AC stopped yesterday afternoon and we called HVAC guy who we have contract with.
He came this am with mask on. I said, oh I should put on my mask.
He said, have you been tested? I said, yes before surgery several days ago.
He said, good, I can take my mask off because I was tested and go in for gallbladder surgery next week. New normal.
Back on topic, AC problem was broken wire due either to vibration or squirrel chewing on. If I had seen it I could have fixed it myself.
