Thank you all

2017 Yukon XL SLT 46,000 Miles. Rear shocks replaced 6 months ago. I’ve noticed lately basically every time I start the vehicle that the compressor turns on - loud annoying noise- runs for 5-10 seconds and then shuts off. Is this normal for this vehicle? Should I be hearing the compressor? I understand that sometimes it comes on when towing, but that is not the case here. Thanks
