Exclamation AC Discharge hose help ASAP

I just had my new discharge hose shipped, but debating on bringing it to the shop to get (if needed) excess air, debris that may have gone into the broken hose...

Can i do this myself and then recharge the freon? Cause when I had the shop recharge it about a month ago, the freon ran out in about 4 days. Now its blowing hot/ warm.

If you replace the O-rings and recharge it should be good unless there's crap in the system.

I swapped a compressor a few years ago, changed out the o-rings, and charged with the gas that has oil in it just to be safe. Cold air for teh last 2 Summers!

You need to have the system evacuated (have a vacuum pulled) before you charge it. Air mixed with refrigerant condenses moisture and decreases the ability of the refrigerant to do it's job. That moisture over time will damage the system.

I would suggest replacing the the suction line O ring at the compressor as well - both the compressor O rings harden and seep with time. Your hose should come with new O rings so you shouldn't need the high side ring.
