I called Arrow Electric, Inc. because I had been having a problem with the wire connection from the house to my air conditioning unit for about 2 years. There was a short in it and when the moisture would build up, it wouldn't work. Once it got dried out, it would work again. Well, it took quite a bite out of my teachers salary, but I finally had them fix it. They did a good job and I would use them again if I needed to. I will recommend them to others.
