Repair vs. upgrade considerations
Many electrical issues are isolated — a failed switch, a loose neutral, a worn outlet. Others signal a larger capacity or safety issue, such as an undersized panel, shared neutrals, or aging cloth or aluminum wiring.
If your home is adding heavy loads (EV charger, heat pump, induction range, hot tub, ADU), an electrician may recommend a load calculation before adding circuits. Older 100-amp services often need an upgrade before a major addition.
