Their electrician was great. Honest and able to explain what's-what in laymen's terms. Highly recommend.

Re wire, lights, found buried box, outdoor lights. Great.

I used them to install some can lights and run a new line to my pump room in the basement. I quoted out a few other places, and AC was the lowest by $100. Office staff and electricians were extremely professional all around. They were honest too. Told me I didn't need a new receptacle in my basement, but I did it anyway for my own reasons. Would recommend them to anyone.

We live in a 90-year-old house and over the last 20 years have had a lot of work done, and this company has been the best. Marty did a great job providing us a detailed bid since we had so much work to be done. The electricians worked efficiently and full days. They were great at explaining our options in our 90-year-old house. Once done, they cleaned up, and I would have never known they were here! I would highly recommend them.

I contacted Alternating Currents about an outdoor lighting issue. They were very quick to respond and asked a few questions. Marty called me with a followup and suggested I check something manually as it is often the root of similar issues, rather than paying for someone to come out. Turns out it WAS a simple fix and I really appreciate their helpfulness and honesty. I won't hesitate to call them the next time I need electrical help!
