Landlord is on us about HVAC care

I assume I might have the world’s most annoying landlord. 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 current place to live and I can’t wait until I am able to tell our landlord I am out. I have considered splitting our lease early too, however that would cost our a ton of cash in legal fees. So for now I am stuck with our current landlord. I assume in the previous places I have lived, I didn’t have much contact with the landlord because I don’t remember having this strenuous of a time before. My Heating in addition to A/C system has stopped blowing out cold air into our house and I have been trying to get in contact with our landlord about it for over a month now. I have been living in our house, in the middle of the Summer without the air conditioning not working properly. I have tried to call, to text and to email him however nothing has worked. I assume I am going to try and find his address and just show up to his house. I am  tired of waking up every morning covered in sweat because our air conditioning is not working. I come condo from task and our house is painfully warm. I went to the store and bought a couple of box fans to atleast get the air moving, however that doesn’t help genuinely much when it is over a single hundred degrees outside.
