Hello
My A/C Just work for 5-10 Min then the air become hot gradually, but when i restart the A/C it work again.
The compressor and A/C Condenser are New.
I hope someone give me the solution.
Thank you.

 

Have them recheck the freon level/ pressures and hope they put back in the right amount of pag oil

 

I put 450 g and 40 ml of oil

 

Fluid seem ok depending if the new compressor had some oil in it already. I would check the pressures next on hi and lo side. If they are both low you may have a leak somewhere. Did you have this issue before you replaced those components? If not i would check the seals on the lines you removed and both shrader valves.
Also does the condensor fan come on ?

 

Thank you SILENTM
I had to replace the compressor again, Now everything is fine.
