I'm going to upgrade my AC, probably to a 13 or 14 SEER. Is is best to
just stick with the R22 in this case? When will R22 become more
expensive than R410? From what I understand the units are similar in
price, so that shouldn't be an issue.
If I do stick with R22, is there any need to replace the lineset? It's
15 years old? The compressor hasn't failed though, so no contamination
in that regard.
The Installers I've worked with on my last two projects were pretty much in
the Majority of going with the new R410a. There were a few Old Timers that
tried to convince me that R410a is crap and they don't install it, though I
think it was that they were not a certified R410a installer and didn't want
to get up to speed. The Bigger companies and the newer companies only
installed R410a. If you really wanted the R22 they would.
If you have to tear into walls and its going to cost you a bit to get it in
the wall, etc, then you might want to stick with R22, if you have easy
access to the lineset its not going to be that much to run a new one for the
Yes, but I think most companies are still offering both types of
compressors. I haven't gotten a comparitive estimate yet for a 410
system. The guy yesterday just wrote up an estimate for an R22 system
using the existing linesets. I didn't even know it was R22 until I
took a closer look at the model number and the brochure. I just
assumed all new systems were R410. Maybe he's trying to push an R22
system on me so as to get rid of them while he still can. For the next
estimate, I will be sure to ask about an R410 system. I'm hoping it
won't be much more expensive.

No. R22 is superior to R410 in every physical respect. The only issue is
availability of R22, which is to be artificially restricted by men with
guns (i.e., the gummint), not by the market. But this is not supposed to
happen for longer than your system today will last.
Go to epatest.com and get an EPA license and stock up on R-22 while it is
still legal. The people who did this with R-12 in 1992 made a fortune,
buying at $1/lb and reselling 5 or 10 years later for $50/lb.
what you seem to be overlooking is the bazillions of existing
commercial and residentail systems that DO contain R-22.
Do you think that all this gas will be vented? Burned or destroyed?
Not recovered & reclaimed?
And what about the countries that havent signed on board the Montreal
Protocol? I'll bet they have gazillions more systems running r-22,
until hell freezes over.
Wise? Your call.
I will NOT have R410a in my house until I have NO OTHER choice. Personal
R22 will be around for 14 more years. Before it's all gone, I think (feel,
hope, pray) there will be a better choice than R410a.
And if anyone's wondering, that's the last I will say on this, so don't ask
questions about why I won't have R410a in my house.
I emailed my potential contractor (sales guy) with questions about
switching over and replacing the lineset. The installation manager
called me back within a short period of time and gave me some helpful
info on this:
1. In a switchover, they will replace the lineset if its easy. He said
the manf recomend changing the line, but that's nothing new, they've
ALWAYS recomended changing the line even in the old days.
2. If its not easy (i.e., a ceiling needs to be torn up), they will
only recommend a replace if they feel its necessary, i.e., if they see
that oil has been trapped in there or is dripping out of the horizontal
section. He said the oil usually doesn't settle in the horizontal
3. They will do a nitrogen purge of course. He said he's heard of using
a cleansing solvent as well, but said he usually doesn't use it, as it
can introduce foreign substances as well into the tubing.
4. He installed a 410 in his own house because he got a good deal on
5. Also said he expects R22 to be around longer than either of us.
American Standard's 18 SEER is R22 so obviously they expect it to be
around a while.
6. The decison to switch over or not should be based more on the cost
or quality of the unit rather than the particular refrigerant involved.
Well, it was a pleasure talking to a professional who took the time to
explain things thoroughly. I look forward to receiving their quote in
