We have central ac & forced heat. There seems to be two smallish white pipes leading to the furnace...one warmish and the other coolish. The one that is warm is dripping water. Do you know why there would be water running to or from the furnace

The water you see is most likely condensate, part of normal operation. It could also be a 'forced condensate drain line' as well, in which condensate is gathered in a pan in the interior unit and is pumped out through a pipe, but in those special cases you usually can hear the pump running occasionally. In that case, you could have a leak on the line. Generally you find these types of systems in houses which were built on a slab, and the central air put in post-construction. With central heat and air, you always have at least 2 lines running to the inside coil from the outside unit. Usually they are copper, but your case may be different (white usually indicates PVC, which is NOT a coil coolent supply line.) Condensate lines are almost always made of PVC, and usually are 1/2 inch in diameter or less. The one thing that is somewhat puzzling about your problem is if it is a standard condensate drain (no pump), it is usually the cold metal pipe which 'sweats', not the warm one.
