Our AC stopped working earlier this week, late at night. We called Cornerstone the next morning, spoke with an extremely helpful and knowledgeable young lady and she scheduled an appointment for us for that same morning. James W. called and let us know he was en route, he arrived, diagnosed the problem within a few minutes, and then offered us a couple of options for the repair, explaining both in detail. We selected Option 1, and since we had to get to work, we asked him if he needed access to the house, he said no, and we went on our way and by the time we got home that afternoon, the house was cool and comfortable again! James was pleasant, professional and informative and we will absolutely use Cornerstone again should the need arise!
