Amazing company with great communication and staff. We hired them to do a “heavy up” to install a 200 amp panel. The technicians, Kevin and Jeremy, were punctual, friendly, and efficient. I reached out to William several times with additional questions and he was helpful and thorough each time. All in all, I would definitely do business with these guys again. The price was right and even more importantly, the quality and professionalism were there from start to finish. Thanks, team.

i am pleased to give Hyman Electrical a top rating for the exceptional service I was provided. I had a very unique electrical problem and Bill was able in one phone call to guide me to a solution that completely solve the problem., which turned out to be Pepco‘s burden. Though he did not do any work his timely advice was invaluable. And furthermore he wouldn’t send me an invoice as I requested.. I will use this firm for any electrical need I have going forward.

Outstanding work by William G. Hyman Electrical Contracting. I am impressed with the professionalism, attention to detail and technical skill. Jeremy and his partner (forgot his name) expertly diagnosed and repaired an issue with old wiring in a crowded electrical box and associated 3-way switch. They also described a safety and building code issue with an outdated electrical panel with Pushmatic circuit breakers. As a result I had the panel and replaced and upgraded my service which went smoothly, timely and efficiently. If you want to be assured the job is done properly and professionally and will pass the County Inspection then this is... Outstanding work by William G. Hyman Electrical Contracting.

We were referred to Hyman Electric by friends. We saw the glowing reviews online and Bill was extremely informative when we first spoke. We had been in our new house for only a few months. It was built in 1952 and rehabbed/expanded in 2006. Dual zone HVAC/heat pumps were added in 2015, a generator in 2016 and we were effectively bursting at the seams power-wise wanting to add an electric pool heater when Bill recommended we “heavy up” from 200 to 400 amp service.

Dual zone HVAC/heat pumps were added in 2015, a generator in 2016 and we were effectively bursting at the seams power-wise wanting to add an electric pool heater when Bill recommended we “heavy up” from 200 to 400 amp service. We initially had them upgrade a circuit for our new electric induction oven, then Bill started the planning for the “heavy up”. Pepco did a field inspection then Bill wrote up the contract. Jeremy and Kevin were there right away and did the inside circuit panel work as well as the outside meter panel and connection work in a couple of days, and they were able to run our generator which eliminated a loss of power while they did their work. The County inspector commented on their great work. And Bill coordinated all the steps from initiating and managing the process with Pepco, scheduling the County inspection, to the cutover with Pepco, which Bill and crew’s wiring installation allowed us to use the generator and avoid a long power outage. Superb work overall. I thank Bill for the power up suggestion and wholly recommend that procedure and having Bill and his crew perform the job!
