Electrical Panel Upgrade · Statewide · Answered 24/7
100 amp to 200 amp service upgrades, breaker box replacement and sub panels — so the house can carry an EV charger, a heat pump and a modern kitchen at the same time.

Power disconnect and reconnect are scheduled with the utility, and inspection is arranged for you.
Typical residential panel swaps are a one-day job. Power is off for part of it and we tell you the window in advance.

Most of the day for a straight changeout. We schedule it so the outage lands in daylight and let you know the window ahead of time.
If you are adding an EV charger, an electric range, a hot tub or a heat pump to a 100 amp service, usually yes. We run the load calculation and tell you honestly if 100 amps is still fine.
Both have a documented history of breakers that fail to trip on a fault. Replacement is the standard recommendation, and it is one of the most common jobs we do in older Oklahoma neighborhoods.
