Roomie has aversion to AC

I never wanted to have a roommate, to be perfectly candid, but the state of my finances made it less of an option and more of a necessity. I selected someone who was going to grad school, because it seemed like they were laser focused on their studies and would not be overly loud of obnoxious. All of that was true, my roomie pretty much always keeps to himself and does little else besides study, so the place is quiet. There are a couple other issues, though, because he makes so pretty gross food which stinks up the whole place.  This ruins the nice indoor air quality I usually have, and those odors seems to permeate throughout every room of the apartment. It would not be such a big deal if we just turned on the air conditioner and let the air circulate through the filters to clean it up a bit. Which brings me to the other major problem I have with my roomie, his aversion to using the air conditioner. He is very sensitive to cold and cooling, he says, and when the A/C runs for too long it makes him shiver. I told him to close the air vents in his room and keep the door shut, but he says he pays rent just like me and should have a say in the thermostat settings. As a bipartisan solution, we decided that neither one of us should be happy, and we would split the different and set the thermostat in between our individual heating and cooling preferences.
