I can remember back in the day when I had a window air conditioning unit in my bedroom growing up.
This was before central heating and air conditioning systems were a thing in residential homes.
I liked the way the window air conditioning system cooled the room, however it was so noisy that I had trouble sleeping sometimes. And in those days, there was nothing you could do about that. It was either deal with the noise of the window air conditioning system or suffer with no air conditioning system. It was rather hot in the summers where I grew up, so air conditioning was a must. There was simply no way around it unless you wanted to be in total discomfort. So what I used to do to try to combat the noise was wear ear plugs to sleep. But I could only do that on weekends when I did not have to wake up to an alarm clock for school. So you see, it was quite a hassle. I am so glad that today we all have central heating and air conditioning systems available to us that are affordable to the average joe. Because I do not think I could deal with the noisy window air conditioning systems at this point in my life getting to be middle aged heading towards old man territory. I need sleep now more than when I was a kid, so window air conditioning systems and their noisy ways would simply just not work for me today!
