Lots of options out there.
I like MO49 primarily
or
401a for medium temp applications
401b for low temp applications
I have a 3 door reach in cooler with a bad compresor. Ive never ran into this before. Whats my options as far as putting in charge

What about the expansion valve. I can use the same???
I have several jugs of R12. Some for sale too!
I use R-414B - 100 % success
it was working.... played with it.... now its broke.... whats the going hourly rate for HVAC repair
Ft myers. But im in boston now
If I was going to change the compressor I would convert to 134A. While u have the compressor out just fluah it with rx11 and pull a good vacuum.
134a is the last refrigerant i would use....

409a

I know enough to know, I don't know enough
Why is it that those who complain the most contribute the least?
MONEY CAN'T BUY HAPPINESS. POVERTY CAN'T BUY ANYTHING
Why not 134A it's apparently using a txv most of the problems I have with 134A come from cap tube systems and waxing I have the same issues with all refrigerants using poe oil and cap tubes.
134a leaks where other refrigerants do not.... i quit using it years ago ...hate the stuff

I would say 401a but to each his own. I'm not a fan of hot snot or 134a. I've had issues w/ cap tubes & TEVs on anything running w poe including rtus .. We all know what the high temps do.
They ALL leak.Originally Posted by carmon
Every last one of 'em.
I agree with that....

I use R414B and never have had a problem.
409A for 12, and 408a for 502 work fine for me. Just depends on application.

R-401A runs a little lower head/hot gas temp so I like it a little better than R-409A. Both work fine though. No need to change TXV. I use 100% alkylbenzene oil. MP39 is claimed to work just fine with mineral oil (IIRC).
