If any of these apply to you, a whole-home generator is a smart step:
Frequent power outages throughout the year
Risk of food spoilage, heating loss, or frozen pipes
Work from home or rely on Wi-Fi connection
Medical devices or sensitive health concerns
Critical systems like sump pumps or well water
Keep security systems and lighting on
Want to power the entire home, not just a few essentials
