"My reason for wanting to volunteer a review is due to Kolb Electric and how they responded to my request.....wanting and needing my porch to have light....I purchased an Outdoor Ceiling Fan.....w/light. I needed it installed by 10/31/14 and I just purchased the Ceiling Fan on Monday 27th......so I used Angie's to request a couple of companies to see who could get the job done by Friday. 
Immediately I received a response back from Kolb Electronic instructing me to call so I can set up the time for Friday! 
It get(s) better.....after calling to set up an appointment at a rate of $195 for the 1/2 hour and $45 every 1/2 hour after that.....
I received another call from a project manager who explained by me being an Angie's List member and the price I was quoted is wrong....and the new rate would be $85 for an hour. Too good to be true right......but Friday came and there was Kirk at my door promptly at 8:45am.....ready to work. Totally professional and efficient....explained everything to me about the type of Ceiling Fan
I had....and the functions of it. 
Bottom line....incredible customer service and but also discovering the Real Benefits of being an Angie's Member just took it to another level.....this was my first year test with Angie's List....and honestly I was planning on cancelling my membership after my year was up....but with this recent situation with Kolb Electric....no cancellation here. 
Thank you Kolb Electric and Thank you Angie!!!
Mr. Francis Weaver

Customers say: Quality work

"From start to finish, Long Electric had our backs. We didn't have to hire sub-contractors or to obtain permits -- Long Electric took care of everything. Our go-to person in the main office, Melissa, answered all of our questions and kept us apprised of everything we needed to know. Everyone we had contact with throughout the installation project treated us with the utmost in professionalism. Not only will I call upon them for future electrical needs, I have referred Long Electric to a friend who is also interested in a whole house generator."

"I had a wonderful experience with Electrical Connections. My project ended up being much larger than I anticipated it would be and they were excellent at explaining everything and helping me understand what needed to be done. Customer service was top notch and clearly a priority for everyone I talked to from the scheduler to the owner of the company. Brian was excellent and stayed until the job was done even though it made an extra long day for him. Highly recommended!"

"Our existing generator died. James diagnosed the problem and gave us a few options to repair or replace it. We chose to replace it. James handled everything, from getting and installing the new generator to electrical and fuel (propane) connections. We have asked him to schedule us for the annual maintenance on the machine. We are pleased, though we haven't lost power since it was installed, LOL."

Electrical FAQs, answered by experts

A C-wire connects your thermostat to your household heating and cooling system to provide continuous 24V power. The furnace's transformer converts household electrical current into this low-voltage power to operate the HVAC system's circuitry. In most configurations, the C-wire connects to the terminals labeled "C" on both the furnace's low-voltage terminal block and the thermostat. In some cases, if a dedicated C terminal is unavailable, the C-wire can be connected to the "G" (fan) terminal at the furnace.

No, it doesn’t matter which of the two wires goes on each of the two switch terminals. Just be sure to put the ground wire in the correct terminal. The ground wire is either green, bare copper, or green with a yellow stripe. The other wires are hot wires and are typically black. They can be used interchangeably.

Multiple wire sizes are used for residential electrical purposes. While the most common sizes used in homes are 14 and 12 gauge, some appliances, such as stoves, electric water heaters, central air units, etc., may use larger gauge wire to accommodate their larger amperage. Typically, larger appliances require 10-, 8-, or 6-gauge wires.

There are a few ways to reduce your electricity bills if you use window AC units to keep cool. Set the unit temperature at least 1 degree higher than it is currently to reduce costs. Keep the unit clean for it to run efficiently. You may want to hire a window AC specialist near you to inspect the unit once a year and keep it in tip-top shape.

Thankfully, LED lights use less electricity than incandescent lights, meaning you won’t spend as much on utility bills by using these light strips. Each 5-meter LED light strip will cost about $3 per year on your energy bill.
