MARICOPA COUNTY SERVICE UPGRADE PROS
Modernizing residential electrical capacity across Maricopa County is essential as households adopt electric vehicles, high-efficiency heat pumps, and solar battery storage. Older 100-amp and 125-amp service panels cannot safely sustain continuous summer cooling loads without dangerous overheating. Our licensed electrical contractors engineer, permit, and install 200-amp and 400-amp service entrances that deliver safe, lifelong power.

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.
