Re: Air conditioning still poor after recharge
I don’t claim to be any sort of Alfa A/C expert, but the usual reasons for poor vent temperatures are: the blend doors in the in the climate control unit not closing properly (no idea how the Alfa design turns off the heater matrix or closes it off from the evaporator).
Not enough condenser or condenser not being cooled adequately.
And of course incorrect refrigerant charge.
One other thing strikes me, although I am not completely sure if would effect the performance, but the pollen filter, I would imagine if blocked, would reduce the air flow through the heater/AC unit, making it inefficient.
