Expert Electrician Services in Tempe, Arizona

Much of central Tempe was built in the 1950s and 60s, when a 100-amp panel seemed like plenty. Decades of additions, garage conversions, and extra window AC units changed that. Now we find panels stuffed with tandem breakers, double-tapped lugs, and breakers that have never been tested since the house was new. When every slot is full and the bus bar shows heat marks, adding circuits is no longer safe. The real fix is a larger panel with room to grow, sized by a load calculation.

From July through September, afternoon storms roll across the Valley with serious lightning. A strike does not have to hit your house to hurt it. It can travel through utility lines, cable lines, and phone lines, frying whatever it reaches first. We see dead garage door openers, routers, and pool controllers every storm season. Whole-home surge protection, installed at the panel, blunts that spike before it reaches your devices. Point-of-use strips help too, but the panel device does the heavy lifting.

In 1950s and 60s Tempe homes, ungrounded two-prong outlets are still common. Many have been swapped for three-prong outlets without adding a ground, which looks safe but is not. The honest fixes are rewiring with a proper ground or adding GFCI protection where rewiring is not practical. Both are code-compliant paths when done right. During a safety inspection we open a sample of outlets, check what is actually behind them, and tell you which rooms need what.

The AC kicks on, the pool pump is running, someone starts the dryer, and click, half the house goes dark. Breakers age faster in hot garages, and Tempe garages get brutally hot. Heat makes an old breaker trip at lower loads than it should. Loose connections make it worse, since a loose lug runs hot and feeds the breaker even more heat. We test the load, check the connections with the power off, and replace breakers that no longer hold their rating.

Plenty of older Tempe homes still run a swamp cooler alongside the AC. The cooler circuit was sometimes added by a previous owner, with undersized wire, no disconnect, and connections hidden above a hallway. That wiring now sits in a blazing attic for months. A proper cooler circuit is a dedicated run, correctly sized, with a disconnect the next person can actually find. Simple, labeled, and built for the attic it lives in.

Pool equipment, landscape lighting transformers, and AC disconnects live their whole lives in the sun. UV breaks down insulation, heat cycles loosen lugs, and a summer storm finishes the job. We find cracked wire nuts, green-corroded terminals, and transformers mounted inches from a sprinkler. Outdoor work needs weather-tight fittings, sealed boxes, and GFCI protection near water. It costs more to do right than to do twice.
