A/c Freezing up....Good morning everyone, I have a 27 scr, Ac keeps freezing up, it's been topped off and a new h2o pump installed. Plenty of ventilation. $600 plus in the hole already. Mechanic told me to get a new unit or have this on rebuilt. Unit looks like new still, I think it was replaced just before I bought the boat a year and a half ago. Any ideas??? Thank you
