American Homes 4 Rent Extremely hot and humid and won't fix air conditioner, takes 2-20 times for repairs in this home. Las Vegas Nationwide

We have been in the house one year, we have had multiple maintenance issues, it takes 2-10 times to get each issue fixed. The current air conditioning problem is the icing on the cake.  I can not get them to fix our air conditionignproperly. Today it is 81 degrees, 69 percent hunmidity, 77 udegrees upstairs and 76 degrees on main floor. I am middle class hard working tax paying Lady, my Daughter is 28, Granddaughters 11 and 2. We all have allergy and asthma. The 2 y/o is Autistic, has sensory processing disorder, she cannot verbalize well, she can't tell us if she doesn't feel good.  It is so hot if we would cook, do laundry or run dishwasher it would get worse. I rent for the very reason so that I do not have to do maintenance or pay for it. I live it a nice subdivision with an HOA. i pay a lot in rent plus utilities to live here and expect things to work properly. If I had to take off every time they need to come here to fix thing, I would be fired from my job. My Dtr is able to be here to meet them. She is a College Student and takes the 2 y/o to all her therapy appts. I can't believe they don't have an on-call person in the evenings or weekends. This is a huge company all over the US. I met with 7-8 of them today and they told me the temp in my house is acceptable. I told them I want out of my lease, I was told it would cost a lot, I told them I want a quoate. They did not clean the house well either before we moved in. We did a lot. They should have replaced carpet, did not, refuse too. Since Jan. I have cleaned it twice, once professionally and I did one with good machine. It took 6 months to get toilet fixed properly. The refrigerator has never been fixed peoperly. I am still waiting for the Carpenter to look at dinign room ceiling where the toilet over flowed-has been 3 weeks. They suck you in with their viewing process and retal process but do not maintain their homes.
