According to Energy.gov...For climates with moderate heating and cooling needs, heat pumps offer an energy-efficient alternative to furnaces and air conditioners. Like your refrigerator, heat pumps use electricity to move heat from a cool space to a warm space, making the cool space cooler and the warm space warmer. During the heating season, heat pumps move heat from the cool outdoors into your warm house and during the cooling season, heat pumps move heat from your cool house into the warm outdoors. Because they move heat rather than generate heat, heat pumps can provide equivalent space conditioning at as little as one quarter of the cost of operating conventional heating or cooling appliances.
So while it is great that heat pumps generally are less expensive than regular heating and cooling in moderate climates, when those areas see extreme temperature changes, the heat pump needs to work harder to get those buildings to the right temperature. This means simply that during times of more extreme temperature differences the unit really needs time to get to temperature. For the heating mode this means that the unit may have to run longer and some units may need to kick into some secondary heat source, like a dual fuel unit may have natural gas as a back up or other heat pumps have heat strips that may activate to heat the air. If the heat pump has heat strips they are located inside the unit.
There are also Water Source Heat Pumps (WSHP) that move heat and do it more efficiently than any other heating and cooling technology. Their simplicity is truly amazing. They are as simple to service as a residential air conditioning unit, and they last an amazingly long time. ASHRAE estimates a more than twenty year life expectancy. That's because they don't have to work as hard as other systems to move heat from one place to another. For the design of an ideal heating/cooling system that offers individual zone control, recovers and utilizes excess heat for space conditioning or alternative uses, and serves multi-tenant needs simply and efficiently.
