"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

No, because amps and volts measure very different things. However, you can use basic equations to find amps or volts by using data about one of the measurements to calculate the other.

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. 

A C-wire is typically blue, but don’t rely on colors to find which wire is which when it comes to thermostat wires. The C-wire may also be black, brown, or purple. Instead, if you’re looking for the C-wire, look at the thermostat panel for a wire connecting to “terminal C,” or call in a pro to help you look for a C-wire.

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.

A light switch should be at least 2 inches from the edge of the trim of a door. The location of wall studs will often help determine where to put the light switch by your doorway, and in most cases, wall studs make it impossible to install the switch closer than 2 inches. When possible, try to keep the switch within arm’s length of the entryway.
