> When it's close to 40 °C in your home, a ceiling fan is not going to make a meaningful difference. Hottest the hottest south facing room in my house got in the UK this year was 31.8C on the 13th August. The loft got upto 43C, but that's what insulation is for. That said, you're right, things are changing. I'm looking at getting AC installed this winter (no way I was paying summer prices).
