A sparking outlet at 6 a.m. before your restaurant opens. A breaker that won’t stop tripping in your dental office — right in the middle of a patient procedure. An aging panel in your Old Town Scottsdale retail space that was installed long before you ever signed the lease. These aren’t minor nuisances. They’re real hazards, real liability, and real money walking out the door every minute your business can’t operate at full capacity. At FHR Electric, we built our Commercial Electrical Repairs practice specifically for business owners, property managers, and commercial tenants across Scottsdale, Phoenix, Chandler, Gilbert, Mesa, Tempe, Glendale, and Fountain Hills who refuse to gamble on their building’s electrical system — and who have been burned enough times by unlicensed subs to know that price alone is never the right filter.
The Real Cost of a Broken or Outdated Commercial Electrical System
Most electrical problems in commercial buildings didn’t start yesterday. They’ve been building — literally inside your walls — for years. A panel that wasn’t sized for today’s loads. Wiring that was roughed in by whoever was cheapest during the original build-out. Circuits that were never labeled accurately, breakers that trip without warning, and outlets that show all the classic signs of a circuit overload. If any of that sounds familiar, you’re not alone, and you’re not imagining it.
For restaurant owners, the nightmare scenario is losing power to your walk-in cooler mid-service, or having your commercial kitchen go dark because the panel can’t handle the restaurant equipment electrical load that was added when you upgraded the line. For medical and dental offices, a single power interruption can compromise patient safety, damage expensive equipment, and expose you to liability no insurance policy fully covers. For property managers and commercial landlords, unpermitted electrical work discovered during due diligence — or worse, after a sale — can unravel an entire transaction and land you in legal territory you never anticipated.
The dangers of unlicensed electrical work aren’t theoretical. They show up in insurance claim denials, failed inspections, and fires. At FHR Electric, every technician on our commercial team is licensed, insured, and pulls the permits required by Maricopa County jurisdictions — every single time. No shortcuts. No gray areas.
Commercial Electrical Repairs: What We Fix and Why It Matters
Our Commercial Electrical Repairs services cover the full range of problems that cause downtime, safety violations, and insurance headaches for Scottsdale-area businesses. Here’s what we handle every week for commercial clients across Maricopa County:
Breaker and Panel Problems
- Tripping breakers and circuit overloads — If your breakers are tripping regularly, that’s your system screaming that the load is too high for the circuit. We diagnose the root cause and fix it — not just reset it and walk out.
- Unbalanced panel load — An improperly balanced panel stresses the electrical system unevenly, shortens equipment life, and can cause neutral wire overheating. We identify and redistribute loads correctly.
- Tandem breaker code violations — Tandem breakers are sometimes installed to save panel space, but they are not code-compliant in every situation. We assess your panel’s current configuration and correct violations before they become inspection failures.
- Panel upgrades and old fuse box replacement — Many Maricopa County commercial buildings, especially those built before the 1990s, are running on panels that were never designed for modern electrical loads. We perform complete panel upgrades and panel replacements with proper permitting, including coordinating with APS or SRP as required.
- Breaker label accuracy — Mislabeled or unknown circuits are a safety risk and a red flag during any electrical due diligence for commercial property. We map, test, and properly label every circuit in your panel.
Outlets, Circuits, and Wiring Repairs
- Ungrounded outlets — Common in older commercial spaces, ungrounded outlets pose a shock hazard and can damage sensitive electronics and medical equipment. We upgrade them correctly — not with a simple adapter that masks the problem.
- Circuit losing power with no tripped breaker — One of the most common service calls we receive. This usually points to a loose connection, a failing breaker, or a wiring fault. We track it down and fix it at the source.
- Ghost kitchen and restaurant equipment electrical — High-draw commercial cooking equipment, specialty ventilation, and ghost kitchen buildouts require dedicated circuits sized and wired to code. We handle it from design through final inspection.
- Commercial tenant improvement wiring and shell space electrical build-outs — Moving into a new commercial space? We wire it from shell to functional, coordinating with your GC so the project stays on schedule.
- Dedicated circuits for heavy equipment — Whether it’s a 240V induction range, a commercial HVAC or ductless mini split, or a welder outlet installation in a commercial garage, we run the dedicated circuit properly — sized, labeled, and inspected.
Lighting, Low Voltage, and Specialty Commercial Services
- Commercial LED upgrade — Replacing old fluorescent or HID fixtures with commercial-grade LED not only cuts your utility bill but also improves light quality for employees and customers. We handle full fixture replacement and controls integration.
- Cove lighting and specialty architectural lighting — For restaurants, medical offices, high-end retail, and hospitality clients in North Scottsdale and beyond, we install cove lighting and specialty systems that deliver the ambiance your brand requires.
- AV room wiring and low voltage rough-in — Conference rooms, waiting rooms, and executive suites need clean, organized low voltage infrastructure. We plan and install it right the first time.
- Fleet EV charger wiring and Level 2 commercial charging stations — With EV adoption accelerating across the Phoenix metro, commercial property owners are fielding tenant and employee requests for on-site charging daily. We design and install commercial-grade EV charging infrastructure, including fleet EV charger wiring for multi-vehicle deployments. For smaller-scale projects, visit our EV charger installation services page to learn more.
- Commercial generator installation and backup power — For businesses where any downtime is unacceptable, we install and maintain commercial standby generators. See our full commercial generator installation and maintenance services for details.
- Pool bonding inspection and pool light replacement — Commercial properties with pools — hotels, resorts, multi-family — require regular bonding inspections and properly wired underwater lighting. We handle both.
“We don’t patch problems. We find the source, fix it permanently, and document everything so you have a clear record for your insurance carrier, your landlord, or your next buyer.”

- Initial Assessment Call: When you call (602) 492-9999, you speak with a knowledgeable team member — not a call center script. We ask the right questions upfront to understand your situation, your urgency, and your building type before we ever roll a truck.
- On-Site Diagnostic: Our licensed technician arrives on time, evaluates your electrical system thoroughly, and identifies not just the obvious symptom but the underlying cause. We check panel age and condition, circuit loading, grounding, bonding, and code compliance during every visit — because we want to catch the issue behind the issue.

- Licensed Repairs with Proper Permits: Our team performs the work to code, pulling permits where required. We use commercial-grade materials and follow NEC standards and Arizona-specific requirements for every repair and installation.
- Inspection Coordination: When permits are involved, we coordinate the inspection and ensure it passes. You receive documentation of the completed, inspected work for your records — valuable for insurance, property management files, or future due diligence.
- Final Walkthrough and Documentation: Before we leave, we walk you through what was repaired or installed, answer any questions, and confirm everything is operating correctly. You’ll have a clear record of the work performed — something a fly-by-night operator will never hand you.
