What is the correct pressure for a 2.5 ton Carrier unit?

The correct refrigerant pressure for a 2.5-ton Carrier air conditioning unit depends on the specific refrigerant being used and the operating conditions. Generally, for R-410A refrigerant, the typical suction pressure ranges from 30 to 40 psi, while the discharge pressure can range from 200 to 250 psi. It’s essential to refer to the unit's service manual for precise specifications, as factors like outdoor temperature can also affect the ideal pressure readings. Always ensure you check pressures with proper gauges under normal operating conditions.
