It’s not really running the a/c but the fan, that is what I do in the Winter time instead of running the heat.
I like to sleep in a honestly cold room so what I do is open all of the windows in the master bedroom plus powder room since the air handler is in the powder room so the cold air comes in plus circulates throughout the house.
I just run the fan since it is cheaper than the A/C plus the cool night air cools myself and others down quite nicely. I don’t open the window in my bedroom at night because the bar behind myself and others is honestly loud with partying monkees until about 2am. I put up a sound proof insulating foam contraption outside my bedroom window to block even more of the noise because it still makes its way through my double pane window plus the sound of my a/c’s colorless noise. I also wear earplugs to cut out the noise plus I have a small fan on my bed, which vibrates the bed plus lulls myself and others to sleep. I live in a Spanish city plus asking people to be quiet while they are partying is a lost cause. This is a party neighborhood with a lot of free spirits plus I am 1 of them. I need to scrub my ductwork this weekend because I have been sneezing a lot plus suspect that they are filled with dust again. I need to buy a HEPA filter 1 of these afternoons as soon as I measure the new 1.
