Pool, Panel & Outdoor Electrical Services in Phoenix, AZ
Casther Electric is a Phoenix electrical contractor (AZ ROC #311594) specializing in pool, spa, and outdoor work. Every job comes with a free estimate, a licensed & insured team, and a 12-month warranty on workmanship.
Pool Light Replacement
Burned-out incandescent or first-gen LED pool light? We replace with current-generation LED fixtures (Pentair IntelliBrite, Hayward ColorLogic, Jandy WaterColors). Color-changing models available. Same-day or next-day appointments for single-light jobs, including the niche check and the GFCI test.
Typical cost in Phoenix: $400 – $800 per light
Pool Electrical Installation
New-build pool electrical from the panel out — pump circuits, heater wiring, pool light feeds, automation low-voltage runs, water features, and the NEC Article 680 bonding grid. We coordinate with pool builders, inspectors, and the City of Phoenix permit office.
Typical project range in Arizona: $4,000 – $15,000+
Electrical Panel Upgrade
Adding a pool heater, a Tesla wall connector, or a new AC unit usually means your existing panel can’t keep up. We upgrade 100A → 200A, 200A → 400A, and install sub-panels for pool equipment pads and detached garages. We pull permits and handle SRP / APS coordination.
Typical AZ range: $4,000 – $8,000+ plus utility fees
EV Charger Installation
Level 2 home charging — Tesla Wall Connector, Universal J1772, ChargePoint Home Flex, and any 240V hardwired charger. Most installs start at $1,400 depending on panel distance and the load calc. We size the breaker correctly, run conduit cleanly, and pull the permit so your installation is inspected and code-compliant.
Starts at $1,400
Outdoor & Pergola Electrical
Pergolas, ramadas, outdoor kitchens, landscape lighting, low-voltage transformer feeds, post lights, and outdoor outlets. Everything weather-rated, GFCI-protected, and conduit-run for Phoenix heat and monsoon. We also re-wire damaged outdoor systems after lightning or rodent damage.

Service & Repair
GFCI keeps tripping? Pool light goes out every storm? Pump runs hot? Burnt smell at the panel? We diagnose and fix — straight to the root cause, not a band-aid. A $150 service-call fee covers the diagnosis and is credited toward the work if you approve the estimate.
