How to troubleshoot a malfunctioning air conditioning system in a Ford Mondeo?

My 2015 Ford Mondeo's air conditioning system seems to be blowing out warm air instead of cold. What could be the cause and how can I fix it?

One possible cause could be a refrigerant leak. You can check the refrigerant levels and get that fixed. Also, make sure the air filter is clean as a clogged air filter can also affect the performance of the air conditioning system.

Another issue could be a faulty compressor, which is responsible for cycling the refrigerant through the system. If you hear unusual noises coming from the engine when you turn on the AC, it's likely the compressor needs to be replaced.
