I have an electric furnace with a heat pump. Problem is most of the time the air is cool. And the air conditioning unit runs all the time.I have replaced the blower motor twice and my electric bill is around 500/mth. Something does not add up on this and we need to cut everywhere to save our home. Please help

A heat pump will run a lot when it gets colder. Is it keeping the temp that you have the thermostat set on? If not you have a problem. You may have a problem with the heat pump or aux heat.
