"Finally .. it is getting hotter out there no matter what some politicians say"
I remember moving from fog and overcast in 1955, because my mother suffered chronic sinus infections. We moved to Concord, California. There, as an eight-year-old until age 26 I experienced five or six SEVERE UNLABELLED El Ninos, and never EVER EVER did we have a summer where June, July, August and September did not reach 100F at least 20-30 times in that four month period. We had neighbors that included 5th generation Italian families whose memories went back to the 1880s. Listening to conversations (I had a genuine double box NWS weather station) the oldsters would laugh and say "Yes it is 108F! It is normal. Open your windows for the night and close them in the morning".
Insulation is the key. Shading from the sun is key. Proper air circulation and dehumidification is key. Adding more A/C without thinking is counter-productive.
