回复：coil 两年新，condensor是6 年新。

What I am saying is the 2012 guy should not replace your coil since the coil is probaably also 6 year new (like you condensor unit as you mentioned in your post).  R410 is not compatible with the traditional condensor.   The condensor unit outside has a plate listing the refrigent (type and volume) it allows to use.
