How to fix the AC in my Vauxhall Astra?

My Vauxhall Astra's air conditioning doesn't seem to be working properly. It's blowing hot air instead of cold. What could be the issue and how can I fix it?

If the refrigerant and filter are both fine, it could be a problem with the AC compressor. This would require a mechanic's attention and may be a more expensive fix.

The most common cause of this issue is a low refrigerant level in your AC system. You can try recharging the system with refrigerant or take it to a mechanic to have it professionally recharged.

Another possible cause is a clogged cabin air filter. Check the filter and replace it if necessary. A dirty filter can restrict air flow and cause issues with the AC.
