While my good friend and I had one central air return for the entire dwelling situated centrally near the temperature control, my uncle had to separate air returns situated in every room.
When I was growing up, my mom was really quite strict. It’s funny to feel of now, because she has become severely cool in her older age. However, back then my good friend and I were not allowed to do much of anything. Of course, my good friend and I had curfews, expectations for our grades, and weekly chores that my good friend and I had to perform without receiving anything in return. My friend and I had to labor official tasks by the age of 15, my good friend and I were responsible for ourselves and our belongings, and my good friend and I were entirely not allowed to partake in anything risky. My mom was obsessed with keeping us from drinking and smoking, which only made us do it more, but generally, I got away with both activities. But there was one time that I was caught smoking red-handed. We’re at my uncle’s dwelling and I snuck away to the spare room for a quick smoke. I did not realize, in his dwelling the Heating and A/C system was set up differently than our central heating, cooling, and ventilation was at home. While my good friend and I had one central air return for the entire dwelling situated centrally near the temperature control, my uncle had to separate air returns situated in every room. The air handling return was generally on the opposite wall from the air vents, so that there was a steady flow of air in and out of the room when his heating or cooling system ran. Having no idea that there was an air return, I lit up and enjoyed my smoke. About 10 seconds later, my mom came running into the room and caught me kneeling in the window, with one air vent jammed and the other wide open. At least my good friend and I can joke about my lack of Heating and A/C know-how and disobedience now that I’m an adult.
