Looking for normal operating pressure/temps for r-410. 14.5 seer, 2.5t new unit. 83deg outside, system was running @ 255# high side, 135#low side, liquid line temp was 84deg. Suction line temp was 64deg. I know these pressures are low, can unit be ran until weekend is over? I think undercharged? At the time house thermostat was at 78deg. Inside and set for 72 deg. Temp coming out of register was 62 deg.
