Non-Confrontational Student Seeks Advice Online As His New Roommate Jacks Up The Thermostat, Turning Him Into A Hot Mess

The HVAC system in your house is in charge of maintaining a pleasant temperature there. This is accomplished by drawing air from within your house, filtering, cooling, or heating it, and then blowing the air back inside.

Your living area may be 10°F or more warmer or cooler than, say, the bedrooms if there is insufficient return air. In the summer, a lack of return air can make rooms near the central air conditioner cooler and those farther away warmer.

This is just like the rooms that are farthest from the furnace may be excessively cold in the winter. The OP lives in a place where there are very hot summers, up to around 95 degrees.

The OP moved into an apartment at the university with his roommate, who was about to make his life hotter. So the AC in their rooms has no return air, so hot air can't be sucked out, and only cold air is pushed in via the vent.

This means that without the AC running low, it can get pretty hot fast, especially with the bedroom door closed. OP set the temperature at 68, and the next day, when his other roommate moved in, he set it to 76 degrees.

The OP started sweating in his room since it had probably gotten to over 80. Even when they turned the temperature back, this roommate would still move it up, and the OP didn't know how to go over this issue with him.
