I live in Michigan. My lease agreement includes heat (the apartment manager pays heat and hot water). My lease agreement also states that I will control my own temperture with my own thermostat. Problem: my thermostat is turned up to 90 degrees and my apartment will not get any warmer than 60 degrees. The maintenance people have totally winterized my apartment and they say there is nothing else they can do. They don't understand why it won't get warm and they refuse to do any more work here. They told me to wear flannel pajamas and use a space heater until it gets warmer outside. Can I refuse to pay rent and do I have a case when we go to court?
