"Project was upgrading service from 100 to 200 amps, installing new panel, new meter, grounding, and a new drop from the street. I gathered a number of quotes, and by far felt the most comfortable with Mr. Hyman. Plus the price for the job was in line with my expectations. The work was completed quickly and professionally. I'd definitely recommended using them."

"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!"

"not just professional efficient! Unbelievably fair priced literally less than half of what a major competitor on this site quoted using my own parts and my own wire! Just because there are any energy list doesn’t mean some people won’t try and rip you off and fools will pay it. Mr. NAGY is a professional and very ethical. I’d recommend hiring him again and again!"

"I found John Max Electric on Angi and couldn’t be happier with their service. They arrived promptly with a team of three skilled professionals who tackled each of the five electrical issues with precision and efficiency. What really stood out to me was their honesty—there was no price haggling, no upselling, and no push to sign up for a membership. I often feel anxious about hiring companies for repairs because of past experiences with unfair pricing or high-pressure tactics, but John Max Electric was a breath of fresh air. They were professional, fair, and top-notch in every way. If you’re looking for reliable and trustworthy electricians, I highly recommend John Max Electric. They’ve earned my trust and my business for any future electrical!"

"Ludwing did an amazing job! He installed a new light fixture in my home and what I appreciated the most was that he explained the connection to the wiring and how things work. This was very helpful because he corrected a job from a handyman who installed a light fixture that could have destroyed my home. He is a master of his craft. Not only will I use him for future projects but have also shared his contact with friends needing electronic assistance."

"Saul and Three Brothers services did a fantastic job upgrading our electrical panel. Saul explained everything throughout, agreed to do the work on a Saturday to accommodate our schedule, and was just generally very customer service oriented. We couldnâ t have asked for anything more. Highly recommend for electrical needs."
