Our AC stopped working on one of the hottest days of the summer (of course). The blower in the furnace had stopped blowing. Max was quick to respond late on Saturday night. He was here by noon the next day. In the meantime I had turned the furnace off. The next day I turned it on before Max's arrival and it was working again. Seems like the problem resolved when I re-booted. Max confirmed that all seemed OK and didn't charge us a penny for the visit. Good to know Max is there for us!
