If your breaker keeps tripping, your lights dim when the AC kicks on, or you quietly wonder every night whether something inside your walls is a fire waiting to happen — your electrical panel is telling you something. At FHR Electric, we specialize in Electrical Panel Upgrades for homeowners and business owners across Scottsdale, North Scottsdale, Phoenix, Chandler, Gilbert, Mesa, Tempe, Glendale, and Fountain Hills — all of Maricopa County, AZ. We are not generalists. We are the licensed electrical specialists people call after they have been burned by someone who was not. And when we are done, you will know with certainty that your home or business is safe, modernized, and ready for whatever comes next.
Your Panel Is the Heart of Your Home — Treat It That Way
Most homes built before the late 1990s were designed around a world without EV chargers, dual-zone HVAC systems, whole-home generators, induction ranges, or a home office pulling power all day. A 60-amp or 100-amp panel was standard once. Today it is a bottleneck — or worse, a hazard. If your panel is 20, 30, or 40 years old, the question is not whether you need to upgrade it. The question is how long you are willing to wait.
For Scottsdale homeowners running a kitchen remodel, adding a new HVAC system, or planning an EV charger circuit in the garage, an underpowered panel is a real daily problem. For restaurant owners and medical office managers, a partial power outage mid-service or mid-procedure is not just an inconvenience — it is a liability. We understand both worlds, and we solve both problems the right way.
“The goal is not just a new panel. The goal is a home or business that runs the way you actually live and work — safely, reliably, and without compromise.”

Electrical Panel Upgrades: What We Do
Every upgrade we perform starts with a thorough home electrical load assessment. We evaluate your current amp service size, the number of circuits, existing wiring condition, and what your lifestyle or business actually demands today — and in five years. Then we give you a clear, written scope with no surprise invoices. Here is what a full panel upgrade with FHR Electric typically includes:
- Main panel replacement — Swapping out your old, undersized, or hazardous panel for a modern, code-compliant unit from a trusted manufacturer.
- 200-amp panel upgrade (and beyond) — The 200-amp service size for a home is now the standard baseline. Larger homes, two EV charger setups, or properties with high-draw equipment may need 320-amp or 400-amp service.
- Hazardous panel replacement — Federal Pacific, Zinsco, and other recalled panel brands are still found in older Scottsdale and Phoenix properties. If you have one, it needs to come out. Full stop.
- Subpanel installation — A subpanel for a detached garage, casita electrical hookup, or addition is often the cleanest solution when running more circuits back to the main panel is not practical.
- Underground meter upgrade — If your utility service entrance needs to be upgraded alongside the panel, we coordinate the full scope from meter base to breakers.
- Panel surge protector installation — Arizona’s monsoon season is no joke. A whole-home surge protector at the panel protects every appliance and device in your home from a single point.
- Arc-fault and GFCI breaker installation — Modern code requires arc-fault protection in bedrooms, living areas, and other zones. We bring your panel up to current NEC standards as part of every upgrade.
- Permit and inspection management — Every panel upgrade in Maricopa County requires a permit and a city inspection. We handle it all. No grey-area work, no skipped steps.
EV Charger and High-Load Circuit Additions
Scottsdale has one of the highest concentrations of Tesla and EV ownership in Arizona, and adding a Level 2 charger to a home with an old 100-amp panel is almost always a conversation about upgrading the panel first. We plan the complete picture: EV charger rough-in for the garage, dedicated circuit sizing, and — for homeowners also running solar — how to handle an EV charger and solar on the same electrical panel cleanly and safely. We also handle two-EV-charger home setups, EV charger wiring cost conversations specific to Arizona, and can advise on solar battery and EV charger combo configurations as part of your broader energy strategy.
Beyond EV chargers, we regularly add dedicated circuits for wall ovens, hot tubs (which carry their own dedicated circuit requirements), radiant floor heating electrical wiring, residential elevator circuits, and pergola electrical wiring. If your lifestyle demands it, we wire it — correctly, with a permit, and built to last.
Commercial Panel Upgrades and Load Balancing
Business owners in Chandler, Gilbert, Tempe, and Old Town Scottsdale face a different set of stakes. For a restaurant, losing power to a reach-in cooler or a commercial espresso machine at 8 AM on a Saturday morning is a revenue and health-code crisis. For a dental or medical office, an unexpected shutdown is a patient safety issue. We perform three-phase load balancing, service upgrades for commercial rooftop HVAC electrical connections, and panel work for electrical for commercial coffee equipment, walk-in coolers, and specialty medical equipment — all coordinated around your schedule to protect your uptime. Learn more about our dedicated restaurant electrical services and medical and dental office electrical services if your needs go beyond the panel itself.
Why This Matters More Than You Think
An outdated or undersized electrical panel is not just a nuisance. It is one of the leading contributors to residential electrical fires in the United States. Heat damage to electrical wiring, breakers that are not actually tripping when they should, and arc faults that go undetected — these are real risks hiding behind a metal door in your utility closet or garage. If you have ever noticed a partial power outage in your home, flickering lights, or a circuit breaker that simply stops working, those are not quirks to live with. They are warning signs.
Beyond safety, there is real financial logic here. Scottsdale’s real estate market is competitive, and buyers at the mid-to-high price point — and their lenders — do not overlook FHA wiring requirements in Arizona or aging panels. A home addition electrical permit, a kitchen remodel electrical sign-off, or an EV charger installation all become smoother when the panel behind them is modern and properly sized. An upgraded panel is not an expense. It is an investment in your home’s value, insurability, and livability.
If you have ever wondered how old your panel should be before replacing it, the honest answer is: if it is over 25–30 years old, or if it is a known hazardous brand like Federal Pacific or Zinsco, the conversation has already started without you.

Why Scottsdale and Maricopa County Homeowners Choose FHR Electric
We know you have options. We also know that after one experience with an unlicensed contractor — failed inspections, dangerous wiring you discovered months later, a project that ballooned in cost — you are not taking chances again. Here is what separates us:
- Fully licensed, bonded, and insured — We hold a valid Arizona ROC license. You can look it up. That is what a legitimate electrical contractor looks like. No exceptions, no workarounds.
- Transparent, written estimates — We scope the job before we quote it. No surprise invoices, no scope creep without a conversation first.
- Permit-pulled, inspection-passed work — Every panel upgrade goes through the proper permitting process with your local municipality. You get documentation you can show a buyer, an insurer, or a lender.

Our Process: Simple, Straightforward, No Surprises
Here is exactly what happens when you call us for an electrical panel upgrade:
- Free assessment and written quote — We come out, evaluate your current panel, perform a home electrical load assessment, and walk you through your options. You get a written quote before any work is scheduled.
- Permit application — We pull the permit with your city or municipality. In Scottsdale, Phoenix, Chandler, and across Maricopa County, panel upgrades require one. We handle all of it.
- Scheduled installation — We work around your schedule. For residential clients, we minimize the time your home is without power. For commercial clients, we plan around your operating hours to protect your uptime.
- City inspection and sign-off — After installation, the city inspector comes out and verifies the work. We coordinate that appointment and are available to walk the inspector through our work.
- Final walkthrough with you — Before we close out the job, we walk you through your new panel, explain each circuit, and answer every question. You leave knowing exactly what you have.
If your upgrade is part of a larger project — a home addition, a kitchen remodel, a new HVAC system, or an EV charger installation — we can coordinate the full electrical scope so you have one team, one point of contact, and one accountability structure. We also offer electrical troubleshooting and code correction if we discover wiring issues behind the walls during the upgrade process. Nothing gets covered up. Everything gets fixed.
