Condensate drain hose too long? Furnace short cycling and condensate backing up in tube.?

My Tempstar DC90 is having issues. The draft inducer runs (but sometimes up to 10-15 minutes), the pilot burner lights, the main burner fires and the furnace will heat, but stops short of the thermostat setpoint. If the draft inducer runs too long, chances are there is too much condensate in the tube. Condensate seems to back up in the tube quickly. Once the water is removed, the furnace fires with no problem, but continues to shut off before the thermostat setpoint is reached. The drain hose is very long-roughly ten to twelve feet from the end of the draft inducer to the end of the plastic hose. Will shortening this hose 1. enable the proper negative pressure to be created more quickly and/or 2. enable the furnace to run long enough to produce enough heat to reach the setpoint on the thermostat? Thanks in advance for any assistance.

First off, most of the time the length of the drain is not the problem. However, proper drainage can be the problem. Make sure the drain has no apparent blockage or that it is kinked in any way. Should it not be draining, it can cause some problems. Your problem sounds more like a thermostat problem. If you have an old mercury bulb type thermostat, and you heat with gas or fuel oil, then the heat anticipator on the thermostat could be set wrong. On the old tstats like that there is a very small ring with an arrow that points to different numbers around the ring. Yours should probably be set to .4 or close to that. If you have a digital tstat then consult the users guide or installers guide that came with your thermostat to set the proper setpoint range. But I would recommend an AC contractor come out and check this problem. Hope this helps.
