I have just finished installing a Bryant R410Asystem (Condenser and Cooling coil).
See picture of the gauge reading (low pressure is very high, high pressure is on the low side; subcooling is where it should be (according to Bryant chart)) and the the temperature differential inside is 16-17 degree Fahrenheit. The client complains it's not cooling enough and not cooling fast enough compared to his previous R22 system.
What can the problem/s be?
What should I do to fix it/them?
Thanks

Low 132 psi
High 285psi
Low side sensor temp 77F
Superheat 32F
High side sensor temp 83F
Sub cool 9F

the low side looks normal to me but high side is pretty low when we reference with 410a. btw yours is dx or vrv.
