If you own or manage a business in Scottsdale or anywhere across Maricopa County, you already know that your electrical system is not background noise — it is the backbone of everything you do. One tripped breaker at the wrong moment shuts down your restaurant mid-service, interrupts a procedure at your medical office, or brings a busy warehouse to a complete stop. And if your building still runs on an aging panel that was never designed for today’s commercial loads — the commercial kitchen equipment, the HVAC, the server room, the EV fleet chargers — you are not just risking inconvenience. You are risking liability, failed inspections, insurance problems, and the kind of downtime that costs you real money and real customers. We are FHR Electric, and Commercial Electrical Installation Services is what we do every single day across Scottsdale, Phoenix, Chandler, Gilbert, Mesa, Tempe, Glendale, Fountain Hills, and the rest of Maricopa County, AZ. We are the licensed, experienced team that business owners and property managers call when the stakes are too high to gamble on a generalist.
What a Properly Installed Commercial Electrical System Actually Gives You
Here is the honest truth: most business owners do not think about their electrical system until something goes wrong. A buzzing outlet, an overloading panel, a circuit losing power with no tripped breaker — these are not random annoyances. They are symptoms. And when they show up in a commercial setting, the consequences are not just inconvenience. They are OSHA violations, failed electrical certificates of occupancy, voided insurance policies, and fire hazards that could end your business entirely.
What a properly designed and installed commercial electrical system gives you is the opposite of all that. It gives you certainty. You walk in, flip the switch, and nothing in your building is a hidden hazard. Your loads are balanced correctly. Your circuits are sized for what they actually carry. Your panel has room to grow. Your team works safely, your equipment runs reliably, and your inspections pass the first time. That is what FHR Electric delivers — not a patch job, not the cheapest bid, but a system built to code and built to last.
“We do not just wire buildings. We give business owners and property managers the confidence that their electrical system will never be the reason something goes wrong.”
— FHR Electric Team
Commercial Electrical Installation Services We Provide
We handle the full scope of commercial electrical work — from ground-up new construction to tenant improvement buildouts, from panel upgrades to specialty circuit installations. Here is a closer look at what we do for businesses across Scottsdale and greater Maricopa County.
Commercial Panel Upgrades and Load Distribution
An outdated or undersized panel is the single most common root cause of commercial electrical problems we see. Whether you are running a commercial kitchen with heavy appliance loads, a med spa with sensitive medical equipment, or a mechanic shop that recently added new lifts and compressors, your panel has to be sized and configured for the actual demand. We perform a thorough panel diagnostic, assess your electrical panel load distribution, and install a properly rated panel that can handle today’s loads and tomorrow’s growth. We also correct dangerous issues like double-lugged wiring, improper grounding, and aluminum-to-copper wiring transitions that create heat and fire risk over time.
New Commercial Construction and Tenant Improvement Wiring
We work directly with general contractors, architects, and property managers throughout the buildout process — from rough-in through trim and final inspection. Whether it is a restaurant, a dental or medical office, a retail space, or a warehouse distribution center, we pull the permits, coordinate with the inspector, and deliver a clean electrical certificate of occupancy so your opening day actually happens on time. We understand the unique electrical demands of each commercial environment, including commercial kitchen electrical load calculations, fire suppression system electrical tie-ins, and structured wiring for data and communication networks.
EV Charging Infrastructure for Commercial Properties
EV charging is no longer a perk — it is a competitive advantage and, in many cases, a tenant or customer expectation. We design and install commercial EV charging stations, including 50-amp EV charger installs and WiFi-connected charger systems, for office parks, retail centers, restaurants, and multi-unit residential properties. We also navigate HOA EV charger wiring requirements and help property owners maximize their existing panel capacity before recommending a full upgrade — because adding an EV charger without a panel upgrade is possible more often than people think, when it is engineered correctly from the start.
