need some home AC help. guy came out ....could not find anything wrong. pressure levels OK. everything OK. during the really hot days AC just quits. being fed up I installed new capacitor. first boot up, ran for about 10 minutes, then fan stopped. Also the fan is only 1-2 years old. as of now AC is running. I believe compressor is from 2010-2011. thermostat clicks so i think it's ok. so WTF is going on ? fan is newer, freon level good, capacitor is brand new. Filters are somewhat new. PS it's 116 today.
