The power goes out. It happens more than most people expect in Scottsdale, AZ — summer monsoons, grid surges, utility failures — and when it does, the consequences range from a spoiled refrigerator to a genuine safety emergency. If you run a medical or dental practice, a restaurant, or a home that depends on powered medical equipment, losing electricity is not an inconvenience. It is a crisis. That is exactly why Standby Generator Installation has become one of the smartest investments Maricopa County property owners are making right now. At FHR Electric, we install, connect, and maintain whole-home and commercial standby generator systems so that when the grid goes dark, your lights, your HVAC, your refrigerators, and your critical equipment never miss a beat.
We are a licensed, bonded, and insured electrical contractor serving Scottsdale, North Scottsdale, Old Town Scottsdale, Phoenix, North Phoenix, Chandler, Gilbert, Mesa, Tempe, Glendale, Fountain Hills, and all of Maricopa County. Every generator project we touch is permitted, inspected, and completed by a certified electrician — never a handyman, never an unlicensed sub. If you have been burned before by someone who cut corners, you will immediately feel the difference in how we work.
Why Scottsdale Homeowners and Business Owners Are Installing Standby Generators Now
Arizona’s electrical grid is under more stress than ever. Peak summer demand, aging infrastructure, and rapid population growth across the Valley all contribute to outages that can last hours — or days. Meanwhile, modern homes and businesses are running bigger loads than ever: multi-zone HVAC systems, EV chargers, smart home technology, home offices, and high-end kitchen appliances. A portable gas generator from a big-box store is not the answer. It is a temporary band-aid that leaves you scrambling with extension cords while your freezer thaws and your sump pump sits idle.
A properly installed standby generator is a permanent, automatic solution. It is wired directly to your home or business through a generator transfer switch installation — either an automatic transfer switch (ATS) or a manual transfer switch — so the moment utility power drops, your generator starts and takes over within seconds. No extension cords. No hauling fuel. No fumbling in the dark. You probably will not even notice the power was out.
Understanding what size unit you need is the first real question to answer. People ask us all the time: how many watts do I need for a whole-home generator? The honest answer depends on your home’s square footage, your electrical panel capacity, what loads you want to support, and whether you are also planning a solar or battery backup integration. We walk through every one of those factors with you before we ever quote a number.
Our Standby Generator Installation Services
We handle every piece of a generator project from the initial load calculation through the final inspection. Here is what that looks like in practice:
Whole-Home Standby Generator Installation
We install air-cooled and liquid-cooled standby generators from industry-leading brands, including Generac — one of the most requested names we hear from Scottsdale homeowners asking about a Generac install in Arizona. We handle the complete electrical scope: transfer switch, dedicated circuit, proper grounding, conduit runs to code, and coordination with your gas utility for fuel connection. Every installation is permitted through the city or county and passes inspection. If your panel needs an upgrade to support the generator load — which is common on older homes — we handle that too. You can read more about our new circuit installation services to understand how we approach adding dedicated power for major equipment.
Automatic Transfer Switch (ATS) Installation
The transfer switch is the brain of your backup power system. An automatic transfer switch monitors utility power continuously and triggers your generator to start the moment it detects an outage — typically within 10 to 30 seconds. We size and install the right ATS for your system, whether that is a whole-home unit or a critical-loads panel that protects your most important circuits first. This is where the generator transfer switch installation is done right, to code, with no shortcuts on wire sizing or bonding.
Standby Generator Auto-Exercise Setup
A generator that sits idle for months and then fails during an actual outage is worse than useless. We program a standby generator auto-exercise setup as part of every installation — a scheduled weekly or bi-weekly run cycle that keeps the engine lubricated, the battery charged, and the system ready. We set this up through the generator’s onboard controller and walk you through how to monitor it.
Commercial Standby Generator Installation
For business owners, a power outage is not just uncomfortable — it is a financial and liability event. We install and maintain commercial standby systems for restaurants, medical and dental offices, retail spaces, and multi-tenant buildings across the Valley. If you run a practice that uses imaging equipment or life-critical systems, our team also specializes in medical and dental office electrical services and understands exactly what your uptime requirements demand.
