AC evaporator ices up in Dallas area.

Jul 03, 2011 1 Replies

De-iced three times so far today but it keeps freezing up after running a while. Filter and fins are clean. I can see the water running. The fan motor sounds good when running and cold air blows through the vents. Do I need Freon? Or something else?? Thanks in advance for your help. Dick in Ferris, TX


If you have plenty of air flow, usually the ice means low Freon (refrigerant).

Funny how low refrigerant causes the icing,but it will.
