Situations we see in Fontana
Build-out on a deadline
Rough-in, inspection and trim get sequenced against the general contractor's schedule so electrical is never the trade holding up the certificate.
Breakers trip during service hours
We thermal-scan and log the panel under real load rather than guessing, then rebalance or add capacity to whatever is running hot.
Lighting bill is too high
High bay and troffer LED retrofits are the fastest payback in a commercial building, and they usually improve light levels at the same time.
Equipment needs a new feeder
New machinery often needs its own three-phase circuit and disconnect. We size it, land it and coordinate the shutdown for a slow hour.

Reviews from San Bernardino County
Zinsco panel replaced. Straight quote, one day of work, and they handled the utility disconnect scheduling so I didn't have to call anyone.
Yasmin K.Panel replacement · FontanaKitchen breaker kept popping whenever we ran the microwave and kettle. They put in a dedicated circuit instead of just telling us to use one appliance at a time.
Alicia G.Dedicated circuit · FontanaTesla Wall Connector in the garage, clean conduit run, done in an afternoon. They talked me out of a panel upgrade I didn't actually need.

Do you handle tenant improvements in Fontana?
Regularly. Demolition, rough-in, panel schedules, lighting, low voltage rough and final trim, coordinated with the GC and the inspector.
Can you work after hours so my Fontana business stays open?
Yes, and for most commercial clients that is the default. Tell us your quiet window and we will schedule the shutdown inside it.
Do you offer maintenance agreements?
Yes. Scheduled panel inspections, thermal scans, emergency lighting tests and lamp or driver replacement, on a plan that fits your building.
How fast can you respond to a commercial outage?
Same-hour dispatch in most of San Bernardino County, 24 hours a day. Restaurants and medical spaces get priority because refrigeration and life-safety systems don't wait.
Can you install commercial EV charging in Fontana?
Yes, from a couple of employee stalls to fleet depots, including load management so you don't blow past your demand charges.
