Newbie... AC issues
 

14' bought from Carvana. Great car so far but has had an issue with the AC from day 1 and it seems to be getting worse. We live in SE Tx so it's pretty hot here in the summer. When we first got the car, would start it up and AC would stay warm for about 5-10 minutes then the cool would kick in. Seems like it had to be driven too, meaning it would'nt seem to kick in idling in the driveway. This summer it seems to take a little longer to kick in, once it does it only blows cool for 10-15 minutes. Seems to decrease in coolnes when idling at a light then increase under driving conditions. Any similar experience or terrible suggestions? I'm leaning towards compressor beginning to fail or possible belt stretching?
