Why does my BMW X5's air conditioning not blow cold air?

I recently noticed that my BMW X5's air conditioning is not blowing cold air. It was working fine before, but now it just seems to blow lukewarm air. What could be the cause of this issue and how can I fix it?

It is possible that your car's refrigerant levels are low, causing the air to not cool properly. You should take your car to a licensed mechanic to have the refrigerant levels checked and topped up if necessary. It is important to maintain the proper levels for optimal performance.
