Our Process
How Our Commercial Electrical Process Works
We built our process around one goal: getting your facility back to full operation with as little disruption to your business as possible. Every project starts with a conversation about your schedule, your equipment, and any code requirements tied to your industry.
-
Step 1: Site Assessment and Scope Review
We walk your facility with you to review existing wiring, panels, and equipment, then discuss the upgrade or repair you need and any code considerations specific to your building.
-
Step 2: Written Estimate and Scheduling
You receive a clear, itemized estimate before any work begins. We schedule the job around your operating hours whenever possible to limit downtime.
-
Step 3: Commercial Electrical Installation or Repair
Our electricians complete the work to code, whether that is a panel upgrade, new wiring for equipment, or troubleshooting an intermittent fault across your building.
-
Step 4: Testing and Final Walkthrough
Every circuit is tested under load before we close out the job. We walk the site with you again to confirm everything is working and answer any questions about maintenance going forward.

Commercial electrical questions
Frequently Asked Questions
How do I know if my facility needs a commercial electrical upgrade?
Frequent breaker trips, flickering lights, warm outlets, or a panel that is already at full capacity are common signs. If you are adding new equipment, expanding square footage, or installing EV charging, a licensed electrician should evaluate whether your current service can handle the added load.
Can you perform electrical repairs without shutting down our business?
In many cases, yes. We plan commercial electrical repair and installation work around your operating hours and, where possible, isolate circuits so unaffected areas of your building stay powered while we work.
What is involved in a 200 amp service upgrade for a commercial building?
A 200 amp service upgrade typically involves replacing the main panel, upgrading the service entrance wiring, and coordinating with your utility company for the meter and connection. We handle the permitting and inspection process as part of the job.
Do you offer ongoing electrical maintenance plans for businesses?
Yes. Scheduled electrical maintenance helps catch loose connections, overloaded circuits, and worn components before they cause an outage or a safety hazard. Ask us about setting up a recurring inspection schedule for your facility.

Mr. Castillo was prompt for the scheduled appointment, he came equipped with his tools/van/uniform. He went to work immediately, friendly, knew where to trouble shoot the electrical problem, corrected the problem within one hour of arrival while running down to the basement and up to the second floor bedroom several times where my daughters lights had gone out. I recommend this electrical expert to repair your electrical issues and he can also communicate in spanish , I give this company five stars *****!

I recently had several electrical issues at my home and was fortunate to find Amubury. He arrived promptly and was able to accurately diagnose the problems within minutes. I was incredibly impressed that he was able to fix everything in just a couple of hours. He even took the initiative to run out and purchase a necessary replacement part himself, which kept the process moving efficiently without any delays. Throughout the entire experience, Amubury was professional, courteous, and highly efficient. What stood out most was how thorough he was—he took the time to clearly explain the issues and walked me through the solutions, making sure all of my questions were answered. His pricing was very reasonable given the high quality and speed of his work. I was genuinely impressed and would highly recommend his services to anyone in the area. I will certainly be calling him again for any future electrical needs!

I was lucky enough to meet Amaury when I moved into my “new” home almost 10 years ago and he has been my go- to for everything electrical since! From installing a new fan on a cathedral ceiling to recessed and living room spotlights to changing out fan switches in bathrooms - he has done it all. Fast, responsive, fair and courteous- I really can’t say enough about Amaury, he truly is the BEST. Thanks Amaury!

We lucked out when I found Amaury on Angie's List years ago. Since then, he's fixed issues that have cropped up, installed a generator hook-up, and then replaced our entire (very old) electrical panel. He's responsive, thorough, knowledgable, insightful, voluntarily explains things and is fairly priced. Cannot recommend him enough!

Couldn’t be happier with our electric panel upgrade! From start to finish, the process was smooth and stress-free. Amaury was knowledgeable, respectful of our home, and did excellent work. Everything works perfectly and the upgrade gives us real peace of mind. I’d absolutely use them again.

Amaury quickly came over to check over the electrical wiring for our generator and electrical box, making a couple of thoughtful suggestions and quickly ensuring that we had heat in the event of a power outage in the Jan '26 snowstorm. Would recommend Amaury for any number of electrical work.

Amaury was super knowledgeable, efficient (he didn’t waste time), and I appreciate that he was conscious of the neat and clean look of the job putting in some complicated ceiling lighting. He asked me my opinion along the way so as to get just what I wanted while completing the job. And he left no mess behind. Thank you Amaury- first time using your service. Looking forward to having you as a reliable electrician for future jobs.
