Is your panel keeping up?
Planning an EV charger, heat pump or addition? Or dealing with recurring electrical problems? An assessment helps determine whether your panel needs replacement, more circuits or a service upgrade.
Adding an EV Charger or Generator
New equipment calls for a load assessment. An EV charger does not automatically require a service upgrade; we review available capacity and the proposed installation.
Burning Smell or Warm Panel
A warm panel or burning smell needs prompt attention. Do not open or work inside the panel. If there is smoke or fire, leave the area and contact emergency services.
Federal Pacific or Zinsco Panel
If your home has a Federal Pacific or Zinsco panel, arrange an assessment of its condition and replacement options. Confirm any insurer documentation requirements directly with your insurer.
Lights Dim When Appliances Run
Dimming lights can have several causes, including equipment starting loads or connection problems. We troubleshoot the cause before recommending a panel or service upgrade.
Planning a Renovation or Addition
Renovations and additions can require new circuits. We review the proposed equipment, circuit space and electrical load to plan an appropriate installation.
Breakers Keep Tripping
Recurring breaker trips can indicate an overload, a fault or another circuit problem. Have the cause investigated instead of assuming the panel is too small.
