Recommendation on possible AC problem... (auto, best, valve, buy)

[Hosic]

So im wiping down my engine bay in my 2008 liberty that has been sitting for 2 months and i hear a slight hiss, i track it to the low side service port and then notice moist area under the port.... of course its leaking. I start the car and it blows cool, not cold, roughly 71 degree's in a 90 degree garage.

I go buy one of those DIY kits to add freon, when i attached it, the low side was at 25 so i add roughly enough to make it 35 (What the directions said). It didnt really make a difference, just made it 2 degrees hotter. Compressor is running and all fans seem fine.

With that in mind, can i be somewhat confident in assuming replacing the valve and having a shop properly fill the unit up with freon should fix this? IT was blowing cold before we parked it in the garage 2 months ago

Side note, the AC has never really blown cold when on normal setting, we always used recirc to get it to blow really cold

I had a slow leak, had to add about 6 oz about every 8 months. So one day I put the refill hose on the refill valve. After it takes about 6 oz, I remove the hose and about 12-15 oz of 134 shot out. Turned out that the slow leak was a defective refill valve. Got a repair kit, replaced the valve, refilled the system and never leaked again.

It’s ten years old, the most likely problem is bad seals, and the best solution is taking it to an auto AC shop to have them replaced, and the system recharged. The compressor is lubricated with oil in the refrigerant, when that leaks out the compressor will fail, so don’t wait too long.

Get a tool and try tightening the valve.
