LOl...... had to replace the drier and muffler and charge robber o a 4 ton Trane Heat Pump. Of course the drier and charge robber are on te outside of the coil but as you know the muffler is on the inside. Was standing on a stand about 3-4 feet tall with hardly any room around the hp... so also standing on the top of a ladder propped up against said stand. So I was leaning over to replace the muffler making the bottom braze joint..... and I heard/felt (not sure which) a pop on my left side where my ribs were leaning against the top of the coil and cabinet. Didnt bother me till yesterday... now I am sore as hell. Difficult to lay down to sleep.
So you were trying to be a contortionist Well I hope you heal quickly.
