The A/C was blowing warm air. I added dye and found a leak at the condenser and line from compressor to condenser. Replaced both and the line came with a new pressure switch. Vacuumed and charged the system. Getting cold air now but noticed the clutch isn’t cycling on and off. Clutch disengages if I turn off the A/C. Is this normal? What should I check?

Hello,

The clutch should disengage when the AC is switched off. This is a normal operation.

If the clutch was not cycling on or off correctly the air will not get cool.
