I have a farmhouse built in the 1800's with no AC. I've seen it hit 100 degrees out here and it was bad, but not too bad if I was militant about keeping the windows and curtains shut during the day, and opening up the house at night to cool it off.
Today, it was 90 degrees. It hit 79 degrees in the house, which was uncomfortable, but livable.
Forecast next week is for 108 degrees on Monday. The record high temp in recorded history for this area is 105 degrees.
When I lived in Prescott, AZ the highest temp I saw was 102, and I had central air.
Looked at window AC units and they are over $200 for a cheap one. I have about 900 sq ft to cool on the bottom floor. Not sure if I can afford a window unit that would work well enough. And, not sure if there will be any available locally to buy tomorrow.
Really on the fence about spending the money for a few days of record heat, or if I should just suck it up and live to tell the tale of 108 degree temps in an old house with no AC.
