Freon can in the fridge was just a not so great attempt to do what the commercial A/C guys sometimes do. On a hot day when the A/C guys are adding freon to a system the temperatures and pressures reach an equilibrium where the gas doesn't transfer as fast or not at all. Lowering the temperature of their freon cannister by putting it in a bucket of cool water, wrap it with a wet towel, or put it on ice will change the temperature and hence the pressure enough to get it flowing better into the a/c.
With the short fill hose, I had to hold the freon can right above the exhaust manifold and it gets hot pretty quick. A little time in the fridge helped transfer a little freon but I probably should have used the freezer. Instructions on the can also mention wrapping a wet rag around it.
Of course the right way to do it is to pull all the freon out, check the system to see if it will hold a vacuum, then refill it weighing in the proper amount. The reason I bled some off was to see how it reacted in case I was over filling it.

But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
