"From the beginning, the experience with Raymond was fantastic. He asked me for pictures of the current electrical panel, and with some additional information, he was able to provide an all-inclusive quote. He handled the permits and coordinated between the city and the power company. He was always very responsive and proactive. His team communicated clearly and was focused on getting every detail done right. I would hire Raymond in a heartbeat for any/all electrical work."

"We needed a NEMA 14-50 EV charger installed outdoors for an electric car, and got 3 quotes from Angie's List. Based on the 3 bids, it seemed certain we'd need a subpanel breaker box installed as our main breaker box was full and there were no empty slots to assign to the EV charger. However, only Tommy from Fairway offered up a potential solution within the existing breaker box, if they were able to source a hard to find quad breaker. It seemed unlikely, but would save a lot of hours (new box install / wiring under the house) and money. Sure enough, he source the part and made it happen. On top of that, they were professional and easy to work with. Highly recommend!"

"I got a few estimates to get more power out to my studio. Everyone quoted me about 4K to upgrade my panel and get dedicated line out to my studion. These guys were to only ones that looked for a better/more economical solution. I sent a pic of my panel and he remembered that I upgraded my kitchen a while back but noticed that my electric stove had it's own dedicated line. He asked me, did you convert to gas when you remodeled? I said yes and he said, great, we take the line that was dedicated to the stove and we use that. It saved me $1500 and it worked perfectly. I would absolutely hire again!"

"Alset Electric Company is ran by Eddie. Eddie is very professional, efficient and very detailed. In the month of June (2026), I had Eddie to install the RING..I chose the wire RING system with the cameras...Eddie and his crew was very efficient and cleaned the mess afterwards. I had Eddie to I install my address numbers thats lights up at night on my new stone wall for the house. Eddie did an excellent job. My neighbors are still paying me compliments. Here we are in July (2026), my dad asked Eddie to install new water sprinklers for the front yard and backyard. Eddie explained detailed what he done. Eddie is very affordable. If you want very good electrical work, Eddie is the one to call. I have used his services many times now and very satisfied. If you later have questions for any service he had done he will gladly talk to you and stop by if you ask him to."

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