Is there frost on the windows or just water running down ? Your home's humidity might be too high and should be lowered.

Thank you for that response, Dytecture. There is no frost, just heavy condensation on the inside of the windows. For instance, on days that stay around 40 degrees f. the windows are so heavy with condensation I cannot see out of them all day.
I wiped them all this morning and they are already pooling up again.
If you have a moment, will you give me an example of how to lower the humidity in our home?
Thank you again. We really do not understand this as our other home didn't do this.
We use gas heat here which I know does keep the humidity in the air. We do have a central unit that we do not use because it dries out the air too much.
