Generator Installation

Standby vs. portable generators: which is right for your home?

Standby generators install permanently outside your home, run on natural gas or propane, and switch on automatically within seconds of an outage. Portable units cost less up front but require manual setup and refueling. Our electricians help you weigh capacity, fuel access, and budget.

Our generator installation process

  • Load calculation & sizing so the unit matches your essential circuits
  • Automatic transfer switch installation and safe electrical tie-in
  • Permits, site prep, and inspection handled for you
  • Startup testing & safety checks before we leave

Why homeowners across the area choose Aliance

Licensed, insured electricians, transparent pricing, and financing options through our financing program. We also offer ongoing maintenance to keep your generator winter-ready.
