How to fix the HVAC system in my Audi A2?

I recently purchased a used Audi A2 and the HVAC system seems to not be blowing cold air. What could be the issue and how can I fix it?

First, check if the HVAC system is filled with the right type and enough amount of coolant. Sometimes, this is the simple fix for a lack of cold air in your car. If this does not solve the issue, then there may be a problem with the condenser or compressor. It is best to consult with a mechanic for further diagnosis and repair.
