Most residential generator installations in Lombard can be completed within 1-2 days. Commercial installations may take 2-5 days depending on the complexity. The process includes obtaining permits (which may take 1-2 weeks), site preparation, generator placement, fuel line connection, electrical wiring, and final testing. We handle all aspects of the installation to ensure a smooth, hassle-free experience for our customers.

The appropriate generator size depends on your specific power needs. For essential circuits (refrigerator, heating, some lighting), a 7-10kW generator is typically sufficient. For whole-house coverage in an average Lombard home, a 16-22kW generator is usually recommended. Larger homes with high power demands may need 22-38kW systems. Our technicians will perform a detailed load calculation to determine the right size for your specific requirements.

We recommend servicing your generator at least once per year for residential units and twice per year for commercial systems. Regular maintenance should include oil changes, filter replacements, battery testing, and general system inspection. After extended use during power outages, additional service may be necessary. Our maintenance programs include scheduled service visits to ensure your generator remains in optimal condition.
