GLENDALE PANEL UPGRADE PROS
Upgrading your residential service panel in Glendale 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 panels that protect your property and satisfy home insurance standards.

Glendale conditions
Specific to this area rather than a generic list — these come from jobs completed on these streets.
Many mid-century Glendale homes still contain obsolete panels with high failure rates that fail to trip during short circuits.
What we do
We coordinate with the utility to replace hazardous boxes with modern copper-bus Square D or Siemens panels.
Homes with older 100A panels exceed safe capacity when dual air conditioning compressors and pool pumps run together.
What we do
We perform formal NEC load calculations, upsize service conductors, and install high-capacity 200A panels.
Adding a 50-amp Level 2 charger circuit to a crowded panel forces risky tandem breakers or double-tapped connections.
What we do
We install a spacious 40-circuit panel with dedicated capacity for EV supply equipment and future home additions.

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.
