Why does my Kia Stonic make a strange noise when I turn on the AC?

I've noticed that whenever I turn on the AC in my Kia Stonic, there is a strange noise coming from the engine. It doesn't happen when the AC is off, only when it's turned on. Is this something I should be concerned about?

It is normal for your Kia Stonic to make some noise when the AC is turned on. However, if the noise is unusually loud or persistent, it could indicate a problem with the AC compressor. It is best to have a mechanic check it out to ensure everything is functioning properly.

As the weather gets colder, it's common for cars to make more noise when the AC is turned on. This is due to the high amount of moisture in the air, which can cause the AC to work harder. Try turning off the AC for a few minutes, then turn it back on and see if the noise persists.

It's possible that there is a loose belt or worn-out bearing in your AC system that is causing the noise. It's best to have a mechanic take a look at it to determine the exact cause and get it fixed before it causes any further damage.
