People search for the problem or the upgrade, not the trade: 'EV charger installation', 'electrical panel upgrade', 'whole house generator', 'outlets not working'. A profile that lists 'electrical services' and nothing more gives Google very little reason to show it for any of them.
Homeowners are wary of electrical work in a way they aren't of, say, painting. They look for signs of a real, established business: a complete profile, clearly listed services, and reviews that say the work was safe and the site was left clean.
Commercial and residential searches often bring up different competitors. Tracking both kinds of keyword separately shows which market you're stronger in.
