Problems with the apartment’s central air conditioning

I have been living in this house for the past 5 years, and yet the cooling plan still has troubles, and the issue I have been having has been going on ever since I moved in. The landlord is regularly talking about repairing it, however it never seems to get repaired, or if it does, it won’t take long before it starts having troubles again. I guess many of our neighbors have moved out because of these reasons, because when it is Summer and the un-even temperatures are in the 90s, you entirely need air conditioning, it is not something you can go without. The most discouraging thing is when I was still searching for an house to rent I was particularally looking for an house with central air conditioning so that way I wouldn’t run into these troubles, however other apartments I have lived in would have windows air conditionings, or wall mounted a/cs and those just aren’t nearly as good, however central Heating as well as A/C machines are the best for apartments, and so I didn’t think I would face the same troubles, but somehow I am still stuck with Heating as well as A/C related troubles. The only reason why I am still here is because all of the apartments around me are even more expensive, and I just can’t afford it right now. So as much as it sucks to go without heating and cooling, it is just something I am going to have to get used to. I would care about to someday buy a home, that way the Heating as well as A/C device is our sole responsibility, instead of relying on others.
