Default A/C not blowing cold air

I have a 04 wrx not blowing cold air. After doing some diagnostics I noticed the compressor was spinning, fuses were all good, and the engine was low on freon. After refilling it, it was cold but after a day it was giving constant warm air. So I have a leak some where in my ac lines, I see no fluids anywhere near my engine I keep it pretty clean, so if any fluid was to leak I would notice. Though I donít see where my ac could leak any ideas??

there are also sniffers that work for locating as well...is your pressure actually dropping or is it just getting warm? are your fans both working? have you cleared out your radiator/condenser fins?

You probably have a leak, since it blew cold after topping up on refrigerant, then went warm after leaking out. Best thing to do is get a vacuum/pressure test from an A/C professional. That will confirm your leak. Then, you'll need to have the professional use his machine to evacuate the refrigerant, which is a gas, not liquid. Once you've done that, you can add some UV Dye to the system, fill it up again, and locate the leak, which may require a black light to see the Dye. A/C diagnostic professional is the best answer. They may help you fix it yourself or not.
