Whole-House Generator Decisions: When to Repair & When to Upgrade

Generators don’t all need the same attention. Knowing the type of issues your system shows helps you choose whether a repair will suffice or a full upgrade is smarter.

Repair: Ideal if your generator only has a handful of isolated issues, like worn components or minor electrical glitches, that can be fixed quickly to restore your system’s full power.

Upgrade: Best when your generator can’t keep up with peak household demands, running multiple high-powered appliances, or frequent power interruptions.

We turn complex choices into clear actions to help you decide the most reasonable next step.
