I've probably been on hundreds of home inspections. When the springs are weak, that never seems to come up as an issue. Basically they're just checking to see that they open and close smoothly. If they're double hung windows, check to make sure that the window is properly in the spring. Sometimes one side is off so you've only got half the spring working. The springs are trickier to replace. If you look at the top of the window, sometimes there's a sticker inside that tells you who made the window and maybe you can contact them to get a new spring. But yeah, you're probably out of luck if the spring is bad, lots of companies don't stick around for 15-20 years to get parts from later.
They definitely do not open and close smoothly - its a bunch of springs banging around and the window hanging up every 3-4 inches. Not double hung either. I think these were probably the $250 special back in 2000.
