R-22 runs at much lower pressures and systems using it are therefore
cheaper and more reliable, other things being equal. A given 410a system
could be reliable enough, but only at some higher relative cost.

410a systems only exist because of politics, not technical merits.

Do you think I should plan on gettting a new R22 system by 2009 since they
stop making R22 systems in 2010? (My existing system is 20 years old)

Currently, the R-22 systems are more expensive that the R-410a systems of
the same size and efficiency

First Thank you Mr. Kinch
You are the first person that I read in these forum
about Refrigerant 410,
I personally I do not find anything good about R-410.
but then all new refrigerants are not that great
with exception of R-508B all rest run with high temp. discharge
if system develop leak on low side 9 to 1 you must change oil
because you can not take moisture out of oil, so what it's good
about this new refrigerant I have no idea.
However Manufactures loves R-410 because it makes compressors
more efficient specifically Scrowl no that is not correct, "actually all
compressors other then reciprocal" again because
it is easier for them to assemble the system and compressors are
cheaper there is no other benefits from this refrigerant

I regard to piping size you can always use higher pressure
refrigerants on the older systems that was using lower
pressure refrigerant of the same capacities.
Note yes R-22 manufacture will stop making new gas
but recycled gas will be on market for long time after that.

You must be new here....

So what?
How does that make them poor refrigerants?

A leak on the low side doesn't mean moisture will get into the system.
It's still under pressure. How do you figure external moisture is going
to overcome the pressure of the refrigerant leaking out and infiltrate
the system?

Maybe take a night school course.

Where are you getting this shit from??
Did this come to you in a dream???
