1. What is the range of pressures expected on the liquid line after the metering device and before the evaporator on a typical R-22 home system? (ballpark figures)
2. What pressures would be expected on the suction line after the evaporator and before the compressor? (ballpark figures)
3. Is it possible for me to have a Pro HVAC tech install permanently mounted "steam" gauges at those two locations?
I don't have any desire to fill my own system or mess with the pressures at all. I simply want to be able to look at a gauge when/if I think my system isn't cooling and elliminate a refrigerant pressure isssue.
