My appointment time was 8-9am.The A/C tech David was at my door at 8:05. He got right to work, answered all my questions, explained what we was doing as I asked..... because I was curious. He was very courteous and knowledgeable. This company was earned a new customer! AND, I called on a Tuesday and they gave me and appointment for the upcoming Saturday at 8am. Just what I wanted!!!!
