Windows hard to open/close

A home owner from Austin, TX says:
Windows are Alcoa tilt type and are very hard to open/close. When you get it down all the way (fighting it to go down) it springs back up 3-4". You have to hold it down to be able to close the latch.

Can these be adjusted or do the spiral balance have to be replaced?

Paul from SWISCO responded:
The tension might be too tight on the spirals. I would start by using a charging tool like our 75-006 to hook on to the spiral and unwind it a couple of turns. If that doesn't work, maybe add some white grease on the spiral and re-charge it with two or three turns. If both fail, then you will need a new balance.
