I had the service man come out to service the furnace. It had been neglected on my part for quite a while. He hardly got that far in and said, "you know the best thing to do at this point would be to have it completely cleaned." So I did that and he came back and finished the job after. I appreciated the fact that they didn't ding me twice, they incorporated the service call in with the bill and only charged me for one visit.
