Until recently, I have constantly lived in houses, never an apartment. From birth until university, my parents owned a more than one-story four living room apartment up north that I grew up in. When I entered university, a few friends of mine decided to pool our money together and rent out a cheap apartment near the university. The two of us did that every year for four years until the two of us all graduated and went off to separate graduate universities. I repeated the same thing in grad university with a modern group of roommates. Now that I have my PhD and finally landed a job, I was forced to transfer to a small apartment until I can save enough money to rent out a house. Besides, it doesn’t make much sense for a single girl to rent a several living room apartment if she doesn’t even have pets or a partner to share it with. I figured that there would be some definite changes, but most of this I chalked up to losing extra space, having to downsize, and just dealing with so numerous neighbors at any given time of the afternoon. I didn’t expect the change in how the heating and cooling system is set up and installed. In all of the houses I have ever lived in, all of them had the air return for the Heating and A/C system in the ceiling above linked via ducts to the air handler, which was in a peculiar location in each home. With my apartment, my air handler is in a closet and the return is literally an opening underneath the device that links to a square hole in the wall with metal grates that apartment your A/C filter. Unfortunately, that means my air return is directly next to my floor. I didn’t guess this would be an issue until summer time hit and the heat waves and afternoon thunderstorms dropped the humidity outside and brought with it all sorts of indoor air contaminants. It seems care about I’m tracking in dirt, pollen, dust, and mold every time I walk in from outside. I’m considering buying a modern air handler if I can’t transfer soon, because my breathing is starting to get affected from the setup. I understand the constraints that smaller spaces put on apartment appliances, but it just seems counterintuitive in every conceivable way to put an return right off your floor. Most people don’t even take their shoes off when they walk indoors!
