This is an example of ambient plus 30 for those that are new to this forum. Lastly, I understand all the variables involved.

65 psi R22 saturation temp is 37.5. Hard to believe it’s cooling the box at that saturation temp, maybe keeping it in the low 40s. Also you have no superheat. I’d expect to find high subcooling. Sounds likely overcharged. The reason the suction pressure doesn’t change when the solenoid valve closes is because the compressor doesn’t stay ...418 psig A normally operating R-410A system with the same condensation temperature of 120 degrees and a 45 degree evaporator saturation temperature will have a high side pressure of 418 psig and a low side pressure of ...

Low side should usually be ~70-75 psi at that indoor temp and high side should be 170+psi (depending on how dirty your coil is and seer rating). And while you can't tell exactly how much refrigerant you're down without exact numbers for your system (metering device, indoor wetbulb, dirty coil) you can usually tell if you're low.

Jun 14, 2013 · 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. If the air conditioning isn’t blowing cold air and the low side pressure is too high, it could be caused by issues with the condenser fan. However, there’s also the possibility that the system has been overcharged with too much refrigerant. 1. Defective Condenser Fan. When the fan becomes damaged, airflow through the condenser is diminished.35°F. To increase latent cooling capacity. Reduce the airflow over the evaporator.
