🧭 Key Buying Considerations

  • Fuel type: Natural gas is most common; propane offers higher output but requires a tank.

  • Sizing: 18–24 kW covers most modern homes; larger homes or electric heat may need 26–30 kW.

  • Transfer switch type: Whole‑home vs. load‑shedding options.

  • Noise level: Important in suburban neighborhoods.

  • Maintenance & service availability: Generac has the largest service network; Kohler and Cummins offer higher durability.

⚠️ Risks & Trade‑Offs to Consider

  • Installation costs can exceed the generator price (often $3,000–$7,000).

  • Natural gas supply limitations may reduce output vs. propane.

  • Noise ordinances in some towns restrict placement.

  • Transfer switch compatibility varies by model—always confirm before purchase.

  • Maintenance contracts are strongly recommended for long‑term reliability.
