Get a portable AC. Mine weighs just 40 pounds and is on wheels. Set it up in one room that will be a cool refuge (your bedroom). Have plenty of fans in the rest of the house and drink ice water. In the winter, you can put it away in a closet or the basement. https://www.amazon.com/LifeMaster-Portable-Conditioners-Conditioner-Installation/dp/B0D3SD2S3V
