Furnace goo? [View all]
Hi! I saw this group and wondered if anyone here could help me identify some mystery goo that's been forming on top of my furnace.
I first noticed it back in December when I went to change my filter. There was a little bit of white stuff on top of the furnace - it looked a lot like paint splatters but I know it was not paint. It seemed odd but I didn't really think much of it. When I went back to change my filter this month, there was a lot more of the goo.
I would really like to know what is causing it and if it is a safety issue of any sort. I don't have a lot of money to call someone right now so I thought I would just do some research but I don't even know what to look for (googlling 'furnace goo' didn't help me). Does anyone know what this is called or what might be causing it?
