Glendale’s electrical needs are shaped by two things: its housing stock and its climate. The city includes a mix of mid-century homes in areas like the Catlin Court and Old Towne historic districts, along with decades of newer residential construction spreading west and north. Older homes in these historic pockets sometimes still carry original wiring, undersized panels, or aluminum branch circuits that weren’t built for today’s electrical loads, while newer homes more commonly need EV charger circuits, panel additions, or smart-home wiring.

Across all of it, Arizona’s summer heat is the real stress test. With air conditioning systems running for months at high output, panels and circuits in Glendale homes take on sustained heavy loads that can expose weak breakers, loose connections, or aging equipment, a common driver of the panel upgrade and repair calls we get from Glendale homeowners.

Electrical permits for work in Glendale are issued through the City of Glendale Building Safety, Codes & Services department, and all work must be performed by a contractor licensed with the Arizona Registrar of Contractors. Glendale’s electric utility service is split by location: Arizona Public Service (APS) serves the northern part of the city, while Salt River Project (SRP) serves the southern part. We coordinate directly with the correct utility for panel upgrades or new service connections.
