  • Noise and footprint: Consider outdoor placement and noise levels, especially in neighborhoods with strict regulations or proximity to living spaces.
  • Warranty and service network: A solid warranty and accessible service network reduce long-term ownership risk and downtime.
  • Ease of installation: Professional installation ensures proper wiring, venting, and code compliance, reducing safety concerns and insurance issues.
  • Compatibility with accessories: Check for compatible filters, ignition switches, and controllers to simplify maintenance and customization.
  • Maintenance intervals: Regular fuel system checks, oil changes, and air/cabin air filtration maintenance extend generator life and reliability.
