How does HVAC cooling work?

Cooling

• In the summer, your air conditioner or heat pump cools your home.
• The system uses refrigerant (a special fluid) that absorbs heat from the indoor air and carries it outside.
• The compressor and condenser coil (outside unit) release that heat into the outdoor air.
• The cooled refrigerant returns inside to the evaporator coil, where warm indoor air blows across it, cooling the air.
• That cool air circulates back into your rooms through the ducts.
