DIY: A/C Insulation

If you replace a compressor you change the drier too.

So whats the point of a dryer?? The way you describe it is that once it dries the initial moisture in the air when the AC is used for the very first time, then dryer is useless?

It has the ability to absorb a significant amount of moisture - more than should be in the system from initial manufacturing. Once the system leaks enough to reach atmospheric pressure the dryer will most likely become saturated. Replacing the dryer, when replacing the compressor is important, since you can't easily tell the condition of the dryer and it is cheap in comparison to the compressor.

So why wouldn't they come up with a machine that dry's out the system at the factory and not install a dryer since the dryer is useless after becoming saturated from the moisture in the lines during installation. Wouldn't that be more green for the economy??
