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.

On time, very knowledgeable, and reasonably priced. Would use them again.

David M.

Just want to thank you for sending David and Simon out for wiring and ceiling fan installation. They were the best – explained, asked for our input, etc. Real professionals. And very customer focused. Again, thank you!

Terry W.

The installers did a great job and worked quickly. They were very courteous and thorough. Went above and beyond.

Luther D.

To say the work was exemplary would be an understatement! But the most impressive part was the professionalism of Efrain and Jeff. He walked me through the project before starting, and it was spectacular!
