Answer:

Electric strip heat has virtually no maintainance, but is the most cost inefficient source of heat there is. The heatpump will save you some $ on operation but is usually supplemented with an electric strip that operates while the HP is in defrost mode anyway. Also the HP is a mechanical device which can be prone to breakdown and maintainance costs and because they run year round the life span is roughly 1/2 that of a central a/c unit. Lastly, heatpumps are only a viable choice in mild climates as they use the ambient heat outdoors to heat the home. So if the temps in your area are often <25-30 degrees or below I would not consider the HP. But if you are talking about a mild climate and you will be cooling or off much of the time do go with the HP.

Answer:

There is no "Con" of having a Heat Pump in comparison to electric heat. The cost difference between a heat pump and electric heat system is minimal, just a few hundred dollars. The energy savings in the first year heating will be more than the additional cost of the heat pump. If you have an air conditioner already you will not have any additional maintenance or wear and tear with a heat pump. Electric heat tends to overheat the air and causes it to be more dry. A heat pump will usually feel more comfortable. A natural gas furnace will almost always be the best choice for heating. If you live in an a area where gas is not available then a heat pump will always be preferred over electric heat.
