Lately my AC was acting up. It was running however ,there was no air coming out of the vent/s. I checked the freon lines, both outside and the inside unit and found they were frozen. Opened the blower unit and found the fins were frozen also (completely covered with ice formation). Turned off the both breakers for couple of hours to thaw the ice formation on the fins. After the ice formation was completely thawed turned the breakers on and switch the thermostan just to run the fan. Blower is running but seems not enough iar coming out of the vent/s. Maybe the blower not running 100% rpm? What cause? Please help!

Get an A/C guy out there to look at the system... the problem is not one you can fix yourself. Likely a low freon charge from age or a leak. (Could even be a worn out compressor) As I said... the problem can not be diagnosed or fixed by the average homeowner.
