Why do my windows fog up in the winter?
High humidity may likely be the culprit.
High humidity may likely be the culprit! Make sure you use ventilation fans in kitchens and baths to control moisture. A Home Performance with ENERGY STAR partnering consultant can check to make sure ventilation fans are venting directly outside and are venting to the capacity for which they were designed. In some cases the vent fan may have been installed to vent into the attic or may have become disconnected or blocked. The consultant can also tell you how often to operate ventilation based on your living conditions for maximum performance. If you have a humidifier, check it regularly for proper operation. It could be adding too much moisture to your indoor air. Other sources of moisture in your home such as plants, aquariums, open sump pits, and pets can add significant levels of moisture to your home.
