Bigricksstg » My AC now takes a little bit to get cold when I turn it on. It never used to do that. I have checked freon level at the low pressure port and it tells me the level is at its max. What else could be causing the air to take some time to get cold?
jimmy57 » Did you run the engine at fast idle (1200-1500) when doing the check? If not then the pressures are not valid for testing.
A safe effective thing to do is to add 1/2 standard can of refrigerant and see if it cools better. This will tell you if it is low. If it is something else then the 6 ounces of refrigerant you added isn’t going to cause harm and the correct amount will be added when the system is repaired.
On edit: I see your XC90 is a 2008. 2005 and later V8 XC90’s and all made 2007 and later have variable displacement compressors.The engine speed still needs to be high idled for checks but the VC introduces another possibility: the compressor displacement control solenoid or signalling from engine control module can be problems causing low cooling on a system full of refrigerant.

Could be the wrong amount of freon in the system. More info is required to diagnose the problem.
With engine at idle, and A/C turned onto max cool (fan can be on low circulation)… Answer the following:
Ambient Temp? High Pressure Reading? Low Pressure Reading? Compressor Cycling? How long on (compressing) and how long off?
