I remember my childhood home used to have of those pressing wall air conditioner units. I had never seen anything so big before. And my little mind just couldn’t understand how it was still hanging in the window! This was the only air conditioner my family had in the whole house. Of course, it was in the family room. So you could picture the heat the rest of the house must have felt in the dead of summer. Every single one of us would pull out the fans every night and put them in front of our doors to draw in the cooler air, in turn, cooling down our rooms nicely. I couldn’t imagine what someone would think if they walked into our house in the middle of the night time hours. The noise must’ve been so very loud. One day my whole family realized that it wasn’t cooling down in the family room as it normally should be. Then my family noticed that the air conditioner was not blowing out cold air, but cool air. Every last one of us went to the telephone book to find an air conditioner service serviceman that could come out and service it. When they came to look at the air conditioner unit in the wall they pulled out the filter, that both of us around here didn’t even believe existed, and it looked black. Upon further inspection, the specialist noticed the air conditioner needed a fantastic tune-up and more refrigerant. This was why it wasn’t blowing cold air. It took a couple of hours for the air conditioner repairman to finish. But when he did, it felt just like major heaven in the house. I remember having 1 of the best night’s sleep that night in the house.
