How did you move it?

to the room and make sure the room is inflated to 14.7 PSI.
More seriously, tell us about this "moving the AC" bit? Moved by
whom, and did he check for leaks, superheat, subcooling, etc? Did
the AC mover clean the coils, charge by weight, or....
Tell us more.

I moved the system myself. Took the air handler/furnace/evaporator
to
the attic, moved the condenser to the side of the house, re-braized
the refer. lines, and added an extrenal liquid-line filter/dryer.
checked for leaks, and the pressure test checked out. I cleaned both
the condenser and evap. coils thoroughly. Didn't check for
subcooling
or superheating, that bit is beyond me. Haven't thought aboout that
stuff since thermodynamics in college... I did add about
10' of refer. line, which leads me to believe I need more referigant.
BUT, before I do any more work, I want to know if anyone has ever
experienced the same symptoms (only 1/3 of the A-coil is cold), and
does it make sense that this may be due to low refer. level. I won't
be able to get to my gauges or referigerant for another week, but I'd
like to close up the supply ducts in the mean time. Thanks for your
help!

The above seems to mean you did NOT recover the old refrigerant, evacuate
the system, and re-charge with new refrigerant. Yes? No? (no... you can't
get to your refrigerant yet) But you cut the lines. Hmmmmm.....
If you don't have gauges, which implies 'other' fittings/adaptors as well,
how did you pressure test it properly? Tire pump? How'd you tell what
pressure you brought it up to?
How would having insufficient charge keep you from closing up the supply
ducts while you wait?

Thats your choice. Just remember that when you have to make that call to get

Stormin Mormon
classic sign of undercharge. I bet when you get your gages on the
system, you'll find the superheat way too high. Please clean the
condensor coil while you're servicing the system.
Close some ducts if you like. I'd be tempted to leave em all open
unless some rooms you don't use.

David, you have to have all the proper tools and test instruments and
know-how to do that job right.
No vac pump to properly evacuate the refrigerant lines and the
evaporator several times before releasing the refrigerant from the
condenser, assuming you did a pump-down?

Thanks for you help. What I did was supplement the original system,
which serviced the whole house, with a brand new 3 ton unit. The new
one now services the downstairs, and I moved the original one from
the
basement to the attic to service the upstairs. I left the original
refer lines in place and braized the new system to them. That has
been working perfectly for two seasons now, so I like to think I know
what I'm doing (kinda). Last weekend I finally got around to
installing the upstairs unit. Before I uninstalled it last year I
closed off the liquid valve and pumped all the referigant into the
condenser (Yes, I dust-capped all open tubing).
Last weekend I hooked up the gauges, pumped the lines and
evap coil down to 30 mm Hg with a vacuum pump while the the condensor
valves were closed, brazed up the lines at the condensor, and opened
the valves. Like I said, the new refer lines are about 10' longer
than
the original ones, so I bet you're right... I'm low on refrigant.
Just wanted to get the opinion of someone who has experienced my
problem before.

People _do_ it, but you know it's not a good idea to run a hermet under
vacuum? Arcy-sparky things can happen in the motor when the atmosphere gets
rarified. More likely to happen with air/nitrogen than freon, but still...

There was bound to be some refrigerant left on the low side, if you used the
compressor for the 'recovery' pump. That would have been what you lost when
you broke the lines; might be the source of the low charge. It ran for a
while... ok... but it might have been low from the git-go, and with some
slow leaks at the service valves/whatever, you lost enough more to send it
under the table.

Glad you added the "(kinda)" behind "I know what I'm doing" as not many
people "that know what they're doing" will reuse the old line set.

It is a compressor fault, weak pumping (compression) check the
compressor pumping through discharge port of compressor, a good
compressor discharge pressure is between 350 to 450 psi and also when
you stop the compressor the discharge pressure should not drop below
350psi secondly it could also be due to clogged condensor, clean
condensor by using condensor cleaning liquid and water pressure.

Even after the gas on the high side cools and equalizes with the low side?
Really?
My compressors are a bit, um, "hard starting" under that much head. Maybe
you have really good "hard start" kits.

With our customers, it's usually the evaporator that gets its fins linted
up... but I guess it could be fifteen years of dead lizards in there, so
yeah... just put it on full-strength from the jug, and let it soak for at
least an hour; put on plenty -- maybe even two or three applications. Then
use a hard stream of water... pressure washer is even better. Gets it
_really_ clean!

As I explained on the private e-mail you cluttered my in-box with;
OK, so if it was done right, what was your SST and your superheat?? If you
don't know what it is, then it wasn't done correctly.
If it was so easy, everybody would be doing it, don't you think??
You can screw with your R-22 system all you want, and waste all the R-22 you
want, but in just 2 1/2 years, the price is going to be a whole lot higher
to gas that system up.
