"Very professional. Took as much time as needed to answer questions. Very good attention to detail. Even though a few more rods were needed than originally quoted, they stuck to their original quote price. No surprises. I would highly recommend this company."

"When I needed my electrical work done ASAP they were right there for me. They were very informative about what they were doing and didn t waste no time. I tried to get hold of electricians before them before I found out about home advisors but they were all to slow to respond. Some of the electricians didn t bother to show up so that s how I needed to find someone quick through home advisors. Thank you!"

"AES arrived pretty quickly after I called, had a reasonable price compared to the other electricians I contacted for the project, got the permit from the city, did the work well, got the inspection passed, and allowed us to restore power to our home. They were friendly and knowledgeable. I recommend calling them for your electrical project."

"Honest family business that does outstanding work, quickly? How can you top that. He explained a lot about lightning and the various dangers. Given my tall, metal roofed home in a wooded setting, I needed lightning protection. I've never had a problem in 23 years, until the past 3 months. The frequency and intensity of electrical storms is increasing. I had two close calls (at the expense of over $1,000 of electronics (that I had plugged into expensive surge protectors!) With something as important as lightning protection, go with experience. Red, White, and Blue has that!"

Electrical questions, answered by experts

Just like apples in a bunch, one bad outlet can cause other outlets to stop working. This is especially true if the outlets are connected in a series on the same circuit. When one outlet develops a fault, it can spread to every outlet downstream of the original.

It’s possible to distinguish a positive black wire from a negative black wire if you know what type of circuit the wires are in. If it’s an alternating current (AC), then black wires are positive. If it’s a direct current (DC), then black wires are negative. 

Sometimes, a circuit has two black wires. In that case, the positive black wire will be solid black while the negative black wire will have a white stripe on it. If you’re still unsure, you can use a multimeter to check.

The total cost to install a 120V outlet will depend on the type of outlet you choose, labor costs, and any customizations. Standard 120 volt outlets usually cost $3 to $5 each. But say, for example, you customize your 120V outlets with USB ports, you’ll end up paying a bit more at $13 to $22 per outlet. When it’s all said and done, you can expect to pay around $175 for each new 120V outlet and $125 each for replacement.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

Yes, gas dryers still need electricity. While their heating system relies solely on natural gas to produce the heat that dries your clothes, gas dryers use electricity to power the lights and display screens on their interface, turn on the drum, and power any automatic moisture sensors inside the unit.
