I have been living in my apartment building for almost a year now. I moved in last March, so I only experienced the tail end of winter. My apartment building consists of 5 units in an old general store building in PA. It has central heating and no A/C. There is only one thermostat in the whole building and the person that controls it, is never home. Now in the fall months the heat was on so high that I was forced to open all the windows and turn on 3 fans in my apartment. But now that the temperature is getting into the 20's and sometimes single digits, the heat is not on during the day and not very warm at night. My question is, is there a law in PA that states a min/max temperature that central heating should be set at during certain months or at certain outside temperatures?
