I am having the same problem and was about to buy a dehumidifier (that will make me even more broke) when I saw this post! Yours sounds like it is coming from the inside of your house… if you check out my original question, you can see what we think it might be. I noticed that all three windows in our home were sweating today. One window had no condensation at all – just a tiny bit, but otherwise dry. I also noticed that one window has been dripping for quite some time now but still doesn’t have any water on the glass itself.. weird??
Anyways.. should I try to get an electrician to come check out these windows? Do they need repairs or something?
Thanks so much for answering!!
