Air con not working

[Sctieco]

Hi I have a 2012 focus 1.0 ecoboost had Aircon regassed but only blowing cold out of passenger side it starts to blow cold out of driver's side then it goes warm took it back to the garage they said it's the compressor any ideas thanks

I can't see how it is the compressor if you still get cold air out of one side (assuming cold means cooler than the ambient air temperature). Is it climate control or manual dials?

Likely to be a leak somewhere. When the gas gets low these tend to be cold on the passenger side and warm on the drivers side. Did it work before the re-gas?
