In the apartment I live in, the two of us have window machine ACs in each room, but there are numerous window machine ACs in our house, but it has been 5 years of living here, and I have only ever had to replace one, last week, our landlord had to come over and replace the window machine AC and did it while I was at work. I didn’t suppose that she was going to do it while I was at work and when I came house on our lunch break, she was in our bedroom replacing the window machine AC. I was glad to see that she was able to do the replacement so hastily and that she was not trying to maintenance the broken AC unit. My landlord has a track record of trying to maintenance things and it taking a long time to do so. I only had to go one evening without the AC. It was a pretty warm evening, however the two of us had the fan so it was fine. The current window machine AC is wonderful and blows certainly chilly air. The people I was with and I are sure that the replacement was the best plan because now the weather is getting warmer and warmer each afternoon. The people I was with and I are sure that there’s a way to maintenance the units, however they are absolutely cheap so it’s not that big of a deal to replace it.