Commercial LED Lighting Upgrades
A commercial LED upgrade in the Phoenix metro area is one of the highest-return investments a business owner can make. We replace outdated fluorescent and HID fixtures throughout your commercial space — warehouses, parking structures, retail floors, office ceilings — with modern, energy-efficient LED systems. We also install automatic daylight lighting controls and occupancy-based dimming to reduce your utility costs further. The result is better light quality, lower monthly bills, and a noticeably more professional environment. For businesses that want interior ambiance lighting, we also offer specialty in-cabinet LED lighting and architectural lighting solutions.
Subpanels for Detached Structures and Multi-Use Properties
Many commercial properties in the Scottsdale and North Scottsdale area include outbuildings, warehouses, garages, or auxiliary structures that need their own dedicated power. We design and install subpanels for detached structures throughout Arizona, running properly permitted underground feeds and sizing the subpanel to match the actual load — whether it is a workshop subpanel for a mechanic shop, a detached garage electrical panel for a luxury auto dealer, or a separate meter-to-panel feed for a multi-unit residential property. We do this correctly the first time, so you never have to worry about a failed inspection or an unsafe installation discovered during a sale or insurance audit.
Specialty Commercial Circuit Installations
Different businesses have different power requirements that go beyond standard circuits. We install dedicated circuits for tankless water heaters, commercial HVAC units, commercial kitchen equipment, server and IT infrastructure, automatic gate wiring, RV hookup installations, and more. We also handle arc fault and GFCI protection where required by code — including all GFCI requirement locations mandated by the NEC for commercial kitchens, bathrooms, and exterior areas — and we install whole-house power monitor wiring so you always know where your load is going.
Fixing Unlicensed and Substandard Electrical Work
We understand this is a painful subject, and we handle it without judgment. If a previous contractor left your building with wiring that failed inspection, hidden hazards behind the walls, or work that was never permitted, we can assess the full scope, document what needs to be corrected, and bring everything up to current code. Fixing unlicensed electrical work is something we do regularly for businesses in Scottsdale, Tempe, Mesa, and across the county — and it is always better to discover and correct a problem on your timeline than during a sale, an insurance claim, or after an incident.

For business owners who need to keep the lights on no matter what, we also strongly recommend pairing your electrical system with a reliable backup power solution. Our commercial generator installation and maintenance service ensures that a utility outage never becomes a business emergency — whether you run a restaurant, a medical practice, or a multi-tenant property that cannot afford dark hallways and non-functional security systems. And if you want to understand how a commercial transfer switch keeps your business running seamlessly during an outage, we can walk you through every detail during your consultation.
Our Commercial Electrical Installation Process
We do not show up and start pulling wire. We start with a conversation — and then a real assessment — so that everything that follows is planned, priced, and executed without surprises.
- Discovery Call and Site Assessment — We talk through your goals, your timeline, and your current setup. Then we visit the site to assess existing infrastructure, identify any code issues, and fully scope the work before we write a single line on an estimate.
- Detailed Written Estimate — You receive a clear, itemized proposal that tells you exactly what we are doing, what materials we are using, and what it will cost. No vague line items, no bait-and-switch pricing after we open the walls.
- Permitting and Coordination — We handle all permit applications and coordinate directly with the municipality and your general contractor or property manager as needed. We know the inspection schedules and requirements for jurisdictions across Maricopa County.
- Installation by Our Licensed Team — Our own electricians — not subs — execute the work according to the approved plans. We maintain a clean, professional job site and communicate proactively if anything changes.
- Inspection and Final Walkthrough — We schedule and pass the required inspections, then walk you through the completed system so you understand every circuit, every panel, and every safety feature we installed.
- Ongoing Support — We are not a one-and-done contractor. We offer yearly electrical checkups for businesses, emergency service calls, and long-term relationships with property managers who need a dependable electrical partner across multiple sites.
To learn more about what is involved in commercial and industrial electrical work, the Wikipedia overview of commercial electrical installation provides a useful technical foundation — though we are happy to translate any of it into plain English during your consultation.
We also install professional indoor lighting systems for commercial spaces — from recessed lighting in a dental office to full warehouse bay lighting — so you can check multiple items off your buildout list with a single trusted team. And for businesses or property owners who want to protect critical systems from outages, our standby generator installation and maintenance service gives you a permanent, automatic backup solution that kicks in before your staff even notices the grid went down.
