"Lowest price among multiple quotes and significantly more attention to detail and the least visible and least intrusive installation of new wiring from the existing panel. Would definitely recommend and use Mark H. Anderson Electrical Services again!"

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!"

"We had five different things for Lou to fix, including a chandelier that needed to be lowered and made level. Lou rounded the oval links in the chain that held the chandelier and that made it level for the first time! He figured out why a ceiling fan was making noise and why another one wasn’t working at all. He also replaced part of our electric panel which had somehow gotten water inside and was corroded. We didn’t have the right part to change lights in our Faber stove hood, but Lou did, and quickly replaced them for us. We were really pleased with how knowledgeable and competent our electrician was and plan to call him again if we have any more electrical problems."

"I needed a dedicated 20amp circuit and outside outlet installed to my patio. Maitiai arrived on time, was friendly/professional, and completed the agreed upon work. He filed for the appropriate permit with the City of Frederick, and helped schedule the inspection which passed without issue. I would have no hesitation contracting with him again in the future."

Electrical questions, answered by experts

Yes, if something sparks when you plug it in or turn it on, it's important to unplug it immediately. A spark from an electrical appliance or device could indicate a short circuit, damaged wiring, or other electrical problems that could cause electrical fires or electrical shock. By unplugging the appliance, you can reduce the risk of electrical hazards and prevent damage to the device itself. It's important to avoid using the appliance until it has been inspected and repaired by a licensed professional to ensure that it’s safe to use.

Yes, in a new home, ground wires are mandatory. Some older homes may not be grounded, but if you decide to renovate, you will need to have your electricity grounded at that time. Remember, grounding helps keep everyone in your home safe from sudden electrical surges. It’s best to hire an electrician to inspect and work with your home’s wiring.

A multimeter does not measure frequency, charge, inductance, and other electrical quantities. Instead, it measures voltage (AC and DC), current, and resistance.

Electric bills tend to be lower in spring and fall because people use less electricity during these seasons. Milder temperatures allow for less use of heating and cooling, unlike during winter and summer, which usually bring more extreme temperatures.

Smart light switches are designed to be compatible with most lights and traditional home wiring, but there are several key factors to check. First, verify your home's wiring, as some smart switches require a neutral wire to operate, which may not be present in older houses (often built before 1985). Always check the wiring requirements for the specific model you choose. Second, consider your light bulbs; while smart switches work with almost any light, using a dimming feature requires dimmable bulbs, such as dimmable LEDs. Finally, ensure you have the necessary network connection. Most smart switches need a Wi-Fi connection for remote control, but some older models might use other standards like ZigBee, which would require a compatible hub.
