I remember when I was a kid, our childhood home had a window air conditioning unit. Our little minds just couldn’t understand how it was still hanging in the window! This was the only air conditioner we all had in the whole house. Of course, it was in the kitchen. So you could imagine the heat the rest of the home must have felt in the dead of summer time months. We 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. I couldn’t figure what someone would think if they walked into our home in the middle of the night. The noise must’ve been so noisy. One day we all realized that it wasn’t cooling down in the kitchen as it normally should be. The bunch of us noticed that the air conditioner was not blowing out chilly air, but cool air. The bunch of us went to the phone book to find an air conditioner service specialist that could come out as well as repair it. When they came to look at the air conditioner they pulled out the filter, that we didn’t know existed, and it was dirty. Upon further inspection, the repair guy noticed the air conditioner needed a nice tune-up plus more refrigerant. This was why it wasn’t blowing chilly air. It took a couple of hours or more for the air conditioner repairman to finish. But when he did, it felt love a cool heaven in the house. I remember having one of the best night’s sleep that night growing up.
