Do You Need a New Panel, More Electrical Capacity—or Both?

A new breaker panel does not automatically increase the amount of power available to your home. We assess the existing service and your plans before recommending a scope.

Panel Replacement

Replaces the interior breaker panel when its condition, available circuit space or equipment needs attention. If the existing service capacity is sufficient, an increase in amperage may not be needed.

Electrical Service Upgrade

Increases the home’s available service capacity when an assessment shows it is needed. A 100-to-200-amp upgrade can involve the panel, meter equipment, service entrance and utility coordination.

Planning a 100-to-200-amp upgrade? Explore our 200-amp service upgrade options.

Planning an EV charger or heat pump? Tell us what you’re adding. A load assessment helps determine whether your existing service can support it, whether load management is an option, or whether a capacity upgrade makes sense.

When Should You Have Your Electrical Panel Assessed?

Age alone does not determine the right solution. The equipment’s condition, circuit needs and your home’s electrical load all matter.

Repeated Breaker Trips

A tripping breaker can have several causes. We assess the circuit, connected equipment and panel before deciding whether replacement is the right solution.

Dimming or Flickering Lights

Tell us when it happens and which appliances are running. These symptoms need diagnosis; they do not establish that you need a larger service.

An Older or Unfamiliar Panel

If you have Federal Pacific, Zinsco, Pushmatic or fuse equipment, ask us to assess its condition and discuss replacement options.

EV Charging, Heat Pumps or Renovations

New equipment can change your home’s electrical demand. Planning ahead helps match the service capacity and circuits to the project.

What Does a Panel Replacement or Service Upgrade Cost?

Panel-only work and a service-capacity upgrade have different scopes. Use these price ranges to plan your project. Your home’s condition, capacity needs and required work determine the final proposal.

Service Upgrades

A service-capacity upgrade can include the interior panel, meter equipment, service entrance and grounding work. The equipment that needs replacement depends on the existing installation and utility company requirements.

100-amp main service replacement $4,700 – $5,700
100-amp → 200-amp upgrade $6,200 – $10,500
200-amp → 400-amp upgrade $14,000 – $24,995

Panel Replacements

Panel replacement focuses on the interior breaker panel when the existing service capacity is sufficient. Additional corrections may be needed after assessment; your proposal will identify any meter, grounding or exterior work.

100-amp panel replacement $1,350 – $2,100
200-amp panel replacement $2,195 – $3,495
Federal Pacific / Zinsco replacement $2,500 – $4,500

These are planning ranges, not a quote. Ask us to explain the panel, service entrance, permit and utility work included in your proposal before you approve the project.

Panel Replacement & Service Upgrade Questions

Does replacing a panel increase my home’s electrical capacity?

Not by itself. A panel replacement and a service-capacity upgrade are different scopes. Your existing service rating and a load assessment help determine what is needed.

Do I need a 200-amp upgrade for an EV charger?

Not every home does. Charger requirements, existing electrical loads and possible load-management options need to be assessed before recommending a service upgrade.

What affects the price?

The panel size, equipment condition, service entrance work, access, permit requirements and utility coordination can affect the scope. Request an itemized proposal for your home.

What permits and inspections should I plan for?

The requirements depend on your town and the scope of work. Before scheduling, ask which electrical permit and inspection apply, who will arrange them, and whether the utility company needs to coordinate a disconnect and reconnect. Confirm any planned power interruption and arrangements for essential equipment.

Will the power need to be turned off?

Panel and service work generally involves a planned power interruption. Confirm the expected duration, utility coordination and arrangements for essential equipment before scheduling.

Can you assess an older Federal Pacific, Zinsco or Pushmatic panel?

Tell us the brand if you know it. We can assess the equipment and discuss replacement options. Please do not remove the panel cover to identify it.

Can I combine panel work with an EV charger or generator?

Ask us to assess the projects together. Coordinating the scope can help with planning circuits, service capacity and scheduling, but the best approach depends on your home.
