R410a pressures at 90 degrees.

I rarely look at pressures, mostly saturation temp. Anything above 35 degrees on low side, and under 120 degrees on high side, is my general rule of thumb. It is all dependent on the metering device, airflow (indoor/outdoor), outdoor ambient temp, inside wetbulb, superheat, subcool. Guessing is not a very good way to do it.
