## Commercial Electrician in Ontario, CA

Commercial electrical work in Ontario is judged on one thing: whether you could open the next morning. That is why most of our San Bernardino County commercial jobs happen between close and open, on a schedule agreed before anyone shows up.

Call (833) 652-8933 and describe what is happening. If it is a same-day job we will book it today, and if it needs a site visit to quote properly we will tell you that too.

## Situations we see in Ontario

### 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.

### 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.

### 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.

### 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.

## Reviews from San Bernardino County

★★★★★

Warehouse high bay retrofit to LED. Did it over a weekend so we never stopped shipping, and the place is twice as bright.

Greg L.Warehouse lighting · Ontario
★★★★★

GFCI in the bathroom kept tripping. They found real leakage in an old fixture rather than just replacing the GFCI and calling it done.

Nadia F.GFCI repair · Ontario
★★★★★

Kitchen 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.

## Commercial Electrician in Ontario — questions

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 work after hours so my Ontario 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 handle tenant improvements in Ontario?

Regularly. Demolition, rough-in, panel schedules, lighting, low voltage rough and final trim, coordinated with the GC and the inspector.

Can you install commercial EV charging in Ontario?

Yes, from a couple of employee stalls to fleet depots, including load management so you don't blow past your demand charges.
