In the winter your attic is cold and the inside of your house is warm. Not only is it warm, but it is humid. Why?
I am sure New Hamshire winters get pretty uncomfortable. This keeps you in the home more and your body releases moisture when you breathe and sweat. You put moisture in the air when you cook (boil water). When you bath or shower you increase the humidity in your home. The warm humid air moves up through your duct system and condenses on the cold wall of your ducts. Check your Furnace or Fan coil cabinet you probably have water in there also.
Although I am not from your area, I have experienced similar problems in my area.
As for fixing it. There are many options. Try running the fan on constantly. Replace the ducts with ducts with a higher r-value. Dehumidifier. Fresh air from outside.
Don't cook, bath or shower. Breath through a pipe with a small crack in the window. Just jokin
Hope this helps
