I live in a house in Charlotte NC with an upstairs room. Last July during an extremely high heat index/100 degree period I notice a strange smell upstairs. It was a sweet pungent odor and it became stronger has the heat index rose. It almost has a funeral home type formaldehyde smell. Here's link to someone that has the same smell upstairs. Any ideas. The house is about 7 years old. Thanks.
