Good Morning; When you said portable A/C I figured it was one of those "sit inside the room"
units, my parents have one. And from what I have found looking further, LG did not
use their Linear Compressors in those units. But Still, A/C & Refrigerator Compressors
Are more crap today than before. When replacing a compressor on a sealed unit techs
regularly add at least one charge port, you can do this it's not hard. Getting a Refrigerant
handling certificate can be done online, I got one more than 15 years ago so I could buy
R-12 on ebay, silly as it sounds, same for R-22 for our house unit. I think it was $50.
It's a quick course on proper handling of refrigerants & recovery.

As far as using R134a in place of R-32 I don't know about the different temps they
work at, of the proper pressures they work at, internals keep the compressor at
the proper pressures. Condenser, & Evaporator coils are specific sizes to accommodate
the different refrigerants, + the expansion valve is also different.

The oils that are in the compressor are different for each refrigerant too, you should check
to be sure the oil for R-32 & R-134a is the same, and then I guess you'll have to assume
that the oil already in the compressor is one that both R32 & R134a is going to
play nice with.


On to powering the compressor with straight 120v. - Most likely your compressor has
3 leads, a Common, Start, and Run, you will have to identify each and feed them
properly, + the run cap.

Then there is the possibility, remotely, that you have a variable speed compressor,
I forgot what they are called, but they change speed with demand, Kinda like the
GM V8-6-4 but for A/C you most likely don't have that.

You should get documentation on your unit and it's components including the
refrigerant if you really want to fix it.... Also worth the effort.

Also adding refrigerant, you will see on the unit somewhere it will say 12.5 oz of R-32
or whatever it is, this is really precise amount you will need to carefully weigh out
how you will add this. Modern recovery/refill units can do this easily.

Proceed as you wish.....


You are onto it though with installing a vintage window unit, I got an old Sharp
Unit off CL for less than $80. and love it. Our house has old Marvin Swing-Out windows,
NOT Window A/C Friendly at all.....
I had to remove the glass & make a wood holder frame and install this unit custom -
Well worth it.
