00 Chevy Silverado ac issues

[Chase]

I have a 00 Silverado 5.3l, I changed the compressor, condenser, orfice tube, low pressure and high pressure sensors, pulled a vacuum, held the vacuum so I charged it up, was working good, then the low pressure valve stem was leaking, so I drained system and changed the valve and high pressure side, now my pressures are a little high, low side is right at 45 psi and high side is at 260, at idle ac blows cold but u give it gas clutch disengages and blows hot?

Get someone to read the pressures at high idle and when the clutch disengages.
