🧭 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.
