Frequently Asked Questions

  • What generator brands does Sergeant Generators work on besides Generac?

    We service all makes and models, including Briggs & Stratton and Kohler, even if we didn't install them originally. As an authorized Generac dealer with 23 years of industry experience, we carry parts and diagnostic tools for multiple manufacturers. This means faster repairs regardless of what brand powers your home.
  • How do Michigan storms affect generator maintenance schedules?

    Michigan's ice storms and summer thunderstorms create peak demand periods when generator failures happen most. Pre-season maintenance in early spring and late fall catches issues before outages strike. Oil degrades faster in cold starts, and moisture from freeze-thaw cycles corrodes connections, making twice-yearly service critical here.
  • What's included in a generator tune-up and inspection?

    Oil changes, filter replacements, battery tests, and full system diagnostics identify problems before they cause failure during outages. We inspect fuel lines, check transfer switch operation, and test the generator under load to confirm it performs when needed. This prevents breakdowns during extended power loss.
  • Why does proper generator sizing matter for whole-home backup?

    Undersized units struggle during simultaneous high-draw loads like well pumps, HVAC systems, and water heaters, causing voltage drops that damage electronics. Oversized systems waste fuel and cost more upfront. We calculate your actual power needs based on essential circuits and usage patterns to match the right capacity.
  • Can you install a generator if one wasn't planned during home construction?

    Retrofit installations require running gas lines, placing concrete pads, and installing transfer switches after walls are closed. Pre-wiring during construction avoids costly wall penetrations and allows optimal placement near service panels. Coordinating with builders early prevents accessibility and code compliance issues later.
  • What's the difference between portable generator setup and standby installation?

    Portable setups require manual starting, extension cords, and careful load management to prevent backfeed into utility lines. Standby systems use automatic transfer switches that detect outages and start within seconds, powering hardwired circuits safely. Standby units also run on natural gas or propane instead of stored gasoline.
  • When should you replace a generator instead of repairing it?

    Generators nearing 15-20 years old with frequent failures or major component damage like seized engines often cost more to repair than replace. Newer Generac models offer better fuel efficiency, quieter operation, and improved load management. We assess repair history and remaining lifespan to recommend the most cost-effective option.
  • What does the $100 referral program at Sergeant Generators cover?

    You receive $100 when someone you refer completes a generator installation or major service. The referred customer also benefits from our competitive pricing and veteran-owned business values. This applies to new installations, replacements, and commercial generator projects.
  • How does being an authorized Generac dealer affect warranty support?

    Authorized dealers access manufacturer-backed warranties, direct parts support, and technical resources unavailable to independent installers. If warranty issues arise, we handle claims directly with Generac rather than requiring you to navigate manufacturer channels. This speeds resolution and ensures parts availability.
  • What makes generator diagnostics different from routine maintenance?

    Diagnostics use load testing and advanced meters to identify hidden issues like voltage irregularities, weak batteries, or failing transfer switches that don't show up during idle checks. Maintenance focuses on consumables like oil and filters. Diagnostics are ideal for older systems or before storm season to confirm actual performance capacity.
  • Why does Sergeant Generators offer 24/7 emergency service?

    Power outages don't follow business hours, and generator failures during multi-day storms leave homes without heat, refrigeration, or medical equipment power. Immediate response restores safety and comfort when you need it most. Our owner-operator model means the same experienced technician responds to both routine and emergency calls.
  • What's the $250 military and veteran discount applied to?

    The discount applies to new generator installations for active military members and veterans. This reduces upfront costs on whole-home standby systems, making reliable backup power more accessible. The discount works with manufacturer warranties and our standard installation service, and it's available across all service areas.
