What pressures should a 410a system run at?

A typical R-410A system should operate with a suction pressure ranging from 120 to 140 psi and a discharge pressure between 350 to 400 psi, depending on the specific application and ambient conditions. These pressures can vary based on the system's design and the manufacturer's specifications. It's essential to refer to the unit's service manual for precise pressure ranges and to ensure optimal performance and efficiency. Regular monitoring and maintenance are also crucial to maintain these pressures.
