A/C barely cooling and noisier under the hood

[anuck]

Hi.

Need a quick diagnosis from the forum to see what could be the issue- A/C is barely cooling and it's much noisier under the hood.

I'm wondering whether it's just the refrigerant or more serious issue.

Thanks!

If it is noisier than usual and hardly working it seems likely that something has gone wrong. Visit the dealer.
