The first technician who came out was still learning and it took him a long time to diagnose the problem. I had to wait for a part to be ordered. I was without air conditioning for two days and had to leave work twice to complete the repair which was inconvenient. In the end, we didn't need the part and if Roger had come out the first time my air conditioning would have been fixed on the first trip. Everyone needs to learn, I was lucky temps were moderate but I lost work time twice this week which was very inconvenient.
