"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

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.

Choosing between 12- or 14-gauge wire for your house depends on the electrical requirements of the circuit. A 12-gauge wire is thicker and can handle more power, making it better suited for devices such as kitchen appliances, air conditioning units, or electric heaters.

A 14-gauge wire is thinner and can handle less electrical current than a 12-gauge wire. It's ideal for circuits with lower power requirements, such as lighting or general-purpose outlets in bedrooms or living rooms.

A gas stove doesn't always need a dedicated circuit. Unlike an electric range, which uses 240 volts and requires a 240-volt receptacle, a gas stove only uses 120 volts. In some cases, your electrician will need to replace the existing two-pole circuit breaker with a single-pole circuit breaker as well as swap out the existing 240-volt receptacle with a 120-volt replacement.

Yes. Like other trained specialists, electricians need to be licensed in their state of operation, and carry specific kinds of insurance required by that state, which usually includes general liability insurance and surety bonds. When choosing an electrician, always pay attention to these details, and avoid electricians who can’t offer proof. When it comes to wiring, you want experienced, trained pros doing the work.

The cost to upgrade an electrical panel ranges from $1,200 to $2,000, depending on the type of electrical panel you need and the size of your home. Amperage plays a central role in determining the cost, so calculate your home’s electrical load before purchasing. For example, a 100-amp and 400-amp panel vary widely in cost.
