"Greenleaf Electric: very professional, assessed needs quickly. Installation of a ChargePoint home EV done after the local inspector required electrical upgrades for the main panel, changes to insure the house was up to code, including placement of a new mast. Other improvements done to bring my 1965 era home up to date. Greenleaf Electric is exceptional. Very pleased with the staff brought in to assist, the two inspectors from Frederick County, also Potomac Edison - all were professional. Also replaced security lights, installed Ring doorbell and cameras, installed new Carriage lights for the garage and front door. Just awesome! Thank you!"

"Murphy Family Electric is an awesome company with very competent technicians and reasonable rates. They make the whole process pretty straightforward. I had used them to get my Tesla charger in 2018 (Cost: $799 including material). I was so impressed with their work that when I had a complex electrical job - installing a new 120v outlet requiring a new wire from the circuit breaker - I did not get any quotes but just booked them. That job was done very professionally as well (Cost: $949). Fast forward to Mar 2025, my tesla charger had problems with over heating and intermittent power loss. I called Murphy Family Electric and they sent a technician the same day who came and adjusted/cleaned the connections and spent 30 mins fixing the problem. And to my surprise the company did not even charge me anything for this. So on top of everything else you can add absolutely fantastic customer service to their list of attributes."

"Thank you James Im, Antonio and crew for an amazing experience and a job well done! It is rare these days to find a home improvement company that you can trust from beginning to end. AHC staff and representatives ensured that every detail from estimates, to coordinating delivery of materials and quality control of installation was performed to the highest standards and exactly on time. James and Antonio/crew were attentive to our every question and concern, and in the end made the experience with AHC a memorable one worthy of the highest level recommendation. Bottom line: If you choose any other roof replacement contractor - you will be making a mistake!"

"Larry and his crew upgraded our under cabinet lighting with new LED lighting, and specialized outlet. Not only was our home and its contents treated as if they lived here, the job was done professionally. So much so, that the only issue we had was when the switch/outlet face plate screws came loose. I didn’t even bother calling Larry, I tightened them myself. The lighting is on, literally 24 hours per day since the install, with zero issues. Love these guys."

"Our furnace finally bit the dust after 25 years of faithful service. I had TriState do several small repairs and maintenance on it over the years, and they always did a good job. So, when the last service rep told me it was finally beyond repair, we consulted with Comfort Specialist, Darren, who isn't just a salesman, but previously installed and repaired HVAC systems. He took lots of measurements, inspected the old unit and the runs to the outside and upstairs. He took his time making calculations and offered us several options on a new system. TriState uses Daikin furnaces, which are rated in the top 5 furnaces for dependability and efficiency. The price, I thought, compared to my two other neighbors, who also recently purchased new systems, was even lower than I thought it going to be. In fact, my neighbors paid more (by thousands) and have a smaller square footage footprint than my house. We've had the unit now for over a month, and so far, it's great. It is a one-zone system, yet the upstairs will only vary by one or two degrees. This is much better than the old unit. We're hoping this small variance in temperature will also apply when the AC is on in the summer. The installers were very professional, arrived on time and completed the work in a timely manner. I would definitely use TriState again, and will rely on them whenever I need service."

"Lou showed up on time for the quote and won us over. We scheduled him to do the actual work and he was not the best at keeping appointments or notifying us if he could not make it. The work finally got done about two weeks after the original appointment. He was scheduled to return for some finishing details and final electrical inspection. Again several reschedules (he had not even been paid yet which really made me wonder. I am sure he was not going to work for free). Had to leave messages that normally went un-returned. He did finally return for the last details but still no final inspection (we did pay him on this visit). Began having an issue with one breaker. Scheduled him to check it. No show. Left messages, no return calls. So here we are a couple months after beginning this project, mostly happy with the work that was done but not happy about scheduling issues, lack of follow up and still no final inspection."

FAQs for electrical for home addition or remodel installation projects in Unionville, MD

Because installing coax outlets involves working around existing electrical wiring and confirming proper grounding, many homeowners prefer to hire a licensed electrician. A professional completes the work safely, secures the line behind the wall, and ensures the installation meets local code, which reduces the risk of damage or future repairs.

You still need a coaxial outlet for most cable-based internet services. The modem draws its signal from a cable line that terminates at a dedicated wall jack. Once the modem is online, your Wi-Fi router can broadcast the signal throughout the home, so the outlet’s location doesn’t affect wireless performance. If an existing jack is damaged or in an inconvenient spot, an electrician can move it or install a new one to maintain a strong, reliable connection.

Coaxial cable loses signal strength the farther it runs. A 50-foot length introduces noticeable loss, and a 100-foot stretch can drop the signal by roughly 30%. A weaker signal can result in a fuzzy picture or slower internet speeds. To maintain high performance, limit cable length whenever possible, select the correct cable grade, and route it efficiently. If your layout demands an exceptionally long run, an electrician can install an inline amplifier to boost the signal and maintain picture or data quality.
