Electrical Service Upgrades

Modern homes and businesses need more power—CJH Electrical delivers it safely, cleanly, and up to code.

What Is a Service Upgrade?

A service upgrade involves increasing the amount of electricity your home or building can safely receive from the utility company. If you have an older electrical system—or you're adding appliances, EV chargers, HVAC, or new square footage—it may be time to upgrade.

At CJH Electrical, we provide clean, code-compliant upgrades that prepare your property for today’s power needs and tomorrow’s growth.

Signs You May Need a Service Upgrade

Frequent breaker trips or fuse blowouts

Flickering or dimming lights when appliances run

Electrical panel over 30 years old

You still have a fuse box instead of a breaker panel

New renovations or additions planned

You're installing a heat pump, EV charger, or hot tub

Old Home? No Problem.

Many older homes still run on 60 or 100 amp service. CJH Electrical specializes in carefully upgrading these systems while respecting the architecture and preserving finishes wherever possible. We understand how to bring older structures up to code without unnecessary demolition or disruption.
