If your A/C lines leading into you cooling coil are freezing (this is the line without the insulation), then your refrigeration system is undercharged. Expansion is occuring infront of the TX value which is characteristic of an undercharged system. You need a A/C tech to check the discharge and suction pressure on you system

Yep you guys helped me with this last fall. it was a dirty air filter and low freon. At 6 in the morning before work, I didn't even think to check the filter before calling for a repair guy. (it was like 90 that day and my wife had the Walmart Deli food poisoning. cranky )
