Breaker Panel Upgrades in Surprise & the West Valley

If your home still has a 100-amp panel, federal Pacific breakers, or a fuse box, you're running on infrastructure designed for 1970s electrical loads — before EV chargers, heat pumps, and smart home systems existed. Mason Electric upgrades residential panels throughout Surprise, Goodyear, and Peoria with code-compliant Square D, Siemens, and Eaton panels rated for modern usage.

When You Need a Panel Upgrade

• Breakers that trip repeatedly under normal use
• Lights that flicker when large appliances kick on
• A panel that feels warm or makes buzzing sounds
• No room to add new circuits for an EV charger or hot tub
• A home built before 2000 with the original panel still in place
• Fuse boxes (any home still running fuses needs an upgrade)

Panel Upgrade Services

100A to 200A Service Upgrade (Most Common)

Most Surprise and Goodyear homes built before 2000 have 100-amp service. A 200-amp upgrade provides the capacity needed for EV chargers (typically 48A dedicated circuit), modern HVAC systems, in-home offices, and additional kitchen circuits.

Federal Pacific & Zinsco Panel Replacement

Federal Pacific Electric (FPE) Stab-Lok panels and Zinsco panels are recalled and considered fire hazards. Their breakers are documented to fail to trip during overloads. If your home has either, replacement is the only safe resolution.

Sub-Panel Installation

When a garage, workshop, pool house, or addition needs its own circuits but your main panel is full, a sub-panel is the solution.

Panel Issue	Recommended Action	Typical Cost Range
100A panel, need more capacity	200A service upgrade	$1,800–$2,800
Federal Pacific / Zinsco panel	Full panel replacement	$1,600–$2,500
Fuse box still in use	Replace with breaker panel	$1,400–$2,200
Main panel full, need more circuits	Sub-panel installation	$800–$1,600

How a Panel Upgrade Works

• Assessment & Permit — We assess your current panel, load requirements, and coordinate permitting with the city and utility company (APS or SRP).
• Utility Coordination & Installation — We schedule a brief utility shutoff, pull the meter, and install the new panel. Existing circuits are transferred and labeled.
• Inspection & Restore — A city inspector signs off on the work. We restore power and walk you through your new panel.

Need an EV charger installation too? We can assess your panel and charger needs in a single visit.
