Without doing an energy audit on your home I can’t say for sure. But my educated assumption would be in Baltimore you probably had either a fuel oil or natural gas furnace. It is very probable in Florida you have an electric heat pump. Heat pumps work by taking the warmth out of the outside air and through drawing the warmth out of it through the refrigeration cycle in your heat pump deliver it into your home. You are correct in noticing the difference. Most heat pumps will deliver air at the vent that is approximately 98*. A fuel oil or gas furnace will deliver air that is up to 130*. Heat pumps are economical but for the brief heating season in Florida many prefer the comfort of natural gas heat.
