    If the A/C refrigerant was recently recharged and now the cooling capability is diminished, there is likely a leak. Was dye added when the recharge was performed? More importantly, was the system pressure tested to EPA standards to ensure it holds a vacuum? The vacuum test ensures there are no leaks otherwise ambient air is sucked into the system and the pressure test fails.
