[quote=Anonymous]Heat pumps start to suck at places just slightly colder than DC. We’re on the margin of suitable winter climate for heat pumps. They work much better in places like the Carolinas and are outstanding in GA and FL. If you have a ground loop or geothermal well for the heat pump, where the evaporator coil is guaranteed never to get below 50-55 degrees, heat pumps can work great in even cold climates (we’re not “cold” here in DC) But the typical DC area heat pump set up with an outdoor unit with an atmospheric coil is right on the edge of not working here.
