"Jarvis Electric did all of the electric for our new build and has come back to add additional items that we have added since we have been in the home. Super responsive and quick to complete all requested work. Top notch service. Extremely reasonable price. I appreciate that they always keep a clean worksite and never leave a mess, even if coming back the next day to finish a job. I have not only used them for my home but referred them to my mom and dad as well when they needed work done. Great company with great people and really easy to deal with. They truly went above and beyond."

"Ron, our installer, was absolutely wonderful! He arrived on time, was pleasant, and efficient. Ron worked on New Year's Eve, was close to finishing his job, but could have stretched it into the next day. Rather than leaving us "in the dark," he worked until the job was completed that day. We appreciate all the hard work from Ron! We definitely recommend Reinhold for any of your electric needs!"

"I was pleased with the installation of the lightning rods--communication was great and the work was done quickly. What I wasn't happy with is he quoted me a price that was less then my actual bill was BUT the price was still less then two other contractors bids."

Customers say: Quick response

"Tom from Synergy did the bid for under cabinet lighting install, however sent someone else to do the job. Originally discussed with Tom that he would use a regular converter box inside the cabinet and place a dimmer switch on the wall, but the other guy he sent wasn't aware of this and placed the dimmer converter in the cabinet. This has resulted in us having to use the dimmer switch inside the cabinet instead of on a wall switch -- not what I requested. Also, I discussed with Tom installing an additional outlet in our kitchen during the bid process. After he left I noticed he did not include that on the written bid. The guy he sent didn't know about it either. The outlet was installed however. Overall, I was charged $95 additional over the bid and didn't get exactly what I wanted in regard to the dimmer switch for under cabinet lighting. Both electricians were very nice and professional, but there was definitely a communication problem in regard to the installation of the under cabinet lighting. Perhaps I should have clarified the issue more strongly, or perhaps I didn't understand. Either way, I'm happy with the lighting overall, but not 100%."

Electrical FAQs, answered by experts

While the line can't be removed, a pro can place a cap on the end to stop leaks. Contact a pro for a service call and speak with them about the related costs of either capping or removing the line altogether. Capping a gas line will cost between $75 and $150 while removing it will start at $250.

There are several indicators that a single-pole switch is bad: the switch is warm or hot to the touch, sparks are sometimes present when turning the switch on or off, you hear a buzzing sound or other weird noise coming from the switch, the connected light flickers when you turn on the switch, and the light doesn't turn on at all with the switch. If you notice any of these, replace the switch or call a pro straight away.

If you need to run a wire from the meter to the breaker box, start by turning off the power using the main switch to avoid injury risks from live wires. Then, locate the ground wire from your meter and connect it to the ground bar of the breaker box. Connect the neutral wire using the same method to improve your circuit efficiency.

Next, locate the hot wires running from the main switch to the meter. To connect them to the correct terminals from meter to breaker, unscrew the nuts of the breaker hotwire terminals, insert the positive hotwire, and ensure it’s firmly attached. Finally, secure the wires with electrical tape and wire tie cables before re-securing your breaker box. Keep in mind that this process can be dangerous, so don’t hesitate to hire a local electrician.

A GFCI outlet is a type of electrical outlet that monitors the electricity flowing through the circuit and shuts off power immediately when it detects a loss or acceleration of current. They are particularly important in areas that may come in contact with water, which is why they're most common in kitchens, bathrooms, laundry rooms, and garages.

A GFCI outlet is easy to identify. It features two buttons on the face that read “TEST” and “RESET.” Sometimes, the “RESET” button is red. These are positioned in the center of the two three-prong plug-in slots you see on a regular outlet. Some also feature a green light to indicate when the outlet is working, changing to red when there is a problem.
