Warning Signs

Signs Your Panel May Already Be Struggling

Before you even run the calculator, some homes show obvious signs that their electrical panel is maxed out. If you’re experiencing any of these, call us today:

Lights dim when AC kicks on A classic sign your panel is being pushed to its limits during peak demand.
Breakers trip frequently Breakers tripping often means circuits are overloaded and need attention.
Warm or buzzing panel Heat or buzzing from your breaker box is a serious warning sign — call us immediately.
Screw-in fuses instead of breakers If your panel still has fuses, you need an upgrade today. This is a safety issue.
No room for new breakers If your panel is physically full, you need a subpanel or full upgrade before adding anything new.
