Air Conditioning - R22 vs R410 piping for room air conditioning (split)

Hello,

I just purchased a new home (just been constructed) that has **unused** installation (piping) for room air conditioning (split type). The installation was done two+ years ago (the house took a while to build apparently) so the piping (copper) was supposed to be used with R22.

How can I determine if the piping is ok to use with the higher pressures associated with R410? I assume that the material itself (copper) is not a problem, right?

Thanks, this is a major headache -- I just found out about the whole R22 - R410 busines...

BTW, this is in Europe (Greece, to be more specific). Also BTW, the installation was done by the tech of a Mitsubishi Electric dealership.

If the line has never been used, you can use either R-22 or R-410.

Hope they have been capped off to keep dust and moister out?

Thanks!....

I agre with Jay. If the lines have been open to the enviroment all this time make sure when they hook the new unit up that they do a good vacuum to get rid of the moisture in the lines.
