"James came out to price install of a box to plug in my portable generator. After we started talking and me asking questions James was able to give me an outstanding price on a whole house Generac generator with panel upgrade and included a whole house surge protector. They ran into additional costs with running the gas line but James kept to his word and honored the original price! The crew were professional and proficient in their work! Marcie was outstanding with communication and explaining any questions I had! I would definitely recommend this company and would use J&M for any future electrical needs!"

"Tolliver Electrical did a commercial job for me at Fleetpride. (a heavy duty truck parts store) The company did an excellent job in completing the electrical work before the staff reported back to work the following morning. Tolliver Electrical is the only electrical company that I call on for all my electrical needs"

"Called and was scheduled for the appointment 2 days later. They called before coming over and actually arrived faster than expected. He was able to determine what was wrong with the door bells and fixed them quickly. He said he would have to trouble shoot the light fixture but suggested changing all 3 of the light bulbs. Well, that was all that was needed. Color me embarrassed. He asked if there was anything else he should look at, which was very nice. We will call them for any future electrical needs."

Electrical questions, answered by experts

The process of hiring a reliable electrician begins by searching for local professionals and verifying that they hold a master electrician certification and the proper licensing for your area. After that, you should read through reviews from past customers to see the kind of service you can expect from the contractor, as well as look at the Better Business Bureau’s (BBB) website to check for a history of company complaints. You can also ask for customer references to make sure you’re choosing a reputable professional.

Most people don’t think twice when using loose outlets, but they are a safety hazard. Loose outlets can cause issues with the flow of electricity in your home, resulting in electricity jumping from one connection point to another. When this happens, it can cause a spark that could start an electrical fire in your walls.

Choosing a unit with higher BTUs can use more electricity if the BTUs are more than what’s necessary for your room size. However, choosing an AC with BTUs that match the size of your room or house, your unit will cool your space efficiently. On the flip side, choosing a system with not enough BTUs can cause the system to work harder to try to cool the space, leading to more electricity consumption and higher energy bills.

How many string lights can be on one outlet depends on a number of varying factors, including the total wattage of your circuit, the type of lights, the energy needs of the lights, and cord specifications. It’s better to play it safe here to protect your circuit, so figure out the max wattage of your circuit, compare that to the lights, and move on from there. Generally speaking, LED string lights require less energy than incandescent bulbs, translating to a higher number of lights per circuit. 

When installing an outdoor outlet, it's important to proceed with caution. Unless you have the necessary training and licensure, it's not recommended to attempt this DIY. First, choose a suitable location. Make sure that the area can accommodate the outlet without overloading the circuit. You'll also need to ensure that your project complies with building codes. Next, turn off the power to the circuit, then install and wire the outlet according to the manufacturer's instructions. Once the outlet is in place, test it. Lastly, be sure to use a cover that will protect it from moisture and other weather-related damage.
