## Generator Installation in Ontario, CA

Public safety power shutoffs and storm outages made backup power a normal purchase in Ontario rather than a luxury. The generator is the easy part. Deciding what it has to carry, and wiring the transfer equipment correctly, is the job.

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

### Whole house or essential circuits

A critical-load subpanel is far cheaper than whole-house coverage and keeps heat, refrigeration and internet running. We price both.

### Existing generator won't start on outage

Usually the transfer switch, the battery or the exercise routine, not the engine. We diagnose the switching first.

### Extension cords through a window

Common and genuinely dangerous. An inlet box and interlock costs a fraction of a standby unit and ends the practice.

### Not sure what size to buy

We meter and calculate rather than estimate. Most Ontario homes land between 14kW and 26kW depending on AC, well pumps and electric ranges.

## Reviews from San Bernardino County

★★★★★

We needed a 200 amp panel before our EV charger install. They did the load calculation, pulled the permit, and had the whole thing done and inspected in a week.

Priya N.Panel upgrade · Ontario
★★★★★

Tesla 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.

Devon W.EV charger · 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.

## Generator Installation in Ontario — questions

Can you install a battery instead of a generator in Ontario?

Yes. Battery backup runs silent, needs no fuel and pairs with solar, but has a fixed energy budget. For multi-day PSPS events a generator still wins on runtime.

Will the generator start automatically when the power goes out?

With an automatic transfer switch, yes, typically within 10 to 30 seconds. With a manual switch or interlock you start it and flip the switch yourself, which is a cheaper install.

How often does a standby generator need service?

An annual service plus the weekly self-exercise cycle. The exercise routine matters more than owners expect, because it is what catches a dead battery before an outage does.

Do I need a permit to install a generator in Ontario?

Yes, and often a gas permit too. We handle the electrical permit and inspection and coordinate with your gas contractor or plumber.

How much does a whole house generator cost in Ontario?

The unit is roughly half the project. The rest is the transfer switch, pad, gas line, electrical and permit. Sizing drives everything, so call (833) 652-8933 and we will run a load study before quoting.
