A professional evaluation can consider your existing service size, electrical load, panel condition, planned appliances, heating and cooling equipment, EV charging, and future renovations.

Is upgrading the panel the same as upgrading the electrical service?

Not always. A panel replacement may involve only the interior distribution equipment. A complete service upgrade can also include meter equipment, service conductors, grounding, exterior conduit, and utility coordination.

Can you upgrade a 100-amp service to 200 amps?

Yes. JA Electrical provides 100A-to-200A service upgrades when appropriate for the property and project requirements.

Do I need a service upgrade for an EV charger?

Not necessarily. Some properties have enough available capacity, while others may need load management, a panel improvement, or a complete service upgrade.

Can you install a 400-amp electrical service?

Yes. JA Electrical works with 400A and larger services when required. The correct capacity depends on the electrical load and property requirements.

How long does a service upgrade take?

The schedule depends on the existing system, project scope, utility coordination, permits, inspections, and equipment requirements. The property should be evaluated before providing a project timeline.

Do you provide commercial electrical services?

Yes. We provide troubleshooting, repairs, lighting, dedicated circuits, service upgrades, new electrical installations, remodeling, and single-phase or three-phase electrical work.
