I have reli-built windows from a local home center.They are only 2 years old and were installed correctly.Its 29 degrees this morning here in west virginia,and my windows have moisture all over them.Its similar to a car window after the defrosters have been on.Ive checked the seels and they seem fine,and we are not running the furnace.The temp was mid 60's yesterday,dropped overnight,and will be in the 60's again today.Is this anything to worry about?BY the way,the moisture is on the inside.
