I nearly died the other afternoon I have to tell you! What I did was really foolish due to not paying attention to things.
I had my central heating on high because it was cold earlier in the afternoon and I forgot to turn it down on the thermostat before I went to bed.
I woke up in the morning feeling as though I was in the 124 degree desert and was choking and could not breathe too well. I ran out into the hallway and turned down the thermostat of the central air conditioning as quickly as I could. I cranked the thermostat so low to try to cool the beach house off and it took about 25 minutes before I was able to get the beach house temperature back to normal. This was actually the only time in the cold winter I ever had to turn on the central cooling system! Usually it is the central gas furnace, but I had it on a bit too long. This is something I will never have happen again for sure, and I am thinking that maybe I should get myself a smart thermostat. If I got myself a smart thermostat this would have never happened because I could have programmed the smart thermostat to shut off, or at least turn itself down before I went to bed and I would have not had to remember anything! This experience has made us all decide that I need to get myself a smart thermostat for my central heating and cooling system unit. It will make life so much easier for everyone.
