Jaclyn provided outstanding customer service and immediately set up an appointment. Jack's knowledge is encyclopedic; his skill is utmost; and his actions are meticulous. He instantly recognized an older GE circuit panel and efficiently replaced the damaged breaker with the appropriate part. Furthermore, the repair fee was very reasonable."

Customers say: True professional

"Kevin was able to come out the same day I called to inspect and replace a fluorescent light fixture that had gone bad. He gave me two options for replacement (install a similar fixture or go with an LED fixture). Since the fixture was in a recessed space above a sink that made it hard to change bulbs, I went with a LED replacement unit that requires no light bulbs. It was a little more, but well worth the extra cost. He was professional and I found his prices to be quite reasonable. So... I had him give me some quotes for other electrical projects I wanted done. He will be back next week to start those projects! I would recommend Kevin to anyone based on this experience."

"Had an electrician out to give me an estimate on replacing my electrical panel. Decided against replacing it because that wouldn't have solved my issue. My house was built in the 60's so it needs all new wiring. I just had him show me which outlets were on each of the channels so that I could spread out my devices that needed a lot of power, specifically my space heaters."

"This past winter we came to terms that our home needed an expensive upgrade. Electrical panels. My husband and I shopped around, like most we wanted quality at a great price. Sergio was very upfront with us, as a busy working family thats very important. During our consultation visit he was very patient with all of our questions. Also gave us good ideas for future upgrades. Home improvement are typically stressful, so having a patient and understanding professional helps the process so much easier."

FAQs for electrical wiring or panel upgrade projects in Ontario, CA

Yes, a licensed electrician is essential for this project. Running an electrical service from the road to your house involves connecting to utility power lines, complying with national and local electrical codes, and safely handling high-voltage systems. 

Licensed professionals understand proper wire sizing, grounding requirements, and voltage drop calculations needed for safe installation. Most jurisdictions require permits and inspections that only certified professionals can obtain. The safety risks and potential for property damage make this project inappropriate for DIY attempts.

Overhead installations are less expensive than underground options. For a 1000-foot run, overhead service costs between $8,000 and $15,000, while underground service ranges from $10,000 to $25,000. 

Overhead lines require less labor and fewer materials since they don't need trenching or conduit. However, underground lines offer better protection from weather events and aesthetic benefits. Your decision should balance your budget constraints with long-term reliability and visual preferences.

You might need to upgrade your electrical panel depending on your power requirements. If your existing panel cannot handle the additional load from the extended service, upgrading to a 200-amp service (costing $750 to $2,000) may be necessary. 

A licensed electrician can evaluate your current system and determine if an upgrade is required. Factors include what you'll be powering at the end of the line, existing electrical demand, and whether voltage drop over the distance will affect performance.

Running electric service from the road to a house requires electrical permits from your local building department, costing between $500 and $2,000 depending on your location. You may also need excavation permits for trenching work if installing an underground service. Your utility company will have its own application process for connecting to its grid. A licensed electrical contractor can handle all the necessary permit applications as part of their service, ensuring your installation meets all local code requirements.
