Hello everyone,

Hope you can help out a layman with a problem. 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.

These days I can't get split type room air conditioners here (Greece) with R22 -- all dealers have switched to importing R410 equipment.

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 headache -- I just found out about the whole R22 - R410 busines...

Tubing has been capped off, btw, so I think no problems there.
