He was early which was good but not in the time frame mentioned. Lucky i was here. He was very knowledgeable and took the time to explain things. He didn't really find anything wrong except for us to open all the inside doors so air can circulate and with metal building we still can't get the temperature below 80 degrees. He had soome good suggestions. We had this happen before and it was resolved and we did all the things he said to do but it hasn't helped. maybe because of the very hot days it is affecting they system. Me mentioned that our ducts might need cleaned but i can't afford that. All of your technicians are really good.
