Edit: Context behind this question is because my parents always tell me to shut the windows all the way and I kinda feel like I’m suffocating… literally… (it’s Winter here)
Like I just struggle to breathe with windows closed…
So I’m just curious, how do y’all not suffocate while trying to keep house warm and spend less on heating?


My building is on an old chiller system, so my AC is off ~5 months out of the year. My windows are open the entire time, and I usually have fans set up too to try and keep things cool.
When my AC is on, absolutely never. It is hot here like 7 months out of the year.
