I have a heat pump and love it! I spend $116 per month for heat and A/C to heat and cool a 1513 sq. ft. 3 bedroom home. This is my test of a good system. "What is it going to cost me monthly?" I keep my home at 68 degrees all year long, so you may have to adjust for your own comfort. No hot spots or cold spots either. I will say that switching to Florescent lighting made a one third drop in my energy consumption.
