Why do I have condensation on my windows?
I just built a house in upstate South Carolina and moved into it this past spring. It has 2×4 wall construction with OSB, housewrap, and vinyl siding on the exterior. The walls and ceiling are insulated with blown in cellulose. I have an electric heat pump and it is equipped with a humidity control system. My windows are mid-grade vinyl. Since cold weather is setting in I am having some trouble with condensation forming on my windows on cold mornings. Is my indoor humidity too high, or is this a sign that something else is wrong?
