Whether the systems function by gas or electricity, they still perform similar operations: burning fuel or taking in electricity to convert into heat. This is done when the cool air is blown across the heat exchanger in the furnace.
Is the air coming out of a heat pump warm or cold?
The air could be warm but still feel cool. Heat pumps usually produce air that is 85-92°F. This is plenty warm to heat your home to your desired 72°F.
