"Apollo responded quickly to a quote request. I described the job, provided some photos, and they were able to quote without a visit to the house, which was much appreciated. We scheduled the work for the next week. The communication during this period was very fast and smooth. The electricians arrived on time, we're very polite and professional, we reviewed the job once more, they completed the work, confirming with me the final location of new receptical before cutting started, and before I knew it the work was done. They cleaned up, we did final review of completed job, explanation of what to do in case there are questions or issues, invoice, out the door. Quite painless from end to end and I couldn't be more satisfied. Will hire again, absolutely."

"I am updating my rating for CA Electrical (Unfortunately Angi will not allow me to edit, so I am posting this as a new review). After posting my original review I was contacted by CA Electrical. The supervisor assured me that my experience was not their normal practice and that they normally made sure to call if there was a change of plans. I felt that they were earnest in trying to make things right, so I agreed to give them another chance. I ultimately decided to select them for my project to replace sub panel and install outlets. The crew was excellent and professional. They showed up on time, were professional and friendly, took extra care to ensure work spaces were left clean. Their workmanship was excellent and they did a great job of cleaning up some messy electrical wiring that had been there before. As an electrical engineer, I also appreciated the crews knowledge of code and ability to explain the technical side of the installation. I would use them again."

"The main complaint I have with Wooding Electric is that the repair was done at a rental property and when I spoke to the gal in the office I told her I wanted an estimate before the work was done. I never got a call to let me know how much the repair would be, and never got a call that the work was done. I had to call my tenant to see if the electrician had been there. I didn't find out how much the repair was going to be until I got the bill in the mail."

Electrical questions, answered by experts

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

No, it is not safe to use an outlet that sparked. A spark from an outlet could indicate a short circuit, loose or frayed wiring, or other serious damage. Continuing to use an outlet that sparks can increase the risk of electrical shock, electrical fires, and other hazards. It's important to turn off the power to the outlet at the circuit breaker if possible and avoid using the outlet until a licensed electrician has inspected and repaired it.

DIY is not recommended for commercial settings due to safety regulations. Hire licensed professionals for compliance.

For more complex electrical projects, it’s often most efficient and cost-effective to hire an electrician rather than trying to figure it out yourself (and risking electrical problems). Electricians know exactly what a project requires, and can often find supplies or parts for cheaper than the average homeowner. That can save money compared to going it alone.

Yes, the National Electrical Code reviews household codes every three years. However, that doesn’t always mean that kitchen counter outlet requirements will change, but it does allow room for professionals to make updates. That’s why many older kitchens are no longer code-compliant thanks to changing rules for amperage, GFCI protection, and more.
