My central air conditioner quit cooling today. I looked at the outdoor unit and noticed ice on the line that leads from the outdoor unit into the house. I turned off the thermostat hoping it would thaw. Did I do the right thing, and what next?

You need to either turn the entire unit off until it thaws out completely or just leave the fan setting on FAN and turn the a/c part off. Somehow your unit got froze up - probably due to high humidity. That used to happen to me all the time in South Florida to my central a/c. Your unit should be fine after it completely thaws out. Just give it some time.

If it froze up once, it will do it again. Causes are lack of air flow ( bad or weak fan motor) lack of airflow (dirty filter, one installed backwards, dirty evaporator or condensing coils) or low on refrigerant due to a leak.

Hello Im a maintenance technician for an apartment complex. I just went oin an emergency call for an a/c unit not cooling. I took off covers and discovered that the condensing coil were caked with dust and the send line off the compress was completely iced over. Totally not breathable. After cleaning it I checked the room temp. with the temp coming from the furnace. I had a 17 degree difference cooler air coming from the vents. Im hoping that it will straighten itself out and it will not need a charge. Any suggestions?

How about the evaporater coil was it dirty also,needs cleaning,, why is evaporater coil so dirty? Running with a dirty filter or no filter at all is the worse cause, bad air flow is biggest reason for frozen up ac unit
