i have an issue that has me baffled for the first time in years....
any help would be greatly appreciated.
split system 2 ton.... evaporator is and old apollo hydro unit
no problem with the hydronic heat...
anyway....replaced condensing unit ( dead comp )
held vacuum overnight.
charged unit by weight.r22
turned system on. all should be well...but not
evap has hisssing sound and unit runs 49psi low and 178 high
added a few oz r22. pressures rise and then fall to exact as before
my question is.... is it possible to only have a leak in one direction? ( positive pressure )
or do i have another issue?
again.... any help would be greatly appreciated
