Speaking of hot, I had a discussion with the wife about the thermostat in the house. She said it didn't work and that you have to keep adjusting it up and down. WTF? It is set on 77° and it's 77° in here. Works perfect! She said it was cool upstairs. I think sh thought that the a/c would work if it needed to cool and the furnace would automaticlly come on to heat it.
