Central AC delivers conditioned air to the entire house through ductwork. With a forced-air system, a furnace warms air, an air conditioner cools air, a heat pump either warms or cools air, and then a blower forces the heated or cooled air through the system and out into the living spaces.
.
Just so, how does a furnace and air conditioner work together?
Both heating and air conditioning work on the principle that heat always moves from a warm object to a cooler one, just as water flows from a higher to a lower level. Furnaces and heaters put heat into the air to make your home warmer; air conditioners remove heat to make your home cooler.
how does a central air unit work? A central air conditioner cools with an outdoor compressor and condenser coil connected to an indoor furnace fitted with an evaporator coil. As the air handler pushes warm air across the coil, the refrigerant absorbs so much heat from the air that it turns into vapor.
