I recently had some problems with my furnace, really simple problems. Ducts unlimited pretty much came and cleaned out my furnace, somethign that could have been done through normal maintenance. I did not know who installed my furnace and since i aout stuff like this called around and got a number of qoutes, while the price for the service was rather high by comparison to some of the others that i called they had pretty good customer service and someone was available 24/7. If it were not for the high price i would have rated them higher.
