Car repair warranty by law

I got my AC in the car repaired in April 2021, and now it is not working again. I have the bill from the garage, but wonder how to approach the case. Is there a warranty defined by law how long should the system (AC) work in the car after the repairment? Unfortunately, nothing like that is stated in the bill.

Three months as I recall.

Go to them and and get it checked.

Maybe a completely different part has failed this time, maybe the same ..