Restaurant owners know the math: a single dinner service lost to an outage can cost thousands. Pair your generator installation with our restaurant electrical services to make sure your entire electrical system — generator, panels, kitchen circuits, and lighting — is built to handle real commercial demands.
Generator Maintenance & Annual Service
A standby generator is a piece of mechanical and electrical equipment that needs regular care. Our maintenance visits include:
- Oil and filter change
- Spark plug inspection and replacement
- Air filter service
- Battery load test and replacement as needed
- Transfer switch operation test
- Voltage and frequency output verification
- Fuel system inspection (natural gas or propane)
- Visual inspection of wiring, connections, and grounding
- Exercise schedule verification and reset
- Full electrical safety check on the connected panel circuits
We also offer ongoing preventative commercial electrical maintenance programs for business owners who want a single, accountable team managing all of their electrical reliability — not just the generator.
Whole Home Surge Protection
Every generator installation we complete includes a conversation about whole home surge protection. When utility power is restored after an outage, the returning voltage surge is one of the most common causes of appliance and electronics damage. We install panel-level surge protection devices as part of a complete backup power solution so your investment in smart home technology, home audio, and electronics is protected from both sides of an outage.
What Makes a Generator Installation Done Right
We have seen what happens when a generator is installed by someone who does not pull permits, does not size the transfer switch correctly, or does not follow the manufacturer’s clearance requirements. The system fails at the worst possible moment, or worse — it creates a backfeed hazard that puts utility workers and your own household at risk. That is not a scenario we are willing to accept.
“Every generator project we complete is permitted, inspected, and backed by a licensed Arizona electrical contractor. When you need it most, you can trust it will work.”
— FHR Electric
Here is what separates a professional standby generator installation from a shortcut job:
- Proper load calculation — We calculate your actual electrical demand before recommending a generator size, so you are not overpaying for capacity you do not need or under-powered when it counts.
- Correct transfer switch type and rating — The transfer switch must match your panel’s main breaker amperage and the generator’s output. Mismatch here is dangerous.
- Code-compliant clearances — Arizona and local jurisdictions have specific requirements for where a generator can be placed relative to windows, doors, gas meters, and property lines. We know those rules and follow them.
- Licensed and permitted work — Every installation is pulled with a permit. You can verify our license any time through the Arizona Registrar of Contractors (what many clients call checking an ROC number). We have nothing to hide.
- Proper grounding and bonding — Generator grounding is often missed by non-specialists. It is critical for safety and required for inspection approval.
- Manufacturer startup and commissioning — We perform a full load test before we leave, confirm the auto-transfer functions correctly, and walk you through the system.
You can learn more about how standby generator systems work at a technical level through Wikipedia’s resource on standby generator installation and maintenance. Understanding the basics helps you ask better questions and spot the difference between a thorough proposal and a low-ball number that leaves out critical components.
Our Process: From First Call to Final Inspection
We believe in full transparency at every step. Here is how a typical generator project moves from inquiry to completion with FHR Electric:
- Site assessment and load calculation — A licensed electrician visits your property, reviews your electrical panel, identifies your critical loads, and measures available space for equipment placement. No guessing, no quoting over the phone without seeing the job.
- Proposal and scope review — You receive a clear, written proposal that includes generator model, transfer switch type, conduit routing, panel work if needed, permit fees, and our warranty. No line items buried in fine print. If you are comparing bids, use these details as your checklist — vague proposals are a warning sign.
- Permit application — We handle the permit with your local jurisdiction. In Scottsdale and across Maricopa County, generator installations require an electrical permit. We do this every day and know how to move it efficiently.
- Installation day — Our crew arrives on time, protects your property, completes all electrical and mechanical connections, and does not leave until the system has been tested under load and the auto-exercise schedule is programmed.
- Inspection — We coordinate the city or county inspection and walk the inspector through the installation. We have a strong inspection pass record because we do not cut corners going in.
- Owner walkthrough — We show you exactly how your system works, what the indicator lights mean, how to manually operate it if needed, and when your first maintenance service is due.
