Panel Upgrades & Service Changes — quick questions

How do I know I need a panel upgrade?
Common signs are breakers that trip, a panel that is full, flickering lights, or new equipment that needs more power than the old service can deliver. We do load calculations to confirm.
Do you pull the permit and coordinate with the utility?
Yes. We pull the electrical permit and coordinate with the utility for the service change; you do not have to manage that yourself.
How long does a panel change take?
Most residential panel changes are done in a day, with the power off for a few hours. We schedule it so the disruption is short.
Do you replace recalled or unsafe panels?
Yes. We remove panels with known safety issues and install a new panel sized to your current and planned loads.
