Our approach
Upgrading your service box through an electrical panel upgrade in Peoria AZ ensures your home can safely handle high-draw central air conditioners, electric vehicle chargers, and modern electric kitchen appliances. Many homes built before 1990 feature 100-amp or 125-amp panels that overheat during extreme Arizona summers. We design, permit, and install code-compliant 200-amp and 400-amp panels that protect your household.
We are a direct electrical contractor, not a referral service. The technician who quotes your electrical panel upgrade is the one who carries it out, and the licence number on your invoice is ours. That matters when something needs revisiting under warranty.
Every job starts with diagnosis you can see for yourself — camera footage, a pressure reading, or the failed part in hand — and a written flat-rate price before anything is dismantled.
How we work
Every conductor terminal is torqued to exact manufacturer specifications to avoid thermal loosening under high summer electrical currents.
Local failure modes
These are the failures we actually see here, driven by the local housing stock, water, and climate rather than a generic list.
FPE Stab-Lok and Zinsco panels installed in older Peoria homes suffer proven failure rates where breakers lock closed during short circuits.
What we do
We pull a city permit, replace the hazardous box with a modern copper-bus Square D or Siemens enclosure, and install AFCI protection.
Homes with older 100A service panels exceed safe capacity when dual air conditioning compressors and pool pumps cycle on simultaneously.
What we do
Our crew performs a formal NEC Article 220 load calculation, coordinates a utility service drop upgrade, and installs a high-capacity 200A panel.
Adding a 50-amp Level 2 charger circuit to a crowded panel forces improper tandem breakers or risky double-tapped connections.
What we do
We install a spacious 40-circuit panel with dedicated capacity for EV supply equipment, whole-home surge, and future home additions.

How it works
The same sequence on every job, so you always know what happens next.
Speak directly with an experienced electrical technician who provides immediate safety guidance and estimates arrival time.
Our technicians arrive in vans carrying standard breakers, copper conductors, and precision diagnostic tools ready for work.
We inspect circuit loads and connections with thermal cameras and digital multimeters, providing a clear written repair quote.
We complete the electrical work according to NEC standards, test each circuit under load, and verify full operational safety.
On the job
Timings are realistic averages from completed jobs, not best-case estimates.
We inspect existing square footage, HVAC loads, and appliances to determine exact amperage requirements.
We submit blueprints to the City of Peoria and schedule the disconnect window with APS or SRP.
Our crew installs the new meter-main combo, ground rods, cold-water bonding, and branch breakers.
The city building inspector reviews the work, passes the installation, and the utility re-energizes power.
Warning signs
Any one of these warrants a call today rather than next week.
Main circuit breaker feels warm or hot during summer afternoons
Breakers trip frequently when vacuuming or using the microwave with AC running
Presence of obsolete brands like Zinsco, GTE Sylvania, or Federal Pacific
Rust, corrosion, or oxidation forming inside the breaker box enclosure
Lack of open breaker slots to install EV chargers, solar, or pool equipment
Equipment
Owned outright and operated by our own technicians, not subcontracted in.
Finished work
The finished installation features neat wire routing, whole-home surge suppression, and clear directory labeling for every household room.

Reviews
Rated 4.9 out of 5 across 184 customer reviews.
Upgraded our 200A main service panel and installed a hardwired Level 2 Tesla EV charger in the garage. Clean conduit bending, filed the City of Peoria permit promptly, and passed inspection without an issue.
Our main AC breaker kept tripping on a 112-degree afternoon. The technician arrived in 35 minutes, found severe thermal degradation on the breaker bus bar, and replaced the breaker assembly safely.
Installed a whole-home surge protection device and added dedicated 20-amp circuits for our backyard pool pump equipment. Explained voltage spike ratings clearly and gave a fair flat-rate price.
Remediated 1970s aluminum wiring in our branch circuits using AlumiConn connectors. Very meticulous work, checked every outlet switch box, and provided full documentation for our home insurance company.
