Panel Repair, Upgrades and Replacement for Gilbert Homes

The problem homeowners are really describing

The panel is the one part of the electrical system almost nobody looks at until it forces the issue — a breaker that won't stay on, a warm panel cover, a burning smell at the garage wall, or an electrician for a new AC saying "your service can't carry that." What sounds like one dead breaker is often a panel that ran out of room and margin years ago and is only now being asked to do more.

Why panels reach the end of the road

Three things push a panel from "fine" to "replace it." First, capacity: a 100-amp service sized in 1996 for a gas range and a single AC has no headroom for a heat pump conversion plus a Level 2 EV charger. Second, obsolescence: certain brands installed in older builds — Federal Pacific and Zinsco among them — have a documented record of breakers that fail to trip under a fault, which defeats the panel's entire purpose. Third, wear: bus bars corrode, breaker contacts pit, and aluminum feeder lugs loosen through two decades of Arizona heat cycling until the connection runs hot. A repair fixes one of those; it can't fix a panel that's all three.

When a panel upgrade is the wrong call

Not every full-looking panel needs replacing. If your service is a modern 150- or 200-amp panel and it's simply out of physical spaces, a sub-panel or a tandem breaker approved for that panel can add circuits for far less than a service upgrade. If one breaker fails and the rest of the panel is a current, supported brand in good condition, that's a breaker replacement, not a new service. And if you're not adding major load — no EV charger, no pool, no casita — a healthy 125-amp panel may carry your home for years. We'll tell you when the cheaper path is the right one.

The panel services grouped here

When a specific component has failed, that's electrical panel repair. When the service is too small for your loads, an electrical panel upgrade raises capacity, and a full electrical panel replacement swaps out an unsafe or obsolete box for a new, code-current one. Because Arizona monsoon storms and utility switching send surges down the service, many panel jobs pair with whole-home surge protection mounted right at the panel. If your real problem is a breaker that keeps tripping rather than the panel itself, start with circuit breaker repair.

How a panel upgrade or replacement goes

1. Load calculation and inspection

   We measure your real and planned loads and inspect the existing service, so the new panel is sized for the house you'll have, not just the one you have.

2. Permit and utility coordination

   We pull the Town of Gilbert permit and schedule the utility disconnect and reconnect so the changeover happens on a set day.

3. Changeover

   The old panel comes out, the new service, grounding and breakers go in, and circuits are labeled clearly for once.

4. Inspection and power-up

   The work is inspected, the meter is reset, and we verify every circuit before we hand it back.

What you can check before you call

• Read the brand and main breaker rating (100A, 150A, 200A) off the panel label — it's usually inside the door.
• Note whether spaces are full or breakers are doubled up with two wires under one screw.
• Feel the cover for warmth and listen for buzzing (from a safe distance — don't open the box).
• List what you plan to add: EV charger, heat pump, pool, casita, hot tub. That drives the size.

Local detail: Gilbert panels and permits

Gilbert's big growth waves — the late-'90s Val Vista Lakes and Neely Farms builds, the 2000s Power Ranch and Morrison Ranch expansions — put in a lot of 125- and 150-amp services that were generous then and tight now that the same homes are adding EV chargers and heat pumps. Panel replacements and service upgrades in Gilbert are permitted through the Town of Gilbert Development Services building division, and SRP or APS (depending on your grid) handles the meter disconnect. We manage both so you're not the one on hold with the utility.
