It could be leaking anywhere a hose or pipe is connected to one another.
Or the compressor.
Leaking out in a month is a very slow leak and will be hard to find.
Have the freon removed from the system.
Then get a small can of UV dye, get the pressurized kind
The ones I use are good for about 4 cars. So read the directions.
Recharge the system and keep using the AC till it stops again.
Now you have to get a UV light, I tried a cheap black light from walmart but they didn't work very good, so I finally bought a UV light made just for testing.
Now, be in a dark garage or at night, shine the light on all of the hoses, fittings, tubes, compressor, and hard parts of the AC system, the dye will have a green or yellow glow to it and that is where your leak is. Dont be surprised if you have more than one leak.
