Air condition
 

Ok, I have a 2010 maxima that I had the compressor everything replaced and charged. My problem now is sometimes I can ride for 15 minutes before the cold air starts blowing. Especially if the car has sat for hours. When you turn it off you hear like a bubbly sound, like water going down a drain. Any ideas as to what I need to point my finger at to have looked at? Thanks in advance for all helpful advice

low on refrigerant?

Expansion valve...that's my guess.
