Well, whenever our bestie and I moved into this house, we knew that we were going to need some extra temperature control upstairs where our home offices are located. It was clear that the top layer of our new house did not have the best insulation to trap in sizzling or freezing air, and that the windows felt pretty drafty. The two of us could tell that the air vents didn’t provide enough power to control the temperature universally throughout all of the upstairs spaces, and that additional methods of air temperature control would be required to stay on top of our indoor environment. That’s when we invested in a little portable AC unit to use in our own home office, as a way to keep the air moderately freezing at night while we slept, and well, while in the long and brutally sizzling summer time months this cooling method did the trick to keep up correctly cool and fresh throughout the night, and we considered it to be a sound investment. What we didn’t realize until last night, however, was that the AC unit was absolutely still absolutely working for us throughout this Winter season, as well, but see, when we laid down into bed last night and tried to get comfortable, it was clear that our room was way colder than the rest of the house. A draft was plaguing our bed, in particular, and we weren’t sure why the air felt so uncommon here. It took a moment or 2 before we tracked down the culprit – the portable AC unit in the corner. Since the air transfer tube was still attached firmly from the cooling method to the window, it was allowing freezing air to pour straight from the freezing outdoors, through the metal tubing, and into our room… Here we were trying to use the heat, and our AC was essentially still in operation the whole time!
