Window balance replacement

Hello,

It looks like you need to replace your coil balance. To recommend replacements, we'll need to see the pivot shoe and coils removed from the window. See the video below for assistance. 

Thanks! This photo is a huge help. Looks like you have a 15-087 pivot shoe and 15-086 coil housing. These are compatible with the Series 180 coil spring.

Your balance system is a little different from the one in our video. Namely, the spring actually nests inside the pivot shoe itself. That said, the process of removal is more or less the same. You have to remove the sash, bring the pivot shoe up to the top of the window, and then pop it out. If your window has no cutout then you'll have to make one. I recommend watching the video below for clarification.
