"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."

"Ahmed is great. Did a great job to upgrade my electrical main panel with very reasonable price. He actually corrected the error made by the AC installer without I asked him to do so. Every professional! Highly recommended"

"Responded immediately to our inquiry. Sent their guy, Israel, for inspection. Since the job was not complicated, we had him complete the job. He was very respectful, told us the problem, proceeded to complete the job. I would highly recommend CA Electrical Group."

"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

Incorrectly wiring a single-pole switch results in the connected light or device not turning on or tripping the circuit breaker. Although it doesn't matter which terminal the hot wire and the load wire connect to, mixing up a circuit wire with a ground or having loose connections can prevent the switch from working. 

Replacing the panel itself takes four to eight hours of work by a professional. However, if associated wiring and related components also require replacement, the labor time increases to 20 to 30 hours. Your electrician can speed up the process by bringing in a team of pros to handle ancillary tasks.

Yes, dehumidifiers use a lot of electricity. However, proper humidity also means your home’s temperature remains more stable, thus lowering heating and air conditioning bills. The good news is you shouldn’t need to use a dehumidifier more than a few months per year, so the energy costs won’t be as noticeable as other larger appliances.

Upgrading your electrical system can save you money on your monthly utility bills by powering your home more efficiently. Electrification nonprofit Rewiring America estimates that a household could save $1,800 per year on energy bills by upgrading to a modern electric heat pump, switching to a heat pump for their water, installing solar panels on the roof, and converting to an electric vehicle.

Often, you can add extra breakers to an electrical panel. A new breaker can help with new appliance needs, and it’s a common solution when finishing an attic or basement. However, adding extra breakers can’t bring in more amps to your house, so you still need enough amp service to power everything in total.
