spent some more time working on my AC system, it's just not cold, or even cool.

I had it evacuated, a new dryer and I had a second evap under the couch plumbed in.
I put in too much duracool ( about 50 psi on the low side), I was reading the gauges wrong (oops), but then recovered the excess till I showed 25psi.

It's 90 and humid. out.

The AC, both of them, are blowing warm air.
The low side tube is warm.

The high side is only showing 55 psi?
Shouldn't be more like 255psi??

I feel like getting a new compressor, expansion valve and dryer and just starting over.

Seems like either the expansion valve is stuck open or the compressor is weak.

Either one requires opening the system again, so why not just replace them both?
