We've lived in our house for three summers and have never had any problems with the air conditioner. Today I noticed that there was ice on the coolant return line outside the house. I didn't think anything of it.
Later in the day (now), the system had shut off. Even though the temperature in the house was much higher than the thermostat setting, neither the air blower nor the fan in the AC unit outside was running.
I've read that the ice on the lines may mean that the system is low on coolant. Will simply having the coolant recharged fix the problem? Do I just need to wait for something to thaw?
