Rod arrived the same day after my morning request. He listened to my concerns and asked relevant questions. He quickly reached a hypothesis and proceeded to immediately check it out. As he had speculated, our AC was low on freon. I went with him and watched him work. That was just out of curiosity, because I enjoy watching craftsmen do their trade. He explained various things to me as he worked, and I appreciated that. As we are Gold Members, his entire visit was paid for, and we had only to pay for a pound of freon. Considering the heat that we had been dealing with, that was a real bargain. I would estimate that Rod was here about 30 minutes, maybe a little more. He was working the entire time and knew exactly what he was doing. I appreciate Interstate and I appreciate Rod. It's good to work with someone who knows exactly what he is doing!
