Michigan Has Some of the Longest Power Outages in the Country.
Between summer thunderstorms, ice storms, and high-wind events, the average Macomb or Oakland County home loses power multiple times a year — sometimes for days. The replacement cost in spoiled groceries, hotel nights, sump-pump failures, and lost work hours adds up fast. A Generac standby system pays itself back over the lifetime of your home.
The #1 Selling Brand of Home Standby Generators
Generac invented the home standby generator category and has built the most trusted, most installed backup power systems in North America for over 60 years.
Power On in Seconds
When the utility cuts out, your Generac detects it and starts automatically — your home is back online within 10 seconds, every time.
Runs On Your Existing Gas
Generac standby units run on natural gas or liquid propane from your home's existing supply. No refueling. As long as the utility flows, your generator runs.
Whole-Home Coverage
Heat, AC, refrigerator, sump pump, lights, Wi-Fi, medical equipment. Generac models from 10 to 26 kW are sized to cover everything from essentials to the entire home.
5-Year Limited Warranty
Every new Generac Guardian Series unit comes with a 5-year limited warranty. As an Authorized Service Dealer, NEXT handles warranty repairs in-house — fast, factory-direct.
Which Generac Is Right for Your Home?
Generac home standby generators are sized in kilowatts (kW). The right unit depends on your home's size, the appliances you want running during an outage, and your fuel source. NEXT performs a full load calculation as part of every free estimate.
Below is a general guide to help you understand the Guardian Series. Most Metro Detroit homes land in the 18 kW to 24 kW range for full whole-home coverage. We confirm exact sizing on-site as part of your free estimate.
