"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

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

Yes—if a breaker is old or damaged, it might not be able to detect power surges or electrical overload. If that happens, the breaker won’t trip. Instead, it will begin to overheat, putting your electrical system at risk of fire or total electrical failure. Circuit breakers don’t last forever, so you can proactively replace old or damaged breakers before they stop working.

Motion sensors are actually an eco-friendly option and don’t use as much electricity compared to other lighting sources. Motion sensor lights are always on “standby,” which requires a phantom source of power at all times, but for most sensor light models, this is only a small amount of electricity—typically around one watt of power.

That depends on your setup. If a circuit breaker already has GFCI protection, then everything connected to that specific circuit is being monitored. You don’t need additional GFCI outlets on that breaker.

However, if the breaker is not GFCI, then you should have GFCI receptacles for at-risk outlets nearby water sources, because they are not receiving protection. Breakers in a breaker box can vary between GFCI and non-GFCI. Look for GFCI labels on the breaker or try to find the breaker model number to look it up if you aren’t sure.

You should never plug a normal 120v appliance into a special 240v outlet, as it can quickly burn out the appliance. This will cause irreparable damage to the appliance and, in worse case scenarios, cause damage to your circuit breaker. Check your appliance’s rating before plugging it into a 220v outlet to avoid electrical disaster.
