my home?

The right size depends on the square footage of your home, the number of critical circuits you want covered, and whether you want partial or whole-home coverage. We offer free in-home assessments for homeowners throughout Lake, Porter and LaPorte Counties — we’ll evaluate your electrical load and recommend the right generator without overselling you on size you don’t need.

How long can a standby generator run during an outage?

As long as it has fuel. Most standby generators in Northwest Indiana run on natural gas or liquid propane connected directly to your existing fuel supply — so there’s no tank to refill and no running out of fuel during extended outages. Natural gas generators can run indefinitely as long as the gas supply is uninterrupted.

How often does a generator need maintenance?

Most manufacturers recommend annual maintenance including an oil and filter change, battery inspection, spark plug check, load test and full system inspection. Skipping maintenance is the number one reason generators fail to start during an outage. We offer maintenance plans for homeowners throughout Crown Point, Portage, Valparaiso, St. John, Dyer and all of NWI.

That means we install and repair using genuine Generac parts, our technicians are factory trained, and we can perform warranty repairs on your Generac generator. We also install and service Kohler and Briggs & Stratton standby systems throughout Lake, Porter and LaPorte Counties.
