"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

You can install a dimmer switch on almost any light as long as the switch, bulb, wiring, and wattage are compatible. Check what kind of light you have, the type of light bulb, and the total wattage of the bulbs to ensure your dimmer is a match. You’ll want to choose a non-neutral wire dimmer if you don't have neutral wiring. Homes built before 1985 that don't have updated electrical systems may not have neutral wiring.

If only half of your outlet works, there are usually two possible causes: faulty wiring or a half-hot outlet. The first thing you'll want to do is check the circuit breaker panel to ensure that it's not tripped. If your circuit breaker isn't tripped, turn off the electricity and inspect the wiring to see if anything has come loose or corroded. 

If you have a half-hot outlet, it means half of the outlet is controlled by a switch somewhere on the same circuit, which should be nearby. This is an intentional electrical design commonly found in rooms without overhead lights.

If you find the power cables for your appliances are too short, there are ways to extend them for the cost of just the extra wiring you need. Simply cut and strip your wires, solder them together, and cover them using heat shrink tubing. Not everyone has a soldering tool on hand, so if you’re looking to extend in a pinch, an extension cord, power bar, or surge protector can do the job just fine.

In general, 200 amps is enough for a house with a square footage of up to 1,800, or the average three-bedroom home. A 200-amp service allows your home to warm and cool itself while running multiple appliances at once. It's a good option for homes that have been extended, or after adding new appliances. 200-amp service is the current standard for homes, so in most cases, it will work for you.

Yes, placing an electrical panel in a bedroom is perfectly acceptable, so long as it meets other space requirements as indicated by OSHA and related agencies. When installed in a bedroom, electricians typically place it in the area directly behind the door swing. This method allows for easy access when conducting electrical panel repairs.
