Why does my Vauxhall Astra make a strange noise when I turn on the AC?

I have noticed that whenever I turn on the AC in my Vauxhall Astra, it makes a strange rattling noise. It seems to be coming from under the hood. What could be causing this and should I be concerned?

Hi Emily, the rattling noise could be due to a failing AC compressor or a loose AC belt. I recommend getting it checked by a mechanic as soon as possible to avoid any further damage.

Emily, have you checked the AC filter? It may be clogged and causing the AC to work harder and make that noise. Try replacing the filter and see if the noise goes away.

It's possible that there could be debris or leaves stuck in the AC system. I suggest taking your car to a mechanic and having them clean it out to see if that resolves the issue.
