I've used this service before and had good results so

I've used this service before and had good results so I'm back with an AC issue. Today I was doing some painting so I pulled off my Honeywell Wifi thermostat from its holder/socket and unscrewed the holder/socket from the wall so that I could paint behind it. After an hour or so, I reattached the socket/holder and reseated the thermostat. The Thermostat connected to my wifi, reacquired the active heat/AC setting and reignited the AC. I live in Texas. It's hot so the AC was warranted.After a while I noticed it getting hot. Long story short, the AC is blowing hot air because the compressor outside is not running. I've since turned the entire unit off and on by power switch a few times thinking I could reset it with a "reboot". Didn't work. Checked my circuit breaker in the garage. No issues. pulled the fuse and reseated it at the compressor. No help.The compressor was working just a few hours ago. Now nothing. Any clue?
