First time poster here. I've previously lived in apartments my entire life, but finally moved into a townhome with an attic. There is some HVAC equipment in the attic, and I think I made a boo boo. I was trying to clean up my Christmas decorations and was putting my Christmas tree up in the attic. There are a few black pipes in the attic and one of the branches of my tree got snagged on one. It put a small hole in one of these lines. I'm not sure what, if anything, I need to do to fix this. I had some packaging tape up there with me so I covered the hole with that. I have attached a picture so you can see what I'm talking about. I hope that you will tell me it is no big deal and that I'm freaking out over nothing, but as I've never dealt with this stuff before I want to be doubly sure I didn't just mess something up...

Here's one with the flash off so you can see the hole better. https://dl.dropbox.com/u/3129245/IMG_0423.jpg
