## Situations we see in Corona

### 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.

### 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.

## Reviews from Riverside County

★★★★★

Breaker tripped Sunday night and I got a call back in about ten minutes. Tech found a bad connection in a junction box behind the closet, fixed it that night, and the price was what he said on the phone.

Six recessed lights in the living room and a dimmer that finally doesn't buzz. They laid the whole layout out on the ceiling with tape first, which I appreciated.

Our restaurant lost the walk-in circuit on a Friday. They came out after close, traced it to a failed feeder lug, and we opened Saturday on time.

## Commercial Electrician in Corona — questions

Can you install commercial EV charging in Corona?

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

Can you work after hours so my Corona 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.

How fast can you respond to a commercial outage?

Same-hour dispatch in most of Riverside County, 24 hours a day. Restaurants and medical spaces get priority because refrigeration and life-safety systems don't wait.

Do you handle tenant improvements in Corona?

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

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.
