We hired Alternating Currents to install an electrical box and mount a 55" TV above our fireplace. Marty was very professional and clear about the services to be performed and expectations. The crew was courteous and efficient, arriving on time and they ensured that the job was done exactly as requested.

I have an older home with an electrical issue and the staff of Alternating Currents came up with three creative and decorative solutions for me to chose from - that is truly appreciated services.

Kevin C.

Installed sensor for outdoor lights so they will turn on automatically in low-light situations; installed overhead light; adjusted a few outlets; gave estimate and advice on whole-house surge protector. We have used Alternating Currents multiple times now, and they are always prompt, professional, fair in price, and do excellent work. We couldn't be more pleased.
