"The two service men who came to complete our "electrician for a day" deal where just flat out awesome. We gave them a fairly long list of items that we wanted done that was quite varied in nature (replacing electrical outlets, installing dimmer switches, exhaust fan timers, re-wiring a light switch, installing a light fixture, installing TV on the wall, and more). They worked through the list quickly and efficiently, explained things about our electrical system along the way (which was very helpful) and were exceptionally courteous and professional. They also worked very well as a team, dividing and conquering all of the items on our list. Recommend them without reservation."

"Everything about Able Electrical Services service was superb! I was in a jam, and Able Electrical Services came to the rescue. Both of the mechanics that assisted were excellent. Russell Ridgway was the primary mechanic and he was amazing! His work is superior and he exceeded my expectations every step of the way. For example, I needed electrical outlets to connect install a wet bar. He measured the wet bar and installed the outlets exactly where they were needed and ensured sufficient power was added to accommodate a kegerator and mini-frigs. I highly recommend Able Electrical Services and hope I never need to use any other electrician."

"I found John Max Electric on Angi and couldn’t be happier with their service. They arrived promptly with a team of three skilled professionals who tackled each of the five electrical issues with precision and efficiency. What really stood out to me was their honesty—there was no price haggling, no upselling, and no push to sign up for a membership. I often feel anxious about hiring companies for repairs because of past experiences with unfair pricing or high-pressure tactics, but John Max Electric was a breath of fresh air. They were professional, fair, and top-notch in every way. If you’re looking for reliable and trustworthy electricians, I highly recommend John Max Electric. They’ve earned my trust and my business for any future electrical!"

Electrical questions, answered by experts

A ceiling light will usually have two or three wires: black, white, and sometimes green. Black wires are positive, or hot, while white wires are negative, or neutral. The green wire is the grounding wire. 

When you’re wiring the light, connect black to black, white to white, and green to the grounding screw.

Yes, you must use the proper wire nut that fits your wire gauge. Using a wire nut that’s too big or too small can cause your connection to fail, short circuit, or disconnect entirely. Ensuring that you have the proper wire nut size will guarantee that your connection lasts as long as possible.

An AC disconnect, also known as a switch box or fuse box, is a safety switch that allows the AC’s electrical supply to be turned off from the outside, usually done by a mechanical contractor coming to work on your unit. The box is protected from the weather by a cover or may be designed as a pull-out unit. Your local code determines where the AC disconnect must be mounted, but it's usually close to your outdoor AC unit.

You can distinguish the amplitude and voltage of most outlets by looking at the shape and positioning of the holes. Other features like buttons, switches, and USB ports help identify electric outlets, too. Use labeled images, like the ones we’ve included above, to cross-reference with your outlets.

A 100 amp electrical service panel can't convert into a 200 amp panel simply by switching the breakers or adding circuits. Upgrading from 100 to 200 amps typically requires replacing the circuit box and updating the electrical service coming into the house. Your electrician will handle the details of the project to ensure a safe and thorough installation.
