"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.

"Rich showed up early and was very respectful of our wishes in terms of removing his shoes or putting on shoe covers.   He was very careful moving his equipment so as to not damage the walls or the stairs.  He covered everything that could be exposed while working.  He worked quickly and thoroughly.  He answered all my questions and even ran the negative ion machine in my son's room.  We would definitely hire them again (and we have!)"

"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

A light switch can stop working for several reasons. Typical causes include a blown fuse or tripped circuit breaker, both of which shut off power to the switch. Worn-out or faulty internal switch components can also prevent it from functioning properly. Loose or disconnected wiring within the switch or electrical box is another frequent issue. Additionally, switches may fail due to age, excessive use, or physical damage. In some cases, problems with the light fixture or bulb itself might be mistakenly attributed to the switch.

Grounding an electrical outlet can take as little as 30 minutes if you only need to replace the outlet or around two hours if you need to add a ground wire. However, more extensive electrical work will take longer, such as hiring an electrician to ground multiple outlets during the same service.

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.

Yes, but our analogy with the water hose doesn’t really work here. You see, electrical flow isn’t constant: It ebbs and flows like waves, coming in pulses of power. Hertz measures the rate of change in the flow of electricity, or how often it ebbs and flows. For example, 60Hz means that the electrons pulse through wiring 60 times per second. When they are pulsing, they’re in a brief retreat. Almost all United States equipment is rated for 60Hz.

A voltmeter measures the voltage of AC or DC electrical current. Unlike a multimeter, measuring voltage is a voltmeter’s only function. Voltage is the potential difference between two points within a circuit. Measuring voltage with a voltmeter can help identify wiring issues or determine whether a battery is dead.
