When checking ac what is the preasure high and low?

When checking an air conditioning system, the high pressure (discharge pressure) typically ranges from 200 to 300 psi, depending on the system and ambient temperature. The low pressure (suction pressure) usually falls between 25 to 45 psi under normal operating conditions. These values can vary based on the refrigerant used and the specific system design, so it's essential to reference the manufacturer's specifications for accurate readings. Proper pressure readings ensure the system is functioning efficiently and can help diagnose potential issues.
