Repair or replace?
Should You Repair or Replace Your Square D Panel?
Repair is usually fine when...
- The panel is in good shape with no heat damage
- Breakers are available for your series
- You have room, or just need one or two new circuits
Replacement makes sense when...
- The panel is rusted, water-damaged or scorched
- You need more capacity for an EV, heat pump or addition
- The service is still 100 amps and your home has outgrown it

Frequently Asked Questions
Can I put a Homeline breaker in a QO panel?
No. QO and Homeline breakers are different sizes and designs. Each only fits its own panel series.
How do I tell if my panel is QO or Homeline?
Check the label inside the panel door. QO breakers are narrower and many show a small Visi-Trip window that turns red when tripped.
Why does my Square D AFCI breaker keep tripping?
It may be detecting a real wiring fault, a shared neutral, or a reaction to certain appliances. We test the circuit to find the cause.
Do you install new Square D panels?
Yes. We often install Square D panels during panel upgrades and when replacing Federal Pacific or Zinsco panels.
Can I add a surge protector to my Square D panel?
Yes. Square D makes surge devices that mount in your panel. We check grounding and install one in a short visit.
Do you replace Square D breakers the same day?
Usually, yes. We stock common QO and Homeline breakers on our trucks.
