Electrical Services We Provide in Ontario

Complete residential and commercial electrical services for Ontario homes and businesses.

Electrical Panel Upgrade

Upgrade your existing electrical panel from 100-amp to 200-amp service. Common in older Downtown Ontario homes that still have original electrical service, and increasingly in newer Ontario Ranch homes adding EV chargers and ADUs.

EV Charger Installation

EVITP-certified Level 2 EV charger installation for Ontario homeowners. We install all major brands — Tesla Wall Connector, Wallbox, ChargePoint, Emporia, Grizzl-E. Many Ontario homeowners qualify for SCE Charge Ready Home rebates up to $4,200.

Commercial Electrical Services

Tenant improvements (TI), commercial lighting upgrades, panel/service upgrades, code compliance, and EV chargers for commercial fleets. Ontario's commercial and industrial properties — from Ontario Mills retailers to warehouses near the airport — all need quality electrical work.

Electrical Panel Replacement

Replace outdated or recalled electrical panels including Federal Pacific (FPE) and Zinsco panels. Many older Ontario homes still have these recalled panels that insurance companies now require be replaced.

Electrical Troubleshooting

Diagnose and fix electrical problems — flickering lights, tripping breakers, dead outlets, faulty switches. Same-day service available for emergency situations in residential and commercial properties.

ADU Electrical Installation

Ontario has been actively encouraging ADU construction. We install ADU electrical including dedicated subpanels, separate metering options, and complete electrical service for new accessory dwelling units throughout Ontario.

Electrical Issues Common in Ontario Homes & Businesses

Ontario’s mix of older homes near downtown, post-war tract neighborhoods, and rapidly growing newer developments creates a wide variety of electrical issues. Here’s what we encounter most often when serving Ontario customers:

Older Downtown Homes Need Panel Upgrades

Many Downtown Ontario homes built in the 1900s-1950s still have original electrical service — often 60-amp or 100-amp panels that can’t support modern electrical loads. Panel upgrades are one of the most common requests in older Ontario neighborhoods.

Federal Pacific Panel Replacement

Many Ontario homes built in the 1960s-1980s received Federal Pacific or Zinsco panels — both linked to safety defects. Insurance companies increasingly require these be replaced. We safely replace recalled panels with modern Eaton, Square D, or Siemens equivalents.

New Model Colony EV Charger Demand

The newer New Model Colony and Ontario Ranch developments have growing EV adoption. Most homes have 200-amp panels, but adding Level 2 chargers requires careful load assessment. We’re EVITP certified for proper EV charger installation.

Commercial Code Compliance

Ontario’s commercial properties — particularly older buildings near downtown and the airport — often need electrical updates to meet current code for tenant improvements, occupancy changes, or sale prep. We handle commercial code compliance work.
