Did you know that heating your home dries out the air? The resulting dry air absorbs moisture from you and everything inside your home. The results of dry air include the obvious such as dry itchy skin and static shocks. But did you know that viruses thrive in low humidity conditions and can actually increase the likelihood of getting colds or the flu. In addition, when heated air isn't properly humidified, it causes walls and ceilings to crack and wood floors and trim to separate.
