Property owner is a jerk

I think I might have the world’s most annoying property owner. I have been living alone in our house for about a year now and I can’t wait until our lease is up. I have already been looking for a new locale to live and I can’t wait until I am able to tell our property owner I am out. I have considered chopping our lease early too, but that would cost our a ton of cash in legal fees. So for now I am stuck with our new property owner. I believe in the previous locales I have lived, I didn’t have much contact with the property owner because I don’t remember having this strenuous of a time before. My Heating, Ventilation & A/C system has stopped blowing out freezing air into our house and I have been trying to get in contact with our property owner about it for over a week now. I have been living in our house, in the middle of the summer season without the a/c working properly. I have tried to call, to text and to text him but nothing has worked. I think I am going to try and find his address and just show up to his house. I am sleepy of waking up every afternoon tepid because our a/c is working. I come condo from work and our house is painfully warm. I went to the store and purchased a couple of box fans to atleast get the air moving, but that doesn’t help honestly much when it is over one hundred degrees outside.
