    The overflow line will drip until the emergency drain pan is empty. If its is taking a while to drain then it might have an obstruction.

    only for the next few minutes ... after it turns on again, it'll begin to condense water out of the air and that water has to go somewhere ...

    You need to provide more info, many of the furnace condensate saddle sumps run on a timer to clear the sump. They are powered by the furnace 24 VAC transformer and pump the condensate to a laundry tub. If the furnace is 90% with PVC exhaust, the sump will always have power to clear the NG exhaust condensate when running in heat mode with NG. Check to make sure you have 24 VAC at the saddle pump when the air handler is running, then replace the saddle pump if you have voltage to it. They have an internal timer that cycles them when the 90% furnace runs for heat and also for the AC evap coil condensation. Power is tapped directly off the 24 VAC on power from the thermostat run wire just like a humidifier would be powered. Units mounted in attics can also require a drip pan under the unit with a float kill switch for this reason if the condensate drain gets clogged up.

    No, it should drip water constantly when it is running. Check your work something is wrong.

    that would depend on the humidity in the air AND weather the unit is working or not. a lot of humidity AND if the unit is ON it could drip continuously .....................
