ac blowing hot

My 1999 wrangler will not keep Freon it leaks off. It will hold vacuum without leaking off. I put 150lbs pressure on the system and it will not leak off but you pull vacuum on system and charge the air will get cold about 40F but by next day all of the Freon is gone.

Anyone guide me to a starting point to figure out what’s wrong with the AC? I have a 2006 TJ X with about 62,000 miles. Hot air blowing when on the AC setting. Thanks.

When my tj was in the shop last it had the ac recharged and it was working good. Previously before that the ac clutch was changed because it was making an awful noice. Now my Ac blows straight hot air. I just did a new ac clutch relay hoping that would help but it still only now blows hot air...
