Didn't do it this year and now I'm paying the price. (not sure if I did it last year either) Did some of this today: but after a while, nothing would move. Could hear the pump running but very little movement on any of the rams.
Took out the drain and fill plugs and a nice green slushy oozed out! Now I get to drain, flush and refill in 20 degree weather! Worst part is I have to remove unit and both angle rams and take them into my garage so I can warm them up enough to get all the ice/water out.
Oh well, learn from your mistakes. From now on, I'm draining and replacing the fluid every year.
