Generator Installation across Ontario
We cover every part of Ontario — Creekside, downtown Ontario and Ontario Ranch 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.

What affects generator install pricing in Ontario
| Generator size and cooling type | Air-cooled units cost less to buy and install than liquid-cooled whole-home units. |
|---|---|
| Transfer switch scope | Whole-panel switching costs more than an essential-circuits sub panel. |
| Fuel connection | Natural gas near the pad is simple; a long run or propane tank adds cost. |
| Pad, clearances and placement | Setbacks from windows and property lines can dictate a longer conduit run. |

Recent Ontario feedback
Generator 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, CAOur restaurant cannot close, so they did the panel work overnight. Walked in the next morning to everything working and the floor cleaner than we left it.
Nadia F.Ontario, CAAdded four outlets and GFCI protection in the garage and laundry. Small job, treated like a real one. Fair price, no upsell.
Lorraine T.Ontario, CAGenerator Installation in Ontario — questions we get asked
Can you install a transfer switch for a generator I already own?
Yes. For portable units, an interlock kit or a manual transfer switch is usually the right answer, and it is far cheaper than a standby install.
Do generators need permits in Ontario?
Standby generator installations involve electrical and often mechanical permits in California, plus setback and noise rules that vary by San Bernardino County jurisdiction. We handle the electrical permitting and flag local requirements early.
Will a generator run my EV charger?
Technically yes, practically it is a poor use of fuel. Most owners exclude EV charging from the backed-up loads and keep the capacity for HVAC and refrigeration.
How often does a standby generator need service?
Plan on annual service and a monthly self-test, which most controllers run automatically. Oil, filters and battery are the usual wear items.
What size generator do I need in Ontario?
It depends on whether you want the whole house or essential circuits. Many Ontario homes are well served by a mid-size air-cooled unit with load management; all-electric homes with heat pumps and EVs need more. We run the calculation before quoting.
