The a/c unit that I just obtained is not that great

I actually think that the older a/c units were made better, however then, I would be risking the a/c unit quitting just because of how outdated it is.

The a/c unit that I just obtained is not that great. I actually was hoping that it would be a better quality a/c unit than it is. I thought for sure that it would be a nice a/c unit because of the price that I paid for it. It wasn’t like the cheapest a/c unit in the store or anything like that. I paid quite a bit more money for the a/c unit than I was hoping to spend. I am thinking about taking the a/c unit back plus getting a odd one. I am just not sure if the next one will be any odd than this a/c unit, but someone told me that a/c units simply aren’t made the same way that they used to be… My last a/c unit was so much more durable plus nice than the modern a/c unit that I got, plus I am thinking that it is possibly because the older a/c units were made better than the modern ones are. My second idea is to take back the a/c unit that I just obtained plus buy an outdated a/c unit. I actually think that the older a/c units were made better, however then, I would be risking the a/c unit quitting just because of how outdated it is. That would be bad as well because I would be right back in the shape that I was in yupterday with no a/c unit at all. I would rather have a cheaply made a/c unit than no a/c unit at all, however as you can actually tell, I have trouble making decisions. Hopefully, I will make the right option when it comes down to it.
