"This company is obviously nationwide and hires local contractors.  I trusted Agies List that all contractors are licensed, bonded and have background checks.  This person was a handyman and not qualified to wall mount, conceal wires, add electrical outlet.  He  spend five hours in my home, for a job that should have taken two hours and left the area in a disaster.  The TV was hung close to the ceiling, the wires were hanging down from the TV, and the receiver was sitting on top of a plaster box because the cord was too short.  He was obviously not qualified to install TV wall mounts.  I have photos.    As soon as he left, I called Best Buy Geek Squad.  They were able to come out the next day and mount the TV professionally.  I have used the geek squad in Virginia and they are highly qualified.  They charge more than this nationwide company but you get what you pay for.  I called Angies List the day after the disaster and said i did not want to rate this company but I wanted to talk to a manager. No one called me to apologize. I have cancelled my membership.  Do not use this company unless you can be assured that the local contractor is qualified and is licensed.  You should never let anyone into your home that has not had background checks.

"There were many things wrong in my computer (my fault and letting grandchildren on computer) Robert was so helpful, gave me many good instructions to keep everything safe, which I have written down, feel like I have a new computer. He was so excellent and experienced, took his time and was meticulous about what needed to be done. He was a pleasure to work with and I will use this company again! Linda Disy"

Electrical questions, answered by experts

You should never use a plug with burn marks because it can cause a fire or even an electrical shock. The burn marks could be caused by a dangerous underlying electrical problem, so it’s important to call a qualified electrician right away. 

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.

Black is the standard color for hot wires, which transfer electricity to your outlets and switches. Red wires are also hot wires. White (and sometimes gray) wires are considered neutral, delivering power back to the panel. Finally, green wires, which are sometimes bare copper, are ground wires, used to ground an electrical circuit and prevent electrocution.

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 lifespan of an average breaker box is 25 to 40 years, depending on the type and electrical events that occur in your home. Frequent power outages or surges can cause the breaker box’s lifespan to shorten. Maintain this essential electrical component by avoiding turning it off and inspecting it regularly for signs of damage.
