I have central cooling unit, and it keeps freezing up on me. The coolant lines keep freezing up on me randomly. It used to be pretty infrequent but recently it is almost every day, sometimes more than once a day.I had an ac dude come look at it, he added freon and also replaced the blower motor (which needed to be done).Ive snaked the drain line, cleaned the drain pan and cleaned the coils (which werent very dirty).At wits end here, is it possible that poor insulation on the coolant lines could cause this thing to freeze up, everything is mostly covered, but the insulation on it is fairly old and im wondering if that could possibly be my issue?Thanks for any responses!! via /r/DIY http://ift.tt/2urj1C7
