a/c problem

Over the summer I realized that my a/c was blowing hot air, so i went and i had r-134a put in it. it lasted about 2 months and now it is blowing hot air again. if you know what can be wrong please help.

thx

You have a leak in your AC system!! You need to go to a good shop and have them find your leak and repair it!!
