What is the low and high side pressure on a carrier split system use r-22 Freon the model no. 38hdc024310 thank you.

Can't tell you to a pinpoint because you need to know the following:
Outdoor ambient- condenser air entering temperature
Outdoor condenser air leaving temperature
Return air temperature- air temperature entering the indoor coil
Supply air temperature- air temperature leaving the indoor coil
The wet bulb temperature of the return air
Head (high side) pressure
Liquid line temperature (Small line at the outdoor unit)
Back (low side) pressure
Suction line temperature (Big line at the outdoor unit)
That said, on a 90-95* day, 70ish low, 225ish high. Also will depend on condition and cleanliness of system-dirty coils in and outside.
