Isn't there a certain time of year that a landlord can turn off the furnace, then a time to switch it back on in the fall? This is when the temp. outside is 75 degrees during the day and down to 60 at night. she lives on the 2nd floor. My husband and I reside in the same house downstairs from her. She is one person only and has mentioned in passing that her dog gets cold. By the way, this is in Massachusetts. Also, we keep and indoor/outdoor thermostat in our house and i'm home all day and night 99% of the time. What can we do?
