Common questions

Before you schedule.

Does every older panel need to be replaced?

No. Age alone does not decide the answer. Condition, capacity, equipment type and future plans all matter. We evaluate the existing system before recommending replacement.

Can a panel upgrade prepare my home for an EV charger?

Yes. EV charging is one of the loads we consider when reviewing panel capacity, available breaker space and the installation path.

Do you handle service changes as well as panel replacements?

Yes. The exact scope depends on the existing service, utility connection and project requirements.
