I won't even tell you that the AC/heater unit has been broken since June. And our rental company hasn't come to fix it. The only thing that has saved us is that our house is new and REALLY well insulated apparently. It has been cold, even for CA, but it hasn't been too bad in the house. I guess I didn't notice the humidity going up. But all is well now, and this morning we are holding at 45 on the button!!
