"Jorge and his crew did a great job removing an old patio ceiling fan and light fixtures and replacing both and relocating placement of the lights. In addition, they removed two old security systems and installed a new outdoor electrical outlet. They responding to my request for a bid quickly and completed the work within less than a week of my request. I would definitely hire them again."

"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!"

"The whole process, from estimate to follow-up service, was superb. There was an issue with the installed timer. A simple request and the replacement was scheduled for replacement within a week at no charge. A request for an upgrade was also done quickly for a small charge. I highly recommend Martin!"

"Contacted JVEC for an evaluation of work issues related to a kitchen remodeling contractor. The evaluation and review were timely, thorough, and provided me the tools to discuss the shortcomings and necessary corrections with the kitchen contractor. As a result of the help provided by JVEC, the corrections were made at little additional cost. I would highly recommend JVEC and they will be my first call for any future electrical work."

"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."

"Very satisfied with upgrading a 100amp residential electrical panel to 200amp. Benjamin and his crew came out to review a 40+ year old panel and his bid laid out everything he thought needed to be done. His bid was similar/competitive with the other two I received, but as with anything like this, some extra costs did materialize after discussions with Edison and City of Long Beach; he explained all of these and got my sign off on everything he did/added, and at the end he kept the extra costs as low as possible. Benjamin’s communication was great and he tried to explain everything to me - the novice. During the “rough inspection” the inspector said “this is probably the cleanest and most organized residential panel project I’ve ever seen”. They also did a nice job of covering the old service mast and panel/meter box and cleaning up after the project. Orozco's will be coming back for some other work inside my house and I will probably eventually bring them back for some upgrades"

FAQs for electrical for home addition or remodel installation projects in Diamond Bar, CA

Because installing coax outlets involves working around existing electrical wiring and confirming proper grounding, many homeowners prefer to hire a licensed electrician. A professional completes the work safely, secures the line behind the wall, and ensures the installation meets local code, which reduces the risk of damage or future repairs.

You still need a coaxial outlet for most cable-based internet services. The modem draws its signal from a cable line that terminates at a dedicated wall jack. Once the modem is online, your Wi-Fi router can broadcast the signal throughout the home, so the outlet’s location doesn’t affect wireless performance. If an existing jack is damaged or in an inconvenient spot, an electrician can move it or install a new one to maintain a strong, reliable connection.

Coaxial cable loses signal strength the farther it runs. A 50-foot length introduces noticeable loss, and a 100-foot stretch can drop the signal by roughly 30%. A weaker signal can result in a fuzzy picture or slower internet speeds. To maintain high performance, limit cable length whenever possible, select the correct cable grade, and route it efficiently. If your layout demands an exceptionally long run, an electrician can install an inline amplifier to boost the signal and maintain picture or data quality.
