Buying Guide: Key Purchase Considerations for Whole-Home Generators
What size generator do you need? Start with your home’s square footage, peak electrical load, and essential circuits. A larger home or higher appliance load requires 14kW or more, especially if you want to run central air and multiple rooms simultaneously.
What about fuel type? Natural gas and propane have different availability and costs. Dual-fuel options offer flexibility, but require a professional assessment for safe installation and venting.
How important is remote monitoring? Wi‑Fi connected models let you track status, maintenance alerts, and run diagnostics from anywhere, reducing downtime risk during outages.
What about transfer switches? A 100 Amp switch covers most homes, while larger residences may need 200 Amp service to support higher loads. Ensure the switch matches your electrical panel and local code requirements.
Do you need quiet operation? Some models emphasize low-tone mufflers and quieter tests, which helps in residential neighborhoods with noise restrictions.
Installation considerations: A licensed professional should assess site clearance, service panel compatibility, exhaust routing, and permitting. Proper ventilation, setback distances, and weatherproof enclosures impact long-term reliability.
