Click Here to Call (888) 355-9624The story is similar in homes across the region. A family moves into a house built in the late 1970s. Everything works fine for the first year. The second summer, they notice the lights dim slightly when the central air kicks on. The third summer, a breaker starts tripping during heat waves. The fourth year, they buy an electric vehicle and realize the panel is full — there's no slot for the EV charger circuit. By the fifth year, an insurance review flags the panel brand on the door, and the policy renewal includes language about replacement.
None of the individual events are dramatic. None of them required an emergency call. But cumulatively, the panel that worked fine when the home was built has run out of room for the way the household actually lives now.

Typically six to eight hours during a one-day job in Dallas. We coordinate timing with you and the utility.
