"As usual with Garafano Electric, everything went fine -- way more than fine, actually. We have used them for years on various upgrades to our 1920's mediterranean home. William, the owner, is great about explaining our options and always finds the best and most efficient way to work within the confines of an older two-story duplex on a sloped lot that has serious access issues. Pricing is fair, they have never failed to show up on the appointed day, and on time, and complete the job as agreed. They have never disappointed for over 20 years, and I recommend them without hesitation!"

"I called them about an electrical panel upgrade and they responded immediately. They looked at some pictures and heard our situation, did their calculations, and it turns out that we didn't need an electrical panel upgrade. Other companies might have done the calculations but gone along with us thinking we needed work done to get some business, but these guys were honest and upfront and ended up saving us a good amount of money."

"I hired Ken Johnson (Johnson Electric) to correct a number of electrical problems which were identified in a pre-sale home inspection. Among these was a replacement of an unsafe old circuit panel, all new power outlets, conduits and receptacles. Ken provided a quote which was very reasonable. Actual work was performed by two technicians. They arrived on time, completed the job the same day, and left the site in pristine conditioner. We were very satisfied with their work and based on my experience I am happy to recommend Johnson Electric for quality electrical projects in your residence."

"Kevin did a fantastic job on our panel upgrade. He arrived on time and quickly got to whipping up a quote on the spot. He gave us several options that were all reasonable and made sense such as a basic level panel swap and a higher tier panel with lots of expandability including solar-ready. He also gave some additional add-on options such as grounding rods and stucco repair which was greatly appreciated although ultimately we did not use. Not once did Kevin try to pressure us into purchasing these additional add-ons which is greatly appreciated. Kevin is a respectful and does not get pushy. He arrived in a very professional truck with an additional electrician. Together they were able to get all the work done within one day with minimal disruption. I also really appreciate how clean the stucco breakout was as I have seen other electricians just take a sledgehammer and really leave the stucco in bad shape. I would definitely recommend Kevin and I will be reaching out to him for any future work."

"I reached out to Electric Zone for a few items we wanted in our home; a couple outlets installed in our closets and assistance in wiring a new pendant light. Haik from Electric Zone called us and arranged to come by the same day we reached out so that he could come by and provide an estimate, the price was fair so we decided to move forward with them. When Haik and his coworker arrived they discussed every step with us before proceeding, we were very happy with the options and works provided. Definitely recommend, we will be reaching out to Electric Zone again if we need more work in the future."

"MJ services was a professional and reliable business. They upgraded my electrical panel to 200. He obtained permits from the city and everything easily passed during inspection. His prices were reasonable and he even installed my EV Tesla charger. Would recommend him to anyone."

FAQs for electrical wiring or panel upgrade projects in Pomona, 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.
