Refrigerant?

You might see 325lbs on the high aide and 70-80lbs on the low side
depending on the indoor temperature. ^_^

Yes. As to which refrigerant, it's in the
subject line. Not in the text body, so it's
really hard to find information.

Normally, you look at your gages, and check
the projected pressures based on superheat and
subcooling.

With clean coils both inside & outside, an inside temperature of 75° with
50% humidity, I would expect a low side of roughly 70 PSI,
and an hi-side pressure of roughly 20-30° above outside ambient temperature
(depending on efficiency of unit) which would correspond to 243-278 PSI.
Just my opinion....

You will see that low a liquid line reading on heat pumps which usually
have a larger condenser anyway and high SEER R22 units but most of the
older R22 systems around here in Alabamastan where Summertime humidity
is often 100% will have much higher liquid line pressures. ^_^
