About GoodnowAn outdated electrical panel is a safety risk and limits your home capacity. Here is what to watch for:
If breakers trip regularly, your panel may not have enough capacity for your electrical load.
Lights that dim or flicker when appliances run indicate an overloaded or failing panel.
Any burning smell from your panel box is a serious warning sign requiring immediate attention.
Fuse boxes in older homes should be upgraded to modern circuit breaker panels for safety and capacity.
EV chargers, hot tubs, HVAC systems — all require panel assessment before installation.
Adding square footage or a major remodel almost always requires a panel upgrade or expansion.
We inspect your current panel, assess your electrical load needs, and provide a no-obligation written quote.
We handle all permits. We plan the upgrade to minimize disruption to your home or business.
The new panel is installed, tested, and inspected. We restore power as quickly as possible.
