We had a 30 year old heat pump with electric back up. We always set it at 50 when going to Florida for 6 weeks in Jan and Feb and never had a problem. A year and a half ago we had a high eff.

I called the installer and he said we should not set the furnace below 60-65 as it caused the electric back up to work almost constantly. Wish we had the old unit back now, I realize it was way colder than normal last year but I was not expecting a crazy bill like this. We'll try the 60-65 this winter and see what happens.
