When the A/C doesn't work well

I was so happy to finally move out of my parents house. I took the first apartment that I could find in my budget. I didn’t know anything about looking for apartments and I didn’t bother to check if the plumbing worked well or even if I was responsible to pay the hot water bill. The first month in the apartment went well. All of my bills were paid and I had food in the fridge. The second month in the apartment went downhill. I started to have trouble with the AC unit. I called the landlord and he told me that I was responsible for paying for the AC repairs. I looked at my lease and I could not believe that I did not pay attention to that clause. I didn’t know what to do about the AC problems and it was only the beginning of Summer. I called my mom and dad and they paid for an AC repair company to come to the apartment. Thankfully, the repair was inexpensive. I still owe my mom and dad $400 for the cost of the AC repair, but at least I don’t have to spend the entire summer being miserable. I was in a hurry to get out of my parents house and be on my own, but I should have waited until I was more financially stable to move. My parents would have been happy to let me stay as long as I wanted. They were in no rush for me to leave. I am the youngest of three and now the house is completely empty.
