My home a/c system started acting out today. Last night I noticed that it was not working so I fiddled with the switches and got it running yesterday but today I noticed that the house was warming up. I went outside and I could see the blower fan running but the compressor was not working. I could also hear a relay click on and off. Every now and then it would cycle on but more often not.

A/C guy replaced the contactor and the capacitor but it did dot help. He thought it may have been a bad thermostat but sadly, replacing it did not help.

Any other thoughts?
