Just had a new Trane variable speed air handler installed,
to work with my Trane XL1200 Heat pump. The heat pump
is about 18 years old. Of course after turning things back on the
switchover vale seems to hang up in the cooling mode.
The installers did the best to keep things from dirt getting
where it should,but things happen.
They say that there is a lubricate to help the valve. out. Anyone had
any experince with this stuff. I will probably
end up getting a new unit, but just hope I can hold on for awhile. It
has given me not a bit of trouble, so It can be retired.
Wow, you replaced the indoor unit with a top quality variable speed unit,
yet you left the 18 year old condenser????
But back to your current problem, you're saying the tech is sloppy and got
shit into the system. Shame on them, twice!
First for selling you *part* of the system.
Second for having crappy installation practices.
First of all let me say that I am not HVAC person
However I am Refrigeration Tech with more experience then most of
guys in this forum.
To start with perhaps it is mistake replacing Evaporator assembly that is
not design to be use as you have, but never the less properly match and
system should work. question here is did the valves work ok before
system was modified, was valves been removed and then reinstall
if they was removed and reinstall, have they been install properly (in/out)
as for refrigerant I would not worry about that R-22 or replacement MX-22
will be around for many years to come and let no one tell you other wise.
lubrication for valve there is no such thing since valve is constantly
by internal oil with in the system, don't forget that valves can fail go bad
at any time
like anything else our life's nothing last forever, however I would check
are install properly and if are powered up at proper time to switch over.
KJPRO what is wrong with you, man is talking about sticky valves
and you are taking about freeze up. I strongly suggest that you change
the brand because whatever you are smoking it is not helping you!!
Once again, *try* and keep up...
Re-read this complete message and you'll find were you stated...
"I am not HVAC person" but "with more experience then most of guys in this
However, you couldn't understand *how* a simple evaporator could freeze up
in another thread... (this happened yesterday, if you can't remember).
I suggest that you *try* to understand things *before* you go posting about
things you *definately* know little about.
They're probably talking about Supco oil.
I've heard that it's supposed to help sticky RV's but I tried it years ago
& it never worked for me. The only thing that's ever worked for me & only
a couple times was unhooking the fan, driving up the head pressure &
bumping the solenoid off & on repeatedly. You'll know it if it ever shifts.
Most of the time its a losing battle.
It's curious that you're trying to save money by not changing the complete
system & yet you go ahead & put a variable speed AH in.
