It's probably 30 or so at night, now, but if sunny can warm up during the day, if we catch a warm gust from the gulf.
Ours turns on aux heat as needed, but it's not often needed. Between new windows/doors and extra insulation I added (including reflective layer for summer), we stay pretty warm. It helps that it is also a relatively new and large Trane 2-zone system, which I put in when running a software company here (maybe 10 years ago? no, more than that, now, I guess). Our old system was about like yours and was on aux heat all the time. We could easily hit $500/month then and stay at $150 now all year. More money to waste on books ... and tablets ....

Our is suppose to but it seldom does. We had a freon leak this summer and they added 3lbs more I am starting to think it may need more here shortly. We've lived here close to 7 years now and no one has maintenance the furnace or the unit outside. I suspect it needs replaced. Tonight it's 25F out but it seems to be working okay. 68F in here. I got the door taped and the bottom covered with a heavy towel. Our bill runs anywhere from $60 to $150 in the winter I would say $115 is the average. It's all electric.
