Buying Guide
What to consider when choosing an air cooled standby generator:
- Power needs: Calculate your essential circuits and total load to match generator output with your home’s peak demand. Larger homes benefit from higher wattage and a robust transfer switch.
- Fuel type and availability: LP or natural gas compatibility affects fuel supply stability and running costs. Some models offer dual-fuel options for flexibility.
- Transfer switch: A premium automatic transfer switch (ATS) ensures fast, seamless power transfer. Check amperage compatibility with your service panel.
- Climate considerations: Cold-weather accessories (battery warmers, oil heaters) improve reliability in winter conditions; consider maintenance kits for routine care.
- Maintenance needs: All-in-one maintenance kits simplify service intervals; verify compatibility with your exact generator model and year.
- Noise and footprint: Heavier-duty models may be louder and bulkier. Consider placement in compliance with local codes and clearance requirements.
- Install and warranty: Some products imply professional installation is advisable to ensure code compliance and proper integration with your electrical system.
Frequently Asked Questions
- What is the typical lifespan of an air cooled standby generator?
– Properly maintained units often last many years, but lifespan depends on maintenance frequency and load patterns. - Do I need a maintenance kit for my standby generator?
