Heat pumps don't blast out the toasty hot air like gas furnaces and electric heat strips. The fan runs longer too. For many people, the house never seems quite warm enough. I don't know what to tell you, I'm saving loads of cash running my heat pump.
At the house I'm in now, the HVAC guy had rigged up the defrost control wrong. The first winter electric bill told me something was awry. I quickly figured out the outdoor thermistor was plugged in backwards. The outdoor unit thought it was minus a hundred degrees always, so the unit was running a full defrost cycle every time it could. I have been saving money heating the house ever since.
It's nothing fancy. Good man contractor grade system that was installed when the house was built.
