Serving Ontario and the surrounding area
We cover every part of Ontario — Ontario Ranch, Creekside and downtown Ontario included — along with the neighboring communities of Montclair and Rancho Cucamonga.
Ontario sits in San Bernardino County, and the electrical work here reflects that mix: older housing stock that needs grounding, capacity and device upgrades, alongside newer construction that simply needs more circuits than it was built with. Crews route through the Inland Empire daily, so travel time to a call in Ontario is short.

How a Ontario service call works
You call, we answer
A dispatcher picks up 24 hours a day and gets the details — what is happening, where, and how urgent.
We diagnose before we price
The electrician tests and inspects, then explains what is actually wrong in plain terms.
You approve a flat price
One number for the whole job, agreed before any work starts. No hourly meter.
We do the work and clean up
Parts on the truck for most jobs, permits pulled where required, circuits labeled at the end.
What affects the price in Ontario
| Type of work | Device replacements and small repairs are the low end; panel upgrades, rewires and generator installs are project-priced. |
|---|---|
| Age of the wiring | Older Ontario homes may need grounding, box replacement or circuit separation before the requested work can be done safely. |
| Access | Attic, crawlspace and wall access drives most of the labor difference between two otherwise identical jobs. |
| Permits | Panel, service, EV and rewire work is permitted, and that cost is stated in your quote up front. |
| Timing | Emergency and after-hours calls are quoted flat, so urgency does not turn into an open-ended bill. |
One number, agreed first
We diagnose, explain what is wrong, and give you a flat price for the whole job before any work starts. If you decide not to proceed, that is fine — there is no hourly meter running while you think about it.
What Ontario customers say
Half my kitchen went dead and two other people had already guessed at it. These guys traced it to a bad connection in a box behind a cabinet in about forty minutes.
Priya S.Ontario, CATesla Wall Connector installed, conduit run neatly along the garage wall, permit handled. Charges overnight now instead of trickling all week.
Anthony V.Ontario, CAGenerator sized properly, transfer switch installed, and they tested it under load. Ran the whole house through the last shutoff without us touching anything.
Greg H.Ontario, CAElectrician FAQs for Ontario
What is the most common electrical problem you see in Ontario?
Capacity. A large share of Ontario homes were wired for a fraction of today's load, so panels run out of slots, kitchen circuits trip, and there is nowhere to land an EV charger. A panel upgrade solves most of it at once.
Can you find a problem another electrician could not?
Often, because intermittent faults need testing under load rather than a visual check. Loose neutrals, back-stabbed connections and buried junction boxes are the usual culprits, and all three are findable with the right approach.
Which areas around Ontario do you cover?
We work throughout Ontario and the surrounding communities, including Montclair, Rancho Cucamonga, Chino and Upland, plus the wider the Inland Empire area.
Do you handle both homes and businesses in Ontario?
Both. The same crews do residential repairs and installations during the day and commercial work — offices, restaurants, retail and warehouses — on nights and weekends so Ontario businesses can stay open.
How much does an electrician cost in Ontario?
Most jobs in Ontario are quoted flat rather than hourly, so you approve one number before work begins. Small repairs and device replacements sit at the low end; panel upgrades, EV circuits and rewires are priced after we look at the service and the access.
Do you pull permits for electrical work in Ontario?
For work that requires it — panel and service upgrades, EV charger circuits, rewires, new circuits and generator installs — yes. We pull the permit with the local jurisdiction and meet the inspector.
